Dog diseases


In the article I will talk about the main diseases in adult dogs and puppies. I will list the diseases of various origins and symptoms that accompany it. I'll tell you what to do if you suspect a dog's illness.

The animal body is as fragile as the human body. It is susceptible to viral, bacterial, parasitic and fungal infections. The health of the dog is influenced by genetic predisposition to certain disorders, ecological and psychological environment. Aging of the body, injuries, poor-quality nutrition have a significant impact on the well-being of the pet.

Types and symptoms of disease in dogs

Numerous canine diseases can be divided into several groups for the reasons causing them.

These include: carnivorous plague, parvovirus enteritis, rabies, viral hepatitis, otitis, laryngitis, pneumonia, Aujeszky's disease, herpes, infectious tracheobronchitis, parainfluenza, coronavirus enteritis, etc.

And nevertheless, there are common signs on which one can suspect a developing viral disease in a pet.

  • loss of appetite
  • apathy and lethargy,
  • temperature rise,
  • digestive disorders (vomiting, diarrhea, constipation),
  • discharge from the eyes
  • runny nose
  • sneezing
  • difficulty breathing.
Dog Canine parvovirus is a canine parvovirus gastroenteritis provoker The causative agent of rabies is a neurotropic virus that affects the brain.

Skin diseases manifest as redness, itching, hair loss, seborrhea, local swelling.

  • allergic (dermatitis),
  • Aranhoz, caused by parasitism of mites on the body of dogs (itchy scabies, ringworm, etc.),
  • genetic (eg black acanthosis),
  • yeast infections
  • adenitis of the sebaceous glands,
  • seborrhea,
  • Vitiligo (no skin pigment), etc.
Atopic dermatitis Juvenile cellulite


Infectious diseases are divided into:

  • protozoal (toxoplasmosis, piroplasmosis, sarcocystosis, etc.) occur when an animal is affected by unicellular protozoa organisms),
  • entomotic (lesions of fleas, lashing, lice, etc.),
  • bacterial (anthrax, tuberculosis, tetanus, brucellosis, leptospirosis, etc.),
  • fungal (various ringworms),
  • rickettsial (pathogens are parasites that infect the inner part of the cell).
The definitive host of the intracellular parasite - the dog is Toxoplasma Biting dogs

Cancer in dogs is as common as in humans.

Common symptoms that can cause suspected cancer in a dog include:

  • strong weakness (reluctance to play, run, move again),
  • loss of appetite
  • weight loss,
  • slight constant increase in body temperature
  • painful appearance (dull sad eyes, poor coat condition),
  • in cancer of the digestive system - bad breath, blood in the stool, digestive disorders (constipation, diarrhea),
  • in cardiac and pulmonary oncology, shortness of breath, cough, hemoptysis,
  • tumors of the mammary glands are manifested by swelling and discharge with blood,
  • in renal cancer, blood is found in the urine.
Breast cancer in dogs Carcinoma - a type of malignant tumor - cancer

Eye disease

The eye diseases in dogs include:

  • infectious lesions (viral, bacterial),
  • non-infectious (injuries of the mucous membrane, neoplasms, inflammatory processes, for example, when eyelid inversion or abnormal growth of eyelashes),
  • congenital, for example, deformation of the lens,
  • senile (blepharospasms, keratitis, prolapses, etc.)

Symptoms may vary depending on what caused the eye disease.

Common signs of the disease of the visual organs include:

  • conjunctival redness,
  • profuse tearing,
  • uncharacteristic discharge (purulent),
  • itch
  • puffiness
  • in some diseases - the occurrence of tumors of different colors on the eye,
  • non-standard eyelid position,
  • clouding of the lens.

Ear diseases

  • viral,
  • bacterial,
  • fungal,
  • parasitic,
  • allergic,
  • traumatic.

The attentive host will always notice the ear disease in the dog by its characteristic symptoms:

  • itch (dog paw scratches a sore ear),
  • screaming and howling when touching the diseased ear,
  • uncharacteristic discharge from the ear canal, possibly with an unpleasant odor (with purulent otitis),
  • redness of auricles,
  • swelling of the ears,
  • raid unnatural color.
Ear mite

Heart disease

Heart disease in dogs are:

Heart diseases include:

  • heart failure (acute, stagnant and chronic),
  • myocarditis,
  • myocardoses,
  • endocarditis:
  • myocardial infarction (coronary heart disease).

A pet's heart disease can be suspected on the following grounds:

  • heavy breathing, possibly with wheezing,
  • chronic dry cough
  • fainting
  • pallor of mucous membranes,
  • weight loss
  • fast fatiguability,
  • severe dyspnea after exercise,
  • weakness,
  • arrhythmia (sometimes you can feel yourself without an apparatus),
  • fever is possible,
  • flabbiness and dullness of the skin,
  • poor pulse,
  • increase in peritoneum is possible.
Cardiac pathologies in dogs proceed a little differently than if comparing animals with people

Liver diseases

  • primary, occur due to mechanical and toxic effects on the liver. For example, for injuries, poisoning, infectious),
  • secondary arises due to complications of primary diseases (after drug treatment, pathological conditions of the gastrointestinal tract, etc.).

Each has its own symptoms. Common signs of liver inflammation are:

  • weight loss,
  • lethargy and apathy,
  • digestive disorders (vomiting, diarrhea),
  • thirst,
  • discoloration of urine (acquires reddish hues) and feces (becomes light),
  • yellowing of the mucous membranes,
  • swelling in the peritoneum,
  • dizziness (loss of coordination),
  • dyspnea,
  • convulsions
  • pain in the abdominal region (noticeable when touched and in an uncharacteristic pose of the pet),
  • fever,
  • deterioration in the appearance of wool.
Yellow mucous in dogs with hepatitis

Respiratory tract

Respiratory diseases are divided into:

  • trachea and gulp (upper respiratory tract),
  • bronchi and lungs (lower respiratory tract),
  • pleura and diaphragm (chest cavity).

  • temperature rise,
  • lethargy,
  • loss of appetite
  • change in breathing (becomes frequent or slow),

  • wheezing
  • cough,
  • hoarse voice.
Dog asthma


Endocrine (hormonal) include:

  • hypothalamus,
  • pituitary gland,
  • pancreas,
  • adrenal glands
  • sex glands.
The endocrine system is responsible for the production of hormones, on which the normal growth and development of the dog depends

  • dermatitis and dermatosis (seborrhea, eczema, skin tightening, etc.),
  • neurological disorders (dog aggression, apathy, changes in taste preferences, instability of appetite),
  • inability to fertilize.

Autoimmune diseases

These conditions usually have a genetic predisposition.

Autoimmune blood disorders are manifested in anemia and thrombocytopenia. In this case, the dog's body temperature quickly rises, the sclera of the eyes turn yellow, the urine darkens, and blood appears in the feces.

Lupus erythematosus affects all organs of the dog. During the process, the body temperature rises, bleeding from the nose and intestines develop.

Skin erythema and pemphigus appear in serious lesions of the dog's skin, the occurrence of erosions and ulcers.

Rheumatoid arthritis is characterized by damage to the joints. It occurs with fever, severe pain and local swelling.

Bladder - an autoimmune disease in dogs

Worm infestations include: echinococcosis, opisthorchiasis, teniasis, etc.

The symptomatology of invasions is as follows:

  • sudden changes in appetite changes (either complete absence, or gluttony),
  • weight loss,
  • bloating
  • intestinal disorders (vomiting, diarrhea, constipation),
  • itching in the anus (dog rides on the bottom),
  • deterioration of the appearance of the coat (becomes dull and ruffled),
  • lethargy.

Canine Disease Treatment

If you suspect a deterioration in the health of the dog and the development of pathology, especially characterized by severe symptoms, you should contact the veterinary institution for advice.

The therapy performed in time is able to quickly restore the dog and save its life.

Diseases with variable symptoms cause premature death of the animal.

Dog diseases have similar symptoms. Only an experienced specialist can appoint a competent diagnostic examination to identify the true pathology. At home, such manipulations are impossible.

Many drugs have a large number of contraindications and side effects. Incorrectly chosen medication and dosage can aggravate the dog's condition and lead to death.

It is strictly forbidden to treat dogs with drugs from a human pharmacy. The active components of such drugs, effectively coping with human diseases, can kill an animal in a matter of minutes.

In the article I told about the main diseases in dogs. Listed diseases of various origins and symptoms that accompany it. She told what to do if you suspect a dog disease.

Diseases of dogs - reference information about popular diseases of domestic animals: description of diseases, list of symptoms, signs, diagnosis, modern and traditional methods of treatment

An abscess is an abscess located in loose subcutaneous connective tissue (superficial abscess) or in the internal organs and under the mucous membranes (deep abscess) in dogs.

A viral disease characterized by symptoms of lesions of the respiratory and gastrointestinal tract. Dogs of all ages are ill, but more often puppies.

The increase in the volume of lymphatic follicles of the third century. More often large dogs are sick: Caucasian Shepherd Dogs, Moscow Watchdogs, Mastiffs.

Deep folliculitis / furunculosis of the chin and lips of young dogs. The problem of acne on the face most often occurs in short-haired dogs, especially those with folds on the face (pugs, bulldogs, rottweelers and boxers). Most often occurs in puppy adolescence (5-8 months).

Disease of dogs, cats and other carnivores, caused by tapeworms of the family Taeniidae, which are parasitic in the small intestine of animals. It occurs much less frequently than echinococcosis.

Anaerobic infection. It is characterized by rapidly emerging and progressive tissue necrosis with the formation of gases in them and the absence of pronounced inflammatory events, severe intoxication.

The disease is caused by small, filiform helminths, about 6-13 mm long. They stick to the wall of the large intestine of the host.

A group of diseases caused by external parasites that feed on blood, down and wool of animals, as well as skin scales. The most famous parasites are fleas and scabies.

Rhythm and sequence of heartbeats

A chronic disease of the joints of a non-inflammatory nature, occurring in the form of degenerative-dystrophic changes in the articular cartilage and articulated bones, accompanied by reactive-reparative changes that lead the joint to deformity.

Short-term fever with bruises, hematomas, wounds, fractures, after operations.

Accumulation of fluid in the abdominal cavity.

A pathological condition that occurs when the cerebellum is damaged, the structure of the brain, which is mainly responsible for the coordination of movements and orientation of the animal in space. Types of ataxia: - Cerebellar (observed with damage of the worm, hemispheres and legs of the cerebellum), - Sensitive (occurs when the posterior columns are affected, much less often - peripheral nerves, posterior roots, the optic tubercle, cortex of the parietal lobe of the brain) - Vestibular (manifested with the defeat of any of the vestibular apparatus), - Frontal (observed with damage to the frontal lobes of the brain due to damage to the fronto-cerebral-cerebellar connections), - Psychogenic (expressed in bizarre changes in walking, usually not observed in organic nervous system).

Atrophy of pancreatic acinar cells, in which the glands responsible for the production of enzymes shrink and completely or partially lose their function.

Respiratory diseases occurring as acute or chronic inflammation of the bronchi with simultaneous involvement in the process of the trachea.

This is a local or generalized expansion of the bronchi due to the destruction of their walls. The disease develops when bronchiectasis is infected. It is treated in the same way as a form of chronic nonspecific pneumonia.

Chronic infectious disease. In dogs, it manifests itself mainly during the breeding season and causes abortions, the birth of dead or unviable puppies, as well as skipping.

Inflammation of the synovial or mucous bags of the joints, which is accompanied by an increased formation and accumulation of exudate in its cavity. Synovial bags are connective tissue structures lined by the endothelium and filled with synovial fluid that are between the bones, tendons, ligaments or muscles and reduce friction and pressure.

Small insects that feed on skin scales and dog fluff. They belong to species-specific parasites - live on only one species of animals. Vlasoyed spend their lives on the dog, clinging to the coat and skin. Laying eggs, the female firmly attaches them to the wool.

Disease affecting the skin of the auricle and the external auditory canal is very common in dogs, more common in lop-eared animals with a long narrow ear canal and long-haired breeds, as well as in German shepherd dogs and rottweilers. Breed predisposition is inherited on a polygenic basis.

Inflammation of the cornea of ​​the eye, which is accompanied by clouding and decreased vision, even blindness

Species-specific parasites (live on only one species of animals).

Displacement of the eyeball when it is out of orbit and is partially or completely outside the eyelids.

By dislocation of a joint (any) is meant a violation of its structure due to the mutual displacement of the bones forming the joint without violating their integrity. Dislocation is always accompanied by damage to the soft tissue structures of the joint: blood vessels, ligaments of the joint, its capsule, tendons of the adjacent muscles are torn. All this inevitably leads to serious dysfunction of the organ - and a separate joint, and the entire limb.

The protrusion of the vaginal wall from the genital slit to the outside

Inflammation of the gastric mucosa. There are acute and chronic gastritis, as well as catarrhal, corrosive, phlegmonous, hemorrhagic, hyperacidic, hypoacidic.

Diseases that are caused by parasitic worms living in various internal organs of dogs. Most species of worms in adult dogs parasitize the gastrointestinal tract, some of them can live in other organs (liver, lungs, heart).

Hematoma - the accumulation of blood in the cavity, which is formed during the separation of tissue as a result of hemorrhage. Lymphoextravazate - accumulation of lymph in the cavity, formed during the separation of tissue as a result of rupture of the lymphatic vessel.

The disease of the heart muscle, accompanied by a violation of the pumping function of the heart with the development of congestive (chronic) heart failure. Dilatation is the expansion, stretching of the chambers of the heart. In case of DCM, the expansion of the predominantly left ventricle of the heart occurs, and with the development of heart failure and other chambers. DCM is a thinning of the walls of the ventricles due to the development of dystrophic processes in muscle fibers, resulting in a violation of their contractile function and reduced systolic function. Dogs of large and giant breeds, predominantly males, are predisposed to DKMP disease in dogs.

Inflammation of the pancreas

Overgrowth on the skin and mucous membranes of benign tumors (papillomas).

Acute contagious disease, which is caused by the parainfluenza virus and is accompanied by lesions of the mucous membranes and inflammation of the organs of the respiratory tract. Antibody to the parainfluenza virus is often detected not only in patients, but also in apparently healthy animals, which indicates a wide spread of virus-carrying.

Inflammation of the parotid gland

Inflammation of the pericardium (heart shirt). There are acute and chronic, dry and exudative pericarditis.

Inflammation of the peritoneum. In dogs, serous, fibrinous, hemorrhagic, purulent, putrid, limited and diffuse, acute and chronic peritonitis are distinguished.

necrotic skin lesions due to constant pressure

Prostatitis is an inflammation of the prostate gland. This is an accessory sex gland, located in the pelvic region of the urogenital canal. The secret of the gland activates sperm motility. Cryptorchus males are not allowed before breeding, as this trait is inherited by prostate Adenoma - proliferation of the prostate gland.

Major skin diseases in dogs (with photos)

Aseptic eosinophilic pustules.

Aseptic eosinophilic pustulosis is a disease, the cause of which is a violation of the immune system. There is no age, pedigree or sexual predisposition.

On the affected skin of dogs with this skin disease, follicular and non-follicular papules and pustules are formed. Ring-shaped erosion is often noted. Papules and pustules can be located on any part of the animal's body. Systemic violations are not observed.

When making a diagnosis, it is important to exclude bacterial folliculitis, leaf-shaped pemphigus, pustular dermatosis and ectoparasitic diseases.

For a more accurate diagnosis, it is recommended to conduct a skin biopsy and cytological examination of the contents of pustules.

Glucocorticoids are used as drug therapy. Prednisone is shown at a dosage of 3 mg / kg daily for 7-10 days. Then you can reduce the dose and use the drug every other day.

Bacterial hypersensitivity.

Bacterial hypersensitivity is an itchy pustular dermatitis that results from a hypersensitive reaction to staphylococcal antigens.

As shown in the photo, with this skin disease pustules form on the dog's skin. There is a strong itch, which is expressed in the restless behavior of the dog and its desire to periodically itch. In addition, dogs often develop comorbidities: hypothyroidism, atony, dermatitis due to flea allergy. For a more accurate diagnosis, a skin biopsy is recommended.

It is necessary to treat the identified underlying disease. To do this, use antibiotics (for example, cefalexin at a dosage of 20 mg / kg 2 times a day). Duration of treatment is 10-14 days.

The course of treatment is long, possible relapses of the disease.

Bacterial folliculitis.

This infectious disease is characterized by the formation of follicular pustules at the site of an intact hair follicle.

Predisposing factors for bacterial folliculitis are allergic reactions, seborrhea, and various ectoparasites (especially mites).

The main symptom of this disease in short-haired breeds of dogs is the presence of small tufts of wool, which further leads to alopecia.

In dogs of long-haired breeds, seborrhea is observed, as a result of which hair loss increases. As a result, alopecia also occurs.

The first signs of the disease are follicular pustules and papules. Then crusts are formed. Wool becomes more raised. Alopecia occurs. Lesions are most noticeable on the skin, devoid of hair.

With confirmed symptoms, antibiotics (clindamycin, sulfonamides, cephalex) are used in dogs at a dosage of 20 mg / kg to treat this skin disease. Минимальный курс лечения антибиотиками составляет 3 недели.

Буллезный пемфигоид.

Буллезный пемфигоид представляет собой везикуло-буллезное язвенное заболевание кожи и слизистых оболочек ротовой полости.

There are two forms of the disease: spontaneously bullosa pemphigoid and pemphigoid, which appears as a result of the use of drugs, especially after using sulfanilamide drugs.

There is no age or sexual predisposition. The most susceptible to this disease are Dobermans and Collies.

The mouth of the dog is mainly affected. Vesicles and bulls appear on the skin mucosa border, especially in the axillary and inguinal areas. Ulcers form on the soft tissues of the paws. The disease is accompanied by itching, which is expressed in the restless behavior of the dog. Often for the second joins pyoderma.

There are not only skin, but also systemic manifestations of this disease. They are expressed as anorexia and hyperthermia.

When making a diagnosis, it is important to exclude systemic lupus erythematosus, pustular dermatosis and demodicosis.

For a more accurate diagnosis, it is recommended to perform a skin biopsy at the sites of primary lesions.

With a severe course of spontaneously arising bullous pemphigoid, the prognosis is favorable, but only on condition of timely diagnosis and the start of treatment. Requires long-term treatment with high doses of drugs. There are often undesirable side effects.

In this skin disease of dogs, a combination treatment with prednisone and azathioprine is recommended. For treatment, prednisolone is used at a dosage of 4-6 mg / kg orally 1 time per day, azathioprine at a dosage of 1-2 mg / kg orally 1 time per day.

It should be noted that both drugs should be given only together to achieve the effect, and then you can reduce the dose of drugs to the minimum effective, prescribing them every other day. During treatment, long-term control is important.

When attaching a secondary infection, antibiotics should be used (for example, cephalexin at a dosage of 20 mg / kg 2 times a day). Duration of treatment is 10-14 days.

If the disease is caused by drugs, then a homemade diet is indicated before treatment.


Vasculitis is characterized by a hypersensitive reaction that causes damage to the blood vessels. The causes of this disease can be infections, malignant tumors, diseases of the connective tissue, the use of drugs.

There is no age or sexual predisposition. The most susceptible to this disease are rottweilers and dachshunds.

Pay attention to the photo - with this skin disease in dogs, a hemorrhagic rash, bleeding bulls and ulcers appear:

Sometimes the resulting lesions hurt the animal, this is expressed in its depression.

There are not only skin, but also systemic manifestations of this disease. They are expressed as anorexia, hyperthermia and edema. When making a diagnosis, it is important to exclude systemic lupus erythematosus, dermatomyositis and frostbite.

For a more accurate diagnosis, it is recommended to perform a skin biopsy at the sites of lesions.

It is necessary to promptly identify the cause of the disease and eliminate it, and then start treatment.

For treatment, prednisone is used at a dosage of 2-4 mg / kg orally 1 time per day. In addition, dapsone is indicated at a dosage of 1 mg / kg orally 3 times a day. The duration of treatment is at least 3 weeks. Often, long-term maintenance therapy is required.


Hypothyroidism is one of the major endocrine skin diseases in dogs. There are three types of hypothyroidism. Primary acquired hypothyroidism is characterized by a reduced ability to produce hormones by the thyroid gland. In secondary hypothyroidism, insufficient hormone production occurs. Tertiary hypothyroidism is also characterized by receptor disorders.

This disease affects dogs aged 6 to 10 years. Most often, retrievers, labradors, dobermans and dachshunds fall ill.

The dog becomes apathetic, obesity, lameness, disorders of the visual and urogenital systems are noted. Especially pronounced skin symptoms. There is bilateral symmetrical alopecia. The dog's coat becomes dull. The skin becomes cold and edematous. Changes occur in the pigmentation of the skin and coat. There is seborrhea and excessive formation of earwax. Often there are bacterial and yeast infections. Itching is mostly mild, except when a secondary infection is involved. Wounds heal slowly. There is also a poor regrowth of hair after shearing.

In all cases, life-long treatment is required. Most often, prescribe levothyroxine at a dosage of 0.01-0.02 mg / kg orally 1-2 times a day. If the dog has heart disease, the drug should be prescribed, starting with a lower dose (0.005 mg / kg 1 time per day) and increasing 0.005 mg / kg every 2 weeks to a maintenance dose. Side effects are rare.

Depigmentation in the nose.

Depigmentation in the nasal area is a form of vitiligo, which is limited only to this part of the body. In everyday life, the disease is called "bodily nose." Labradors, poodles and Dobermans are most susceptible to the disease.

Pigment saturation in the nose changes from black or brown to chocolate or white. Such changes occur even in puppies.

There is no need to conduct a biopsy, unless there are crusts and ulcers. With such manifestations, it is recommended to use this method to rule out other diseases.

The treatment is not developed.


Ichthyosis is a common disease often referred to as “fish scales” due to the formation of scales on the skin of an animal. The most susceptible ichthyosis terriers.

Gray scales are observed all over the dog’s body, and the skin becomes coarse. Seborrhea appears with a foul odor. Large keratomas form on the crumbs of the paws.

For a more accurate diagnosis, a skin biopsy is recommended.

See how the symptoms of this skin disease manifest in dogs in these photos:

Ichthyosis is incurable because it requires aggressive long-term therapy.

For local treatment using 5% lactic acid in the form of a spray or ointment. Isotretinoin is used for systemic treatment at a dosage of 1-2 mg / kg 2 times a day. Duration of treatment is 2-3 weeks. Many dogs have to be euthanized.

Skin calcification.

Skin calcification is a disease that is manifested by calcification (the formation of calcium salts) of the skin. With limited calcification, a small area of ​​calcification is formed due to inflammatory lesions, foreign body penetration, wounds, etc.

With ubiquitous calcification, an extensive area of ​​calcification is formed due to diabetes and other diseases.

In chronic renal failure, lesions are found in the crumb of the paws.

Symptoms of this disease are the formation of numerous skin nodules on the skin of dogs.

Surgical removal is performed.

With a benign course of treatment should not be carried out.

Skin cysts.

Skin cysts are bag-like structures with epithelial boundaries.

Most often formed follicular cysts, filled with yellow-brown content.

It is recommended to conduct histological studies in the laboratory, which will indicate the origin of cysts.

Surgical removal of cysts is performed.

With a benign course of treatment should not be carried out.

Urticaria and angioedema.

This disease occurs against the background of an allergic reaction of the dog to drugs, chemicals, etc.

In addition, the causes of urticaria can be various physical effects (pressure, sunlight, heat) and genetic disorders.

When hives appear blisters on the dog's skin, itching is noted, which is expressed in the restless behavior of the animal. Bundles of hair are formed above the swelling area. Angioedema is characterized by swelling of the skin, itching. It can be fatal, especially if the area of ​​edema spreads to the area of ​​the pharynx and larynx.

For prevention, it is necessary to eliminate and avoid the factors that cause the allergic reaction.

Symptomatic treatment is shown: adrenaline (in the ratio of 1: 1000) at a dosage of 0.1-0.5 ml subcutaneously, prednisone at a dosage of 2 mg / kg orally, intravenously or intramuscularly.

In order to make a subcutaneous injection, it is necessary to deeply enough (2 cm) to insert the needle under the base of the fold towards the armpit at an angle of about 45 ". Insert the medicine. After removing the needle, massage the injection site with a cotton swab. , and several times. In this case, the needle does not need to be removed. It is enough to disconnect the syringe from it, take medicine through a new needle, and then remove it and connect the syringe to the needle that is under the skin.

The photo shows how to treat this skin disease in dogs:

In acute cases, you must give the dog antihistamines: for example, hydroxyzine at a dosage of 25-50 mg 2 times a day or chlorpheniramine at a dosage of 5 mg 2-3 times a day before relieving symptoms.

Lymphatic edema.

The primary disease is a disorder in the development of the lymphatic system.

A secondary disease occurs after an obstruction of the lymphatic system during inflammation, trauma or neoplasm. Primary disease occurs in juveniles up to 3 months. Breed predisposition is not observed.

In this disease, the skin of the dogs in the area of ​​the hind limbs thickens, pressed when pressed. In addition, the forelimbs, the belly, the tail and the auricles are often affected. A secondary infection may join.

When making a diagnosis, it is important to exclude edema due to obstruction.

For a more accurate diagnosis, a skin biopsy is recommended.

In case of mild disease, treatment is often not required. In moderate to severe cases, bandaging should be performed to reduce the tumor. Perhaps surgical intervention to restore the lymphatic vessels.

In addition, removal of the affected area is sometimes necessary.


With this disease, penetration into the skin of legless fly larvae. These insects are attracted by warm, moist skin, especially in areas stained with urine or feces, as well as wounds with effusions.

Predisposing factors are poor hygiene, exhaustion of a dog due to age or illness, incontinence of urine or feces.

Symptoms of this skin disease in dogs are lesions in the eye area, around the nose, mouth, anus or genitalia. Forming gaping holes with tissue necrosis and larvae inside them.

Before starting treatment, it is necessary to cut out the hair in places of lesions. Then the affected areas should be disinfected using liquid antibacterial agents (chlorhexidine, etc.). If necessary, surgical treatment of the affected skin of the dog can be performed.

It is important to remove all the larvae. After that, it is recommended to use insecticidal liquid products (permethrin, etc.) to treat the surface of the affected skin and the remaining part of the coat.

If necessary, you can use antibiotics (for example, cefalexin at a dosage of 20 mg / kg 2 times a day). Duration of treatment is 10-14 days.


Damages are formed in places of squeezing of the skin over the bones, especially in the area of ​​the elbow and knee joints, as a protective reaction to pressure. As a result, inflammation occurs. Corns are formed due to the dog being placed on a hard bed of wood or concrete.

Large breeds of dogs are most susceptible to this disease.

There are lesions in the form of oval plaques and alopecia.

Pay attention to the photo - with this disease, the lesions on the skin of dogs look like large keratomas:

When making a diagnosis, it is important to exclude demodicosis and dermatophytosis.

To prevent the appearance of corns, it is recommended to put soft material on the dog litter. Surgical removal of corns is impractical because poor healing is often observed and lesions can occur again.

Nasodigital hyperkeratosis.

Nasodigital hyperkeratosis can occur as an independent disease or as an integral part of other diseases (ichthyosis, leishmaniasis, leaf-like pemphigus, systemic lupus erythematosus, dermatosis, or skin lymphoma).

On the crumbs of the paws, solid cracking large keratomas are formed. Because of their pain when walking, dogs limp. For a more accurate diagnosis, a skin biopsy is recommended.

It is necessary to cut the area of ​​excessive keratoma growth. It is also recommended to do water compresses on the affected areas.

A good effect is provided by daily application to problem areas of a 50% propylene glycol solution. The course of treatment is 7-10 days.

These photos show signs of major skin diseases in dogs, as described above:

Other skin diseases in dogs (with photos)

Neuroma of docked tail.

This disease is characterized by the resumption of nerve growth after cupping. Most often ill Cocker Spaniels.

Formed compacted nodule, fused with the skin in the area of ​​cupping.

For the treatment of this skin disease in dogs, only surgical removal of the neuroma is applied.


The types and extent of burn injuries depend on the primary exposure.

The most common are chemical and sunburn.

Burns are partial lesions. After their healing, the scars do not remain. With deep burns, all structures of the skin are damaged, extensive scarring is observed.

Often, lesions on the dog's skin do not appear within 48 hours. Then the skin becomes hard and dry. Hair can hide the full spread of lesions. After a couple of weeks, the infection joins, which leads to suppuration.

With this disease, there are not only skin, but also systemic manifestations. Most often they occur with the defeat of more than 25% of the body. Septicemia, renal failure and anemia are noted.

In severe cases, it is very important to conduct a kidney examination. Treat the skin with antiseptic agents. Requires surgical treatment of wounds. Topically use antibacterial ointment. Glucocorticoids are contraindicated.


Frostbite occurs during prolonged exposure to low temperature or after contact with frozen objects. Certain lesions depend on exposure to the skin.

Mainly affected fingers, ear area and tip of tail. The skin becomes pale.

The affected area is cold, and when warming, erythema is formed, tissue death begins. In severe cases, rejection of dead areas occurs.

When making a diagnosis, it is important to exclude vasculitis.

Avoid exposure to cold. Quickly warm frozen tissue with warm water. Damage can heal spontaneously. Surgical excision of necrotic tissue may be necessary.

Focal scleroderma (ring-shaped).

Focal scleroderma is a rare skin disease that occurs due to vessel damage, abnormal collagen metabolism, or an autoimmune disease.

There is no age, sexual or pedigree predisposition.

With this disease, shiny sclerotic plaques with alopecia are formed on the dog's skin, which are located mainly in the area of ​​the body and limbs. Systemic violations are not observed.

The main manifestations of this skin disease of dogs are shown in the pictures:

For a more accurate diagnosis, a skin biopsy is recommended.

This disease is not considered dangerous. Spontaneous recovery is often observed, so special therapy is not required.


Pediculosis is a skin disorder that is caused by lice and itching. There are two types of lice: biting and sucking. Biting lice cause more skin irritation than sucking. This disease often occurs in winter.

When describing this skin disease in dogs, it is worth noting that lice are mainly localized at the tips of the ears and in matted pieces of wool. Sucking lice can cause anemia and animal depletion. Often formed papular rash, which lead to scratching. Predisposing factors are poor hygiene, unbalanced nutrition, crowded housing of animals.

To properly diagnose, you need to know the characteristic signs of lice. These are small wingless insects 2-3 mm long. They have 6 legs and a wide head. Sucking lice move slowly, so catching them is pretty easy, and biting lice are active.

With confirmed symptoms of pediculosis, before starting treatment for this skin disease in dogs, it is necessary to trim the hair in order to remove thick crusts and matted hair and to facilitate access to the affected areas. Для лечения следует ежедневно в течение 7 дней использовать специальные инсектицидные шампуни или 1%-й раствор сульфида селена. Рекомендуется провести 3 курса с 10-дневным интервалом. Также для ежедневного мытья собаки можно использовать 1%-й раствор перметрина. Кроме того, необходима дезинсекция места содержания животного и предметов ухода за ним.

Синдром Кушинга.

As a result of Cushing's syndrome in dogs, the concentration of cortisol circulating in the blood increases. There are naturally occurring syndrome and acquired as a result of prolonged excessive use of steroid drugs in the form of injections, tablets or their local application (in the eyes, ears or on the skin). This disease affects animals of middle age, of any gender and of any breed, but most often boxers, poodles and dachshunds are sick.

In dogs, apathy, low stamina during training, changes in behavior, sagging belly, shortness of breath. There is a change in coat coat color and condition. After shearing hair grows very slowly.

Alopecia is usually bilateral symmetrical on the sides, but not affecting the distal parts of the body.

As shown in the photographs, in this disease, the skin in dogs becomes thinner and loses its elasticity:

Bruises are easily formed on the dog’s body, and wounds do not heal well. Seborrhea is noted. Bacterial and yeast or tick-borne infections may occur.

Before treating Cushing's syndrome, it is necessary to cure other diseases (if any): diabetes mellitus and urinary tract infection. Surgery and radiation therapy may be required.

There are conservative methods of treatment. Cyproheptadine hydrochloride is prescribed at a dosage of 0.5 mg / kg per day orally and bromocriptine mesylate at a dosage of 0.1 mg / kg per day. The course of treatment is 7-10 days.

In addition, selegiline hydrochloride is indicated at a dosage of 2 mg / kg orally. The course of treatment is 3-4 weeks. It can then be extended to 6 weeks.

You can use ketoconazole at a dosage of 10-30 mg / kg per day orally until a positive reaction to treatment appears.

Black Eel Schnauzer Syndrome.

This rare disease occurs only in miniature schnauzers. It occurs due to the development of hair follicles.

Observed formation of black "heads" in the back. Bacterial infection may re-join. Itching is mild.

Long observation is required.

Anti-seboric shampoos should be used as a topical treatment, especially those containing sulfur, salicylic acid, tar, and benzoyl peroxide.

Isotretinoin is used in the treatment of a second-time infection at a dosage of 1 mg / kg 2 times a day. Duration of treatment is 14-20 days.

Systemic histiocytosis.

Systemic histiocytosis is a rare disease due to excessively rapid cell growth in the internal organs and skin. Most often sick dogs aged 2 to 8 years. There is no sexual or breed predisposition.

This disease causes the formation of plaques, nodules and ulcers all over the dog’s body, especially in the area of ​​the muzzle, eyelids and scrotum. Not only skin but also systemic manifestations of the disease are noted. The dog becomes exhausted, there are dysfunctions of the respiratory and musculoskeletal systems.

Before treating this skin disease in a dog, it is recommended to conduct a skin biopsy and laboratory tests of the contents of the lesions and lymph nodes.

Bad effect with chemotherapy. Successful treatment can be 5 courses of the bovine fork of the spectacle gland.

Toxic epidermal necrolysis.

Toxic epidermal necrolysis is characterized by a severe skin immunological reaction, the cause of which may be infections, systemic diseases, various neoplasms or the use of drugs.

Lesions on the skin of the dog are found in any part of the body, but more often they are found in the area of ​​the mouth, skin mucous rims and limbs. Erosions and ulcers form on the skin, vesicles and bullae appear. There are not only skin, but also systemic manifestations of this disease. They are expressed as anorexia and hyperthermia. The state of the animal becomes depressed. When making a diagnosis, it is important to exclude systemic lupus erythematosus, erythema multiforme, lymphoma and burns.

For a more accurate diagnosis, it is recommended to perform a skin biopsy at the sites of lesions.

The prognosis is often unfavorable. It is important to promptly identify the cause of the disease and eliminate it, and then begin treatment.

In some cases, treatment with glucocorticoids is recommended.

Follicular dystrophy of black / dark hair.

Follicular dystrophy of dark hair is a familial disease that occurs in two-color or tricolor puppies. When this happens, only black or dark hair is damaged. It is assumed that the defect in hair growth is associated with impaired pigment transfer.

Collies, dachshunds, pointers, and also hybrids are most susceptible to this disease.

There is a progressive loss of black hair due to the fragility of their rods. This process occurs from 4 weeks of age puppies. Manifested in the form of alopecia or looks like short-cropped hair.

When making a diagnosis, it is important to exclude demodicosis and dermatophytosis.

When a second-time infection appears, treatment with antibiotics is indicated (for example, cefalexin at a dosage of 20 mg / kg 2 times a day). Duration of treatment is 10-14 days.

The symptoms of this skin disease in dogs are shown in the photo:


This skin disease occurs in dogs when deep-infected follicles rupture inside the dermis.

Primary follicle damage can be caused by bacteria or parasites (most commonly ticks). The main causes of canine furunculosis are seborrhea, suppression of the immune system, dermatitis resulting from the action of drugs, and allergies.

Symptoms depend on the severity of the disease. First, separate papules appear, subsequently progressing to ulcerated pustules with the formation of crusts. In the most severe cases, red purple papules form in the affected areas of the skin with the formation of a fistula, from which liquid is secreted. Then there is the formation of crusts.

For the treatment of furunculosis, antibiotics are used (for example, cephalexin at a dosage of 20 mg / kg 2 times a day). Duration of treatment is 10-14 days.

It is necessary to shave out the hair on the affected areas and disinfect the skin. In addition, antibacterial compresses and baths are shown. You can use lotion with callamine. Glucocorticoids are contraindicated.

It is important to treat the main diseases that cause furunculosis.

Aseptic panniculitis.

Aseptic panniculitis may occur in the form of single lesions that are associated with injury or ingress of foreign bodies. In other cases, multiple lesions that are associated with impaired activity of the immune system, various diseases (systemic lupus erythematosus, pancreatic dysfunction, etc.) may also occur.

Pay attention to the photos - with this skin disease in dogs, single lesions appear in the form of deep-lying nodules, on the site of which ulcers with yellow oily or bloody secretions subsequently form:

Such lesions are most often noted in the neck, abdomen and on the sides.

In other cases, there are multiple lesions on the dog's skin.

By structure, they are the same as single lesions, but usually occur on the trimmed areas of the back and on the sides.

Not only skin, but also systemic manifestations of this disease are noted. The animal has no appetite, the dog becomes apathetic. With the defeat of the pancreas, vomiting is observed.

When making a diagnosis, it is important to exclude aseptic pyogranulomatous disease and neoplasms.

For a more accurate diagnosis, it is recommended to conduct a skin biopsy and cytological examination of a smear of ulcerative secretions.

Also shown are blood samples for antibodies that control the work of the pancreas.

For single lesions, surgical intervention is indicated. For multiple lesions, prednisone is used at a dosage of 2 mg / kg once a day for 2–3 weeks. Then the dosage must be reduced and use the drug for another 1 month.

Relapses often occur and longer treatment is required. To maintain prescribed vitamin E.


Haletiosis is a common disease of dogs in which parasites (large ticks) do not move under the skin, but live and parasitize on its surface. Young dogs are most susceptible to cheiliozia.

The disease is transmitted to humans: papules appear in places of contact with animals, which are accompanied by itching.

Most often there is a peeling in the back of the animal with increasing itching, which leads to scratching. Sometimes specific symptoms may not appear.

It is necessary to treat not only the diseased, but also all the animals that have come in contact with them. To do this, it is recommended to use antiparasitic shampoos or solutions for washing wool (1% solution of selenium sulfide or 1% solution of permethrin). It should be 3 courses at intervals of 10 days.

In addition, disinsection with insecticidal environmental sprays at the location of the diseased animal is shown. To do this, you must use permethrin and cyromazine.

The photo shows which medications are used to treat this skin disease in dogs:

Black acanthosis.

Black acanthosis is associated with allergies, chronic skin itching and endocrine diseases. Acantosis of this origin is considered secondary. Dogs of any breed are subject to this disease.

Primary black acanthosis is of a genetic nature. Dachshunds are subject to it.

This disease is observed in young dogs under the age of 1 year.

The main symptom of primary black acanthosis is hyperpigmentation of the axillary region of dogs. In the chronic form of this disease, seborrhea is noted. Lesions can spread with the involvement of larger areas. Often there is a secondary accession of the infection. Secondary black acanthosis has similar manifestations.

Skin biopsy for black acanthosis is not informative.

Treatment of the underlying disease should be carried out with secondary black acanthosis. Local therapy is indicated. To do this, use a cream with steroid drugs. It can only be used for a short period. Good effect give anti-seborrheic shampoos.

Also in veterinary medicine, melatonin and prednisone are used to treat this skin disease in dogs. Melatonin should be given at a dosage of 2 mg daily for a week, and then once a week or once a month as maintenance therapy. Prednisolone is shown in a dosage of 1 mg / kg once a day, daily for 7-10 days, then in the minimum effective dose when applied every other day. Vitamin E is also prescribed.


This disease is caused by ectoparasites. Dog scabies is a contagious disease and is transmitted to humans. A person has lesions in the form of papular lesions on the hands and on the body.

Sources of infection for dogs are often sick foxes.

When scabies form papules with crusts and scales. Lesions are most often noted in the area of ​​the ears, abdomen and knee joint. With the progression of the disease, papules appear throughout the entire body of the dog.

Due to itching, scratching is often formed. Often the dog tries to scratch, which indicates irritation of the edge of the auricle.

For a more accurate diagnosis, it is recommended to take scrapings of the skin of an affected dog. Before scraping wool should be shorn. Sometimes serological tests are also used.

Before the treatment of this skin disease is started, the dog's fur in the areas of lesion must be cut short. To facilitate the process of grooming the dog can be sedated with sedatives. Then you should wash the dog with antiseborrheic shampoo. In addition, you should swim the dog in water with the addition of a 5% solution of amitraz (in a ratio of 1: 200). The course of treatment is 5 days.

Treatment procedures should be applied once a week for 6 weeks. Mil-bemycin oxime is also prescribed at a dosage of 0.2 mg / kg orally 3 times every 7 days. When treatment is allowed to use glucocorticoids (prednisone at a dosage of 1 mg / kg once a day). The course of treatment is 7-10 days.

It is recommended to disinfect the room where the sick animal is kept. Permethrin / cyromazine and pyrethrin / methoprene can be used for this.

Eosinophilic granuloma.

Eosinophilic granuloma is a genetically determined disease that occurs as a result of a reaction to environmental allergens. The most susceptible to this disease is the Siberian Husky. Most often sick dogs under the age of 3 years.

Eosinophilic granuloma is characterized by the formation of plaques, nodules, which often turn into ulcers, especially in the oral cavity, on the surface of the abdomen and on the sides.

Systemic violations are not observed.

When making a diagnosis, it is important to exclude infectious and aseptic granulomas and tumors.

For a more accurate diagnosis, a skin biopsy and hematological examination are recommended.

For the treatment of this skin disease in dogs, prednisone is used at a dosage of 1-2 mg / kg once a day, every day for 2-3 weeks.

In most cases, this therapy is sufficient and further treatment is not required.

Noncrolithic erythema migrans (hepatitis skin disease).

Necrolytic erythema migrans is a rare cutaneous manifestation of an internal disease, usually the pancreas or liver. Most dogs with this disease have severe liver damage, often with pancreatic pathology. It is also believed that a lack of biotin, essential fatty acids or zinc contribute to the development of the disease.

Old dogs are mostly susceptible to this disease. Breed predisposition is absent.

Erythema occurs mainly on the knee and elbow joints, skin-mucous rim in the area of ​​the muzzle and the crumbs of the paws. Crusts, erosion and ulcers are formed.

With this disease, there are not only skin, but also systemic manifestations. Dogs become apathetic and exhausted.

When making a diagnosis, it is important to exclude systemic lupus erythematosus, zinc deficiency, leaf-like pemphigus and general dermatosis of dogs for food components.

For a more accurate diagnosis, it is recommended to perform a skin biopsy, laboratory blood tests and an ultrasound of the liver.

Treatment and Prevention

The prognosis is unfavorable. In most cases, dogs die or are put to sleep.

In some cases, surgery is possible.

With conservative treatment, there has been varying success with short-term treatment with corticosteroid drugs.

On these photos you can see the signs of skin diseases of dogs, the description of which is presented in this material:

Helminths and fleas

These are very common ailments, so let's start with them. Studying the symptoms of diseases in dogs, many overlook the possibility of worm infestation. But the presence of parasites in the body reduces immunity, contributes to the development of intoxication, and in severe cases leads to the death of the animal. Worms are dangerous not only for puppies, but also for adult animals. Here are some signs that suggest that deworming procedures should be carried out:

  • The dog's belly is round, inflated.
  • She starts to eat less, loses weight.
  • Usually reduced activity.

If you notice these symptoms, then you need to buy the most benign remedies at the pharmacy and give your pet the necessary dose. In no case do not overstate it, because the body can not cope with a loading dose. The treatment is carried out individually, under the supervision of a veterinarian. Be sure to 2-4 times a year to carry out preventive measures.

Often there are fleas in dogs. Symptoms of the disease are pretty obvious. The animal begins to bite itself by the skin, catching insects, scratching its paws and express anxiety. For the treatment of this ailment sprays and drops are used, which in a large assortment will be offered to you at any veterinary pharmacy.

What are the diseases in dogs?

Today, owners often believe that animals cannot get sick and do not feel pain. And if the pet refuses to eat, it must be given vodka to drink, and the illness will recede. Any veterinarian will say that it is not. Symptoms of diseases of dogs are very different, and the owner must at least a little understand what is the norm, and in what cases to run to the doctor. And of course, you can not water animals alcohol.

In many cases, you can immediately understand that something is wrong with the dog. She does not eat and drinks a lot, often lies. Usually, a cheerful pet stops playing, in the eyes of melancholy. Wool fades and begins to fall. The animal's stool is also changing, diarrhea often appears, and sometimes with blood. All this suggests the presence of symptoms of the disease in the dog. Treatment (the photo does not make it possible to make an accurate diagnosis, therefore, consultations on the Internet are ineffective) should be prescribed only by the attending veterinarian.

Самые распространенные заболевания можно разделить на несколько категорий:

  • Инфекционные.
  • Внутренние незаразные.
  • Хирургические.
  • Паразитарные

Давайте теперь подробней остановимся на каждой из категорий.

Паразитарные заболевания

Потенциально опасные для всего окружения питомца, поскольку их вызывают паразиты. But in practice it turns out that the infection occurs by unicellular organisms and is not transmitted from dog to dog. For a person, these diseases are not at all dangerous. But it is extremely important to know the symptoms of disease in dogs. The treatment (the photo sent to the vet will not replace a visit to him) is often only successful at the initial stage. In advanced cases, the pet is waiting for death. This category includes one of the most common diseases.


A deadly malady that strikes a huge number of animals at the beginning of spring. The pathogen is transmitted by ticks. Currently, the disease is widely distributed throughout Russia. How does this disease in dogs?

Symptoms (a photo of a sick animal shows that the condition worsens already in the first hours after infection) develop rapidly. The pathogen enters the bloodstream along with the mite's saliva and begins to destroy the red blood cells. As a result, the internal organs do not cope with such a load. The spleen, liver and kidneys suffer, oxygen starvation occurs. Symptoms are:

  • High temperature (up to 42 degrees).
  • Yellowing of the proteins of the eyes and mucous membranes.
  • Urine acquires blood.
  • Apathy, refusal to eat.

Therapy involves the intramuscular injection of a toxic substance that will cause the death of the parasites. And then the recovery course for the dog itself.

Diseases of the internal organs

Like a person, a carnivorous dog may experience an abnormality in the digestive tract. And it is the digestion that suffers most often. This happens for one reason - improper feeding. Animals are given food from their table, as well as soups, borscht and liquid broths. This can not be done, the dog should eat, but not to lap, and in its diet should be 60% meat.

Diseases of the digestive tract can be very different, but they appear about the same. The dog refuses to eat, it becomes more selective. She has diarrhea or constipation. If this continues day after day, it is imperative to undergo an examination. At the same time review the diet, sometimes this is enough to improve the condition.

Liver disease in dogs

Symptoms will depend on the cause of the lesion, which will have to find out at the reception at the vet. The liver is a natural filter, it suffers for all diseases, for all toxic effects. And there comes a time when she is no longer able to cope with the load. The main symptoms of hepatopathy are:

  • dyspeptic syndrome: lethargy, depression, anorexia, vomiting, disorders of defecation,
  • jaundice: bradycardia, brown urine staining, light gray clay feces, icteric mucosal staining, pruritus,
  • hemorrhages in the skin and mucous membranes, anemia, an increase in bleeding time,
  • an increase in the abdomen in the epigastrium,
  • enlarged liver, simultaneous enlargement of the spleen.

Having found out the reason, the veterinarian will prescribe a complex treatment. It must necessarily include hepatoprotectors and sorbents.

Kidney disease

This is also not uncommon. Veterinarians note that every second dog that is brought to the reception has symptoms of kidney disease. In dogs, this is most often diagnosed at the age of 6 years. Impaired nutrition, infection, allergies, cooling and mechanical injury. The kidneys are adapted to splitting and excreting large amounts of animal protein. If an animal receives mostly porridge and other plant food, then this is a direct path to the development of urolithiasis in dogs. Symptoms are as follows:

  • Pain syndrome. This desire to sit or lie in one place. If you try to raise the animal, it arches the back of the arc. The dog often asks to go outside, and urination is painful.
  • Edema.
  • Cramps.
  • Apathy, anorexia and vomiting.

In the course of the diagnosis, the doctor determines what caused the problem, and proceeding from this builds a treatment regimen. Urolithiasis in dogs, whose symptoms will intensify without proper treatment, is primarily corrected by diet. Against this background, a course of antibiotics is required. The rest of the drugs at the discretion of the doctor.

Surgical diseases

This is the last, large group of ailments. These include diseases of the eyes and ears, teeth and muscles, and various injuries. At first glance, the symptoms are obvious. But in practice, everything is not so simple. For example, a clear limping on the front paw may indicate a pathology of the cardiovascular or musculoskeletal, and maybe the nervous system. Therefore, without a competent consultation again can not do.

Ear diseases

Symptoms of ear diseases in dogs are pronounced. There are lesions of the inner (otitis) and outer ear (hematoma). Most of the trouble is caused by inflammation in the inner ear. The animal shakes its head, while fluid or pus drips from the ear. It is swollen, there is redness. In this case, it is necessary to pass scraping for the presence of an animal ear tick. This microscopic creation often causes otitis.

Symptoms of ear disease in dogs are too pronounced to be ignored. The animal may have a fever, it whines and presses his sore ear to the floor. In this case, the treatment is not too complicated and costly. The doctor will diagnose and prescribe anti-inflammatory drops, tell you how to clean your ear. If inflammation is severely neglected, a course of antibiotics may be required. Otitis, which arose against the background of an allergic reaction, deserve special attention. Correction diet is required. The chicken, buckwheat is excluded, the diet is analyzed.

Eye disease

In dogs, they are quite common. Fortunately, they are easy to diagnose, and they are quite well treatable. Veterinarians have noted several cases with which pet owners most often address them:

  • Inversion and eversion century. Causes can be injuries and inflammatory processes. It is usually enough to remove the inflammation, and the eye returns to normal. But sometimes you have to resort to surgery.
  • Conjunctivitis. One of the most common diseases in dogs. Causes can be injury, foreign bodies. This is one of the most common symptoms of infectious diseases such as plague. In any case, you need to establish the cause and eliminate it. After that, you can do the symptoms themselves, that is, the discharge from the eyes. For this, decoctions of medicinal plants are used, as well as special preparations like drops of chloramphenicol.
  • Inflammation of the cornea. In this case, the animal almost can not open the eye because it is in pain. Do not pull with a call to the doctor. He will prescribe an antibiotic in drops, which will quickly bring the state of the organs of vision in order.

Instead of conclusion

To consider all the diseases of dogs and their treatment methods, ten articles are not enough. But we did not pursue the goal of creating an encyclopedia. The article states the most important thing that a loving owner should know. If your pet has strange symptoms, but it is cheerful and cheerful, eats its portion and plays, then you can just watch. If the dog is lying, refuses to eat and water, then do not expect a miracle. It is necessary to urgently consult a doctor.

Today, veterinarians have dozens of ways to treat the most difficult diseases. And nevertheless, many animals continue to die due to the fact that their owners just ask for help late.

Diseases of dogs by symptoms:

  • Increased thirst.

If increased fluid intake is not associated with high temperature in the room or excessively over-salted food, thirst can be a sign of increased levels of toxins in the body or endocrine disruption. Another serious disease in which this symptom occurs is renal failure, leading to severe lesions of the urinary system and even the death of a pet. In any case, if the thirst did not pass within a day or two, we advise you to immediately show the dog to the vet.

  • Frequent urination.

Often, increased thirst is accompanied by frequent urination. Ignoring this symptom is difficult, but most owners do not consider it a sign of a serious illness. In fact, this phenomenon may be a sign of cystitis (if the urge is frequent, and the amount of urine given off is insignificant) or urinary incontinence.

  • Pallor or even cyanosis of the mucous membranes.

Such a symptom, as a rule, is accompanied by weakness and the appearance of a staggering gait. If at the same time you notice that your dog's stomach is increasing in volume - without losing a minute, go to the vet. All these are signs of severe internal bleeding, which can be spent on a watch for life.

    Lack of appetite.

Here is a really serious symptom for the responsible owner. The first thing to do if a dog refuses to eat is to examine the animal's body in search of a tick, because lack of appetite and lethargy are among the first signs of piroplasmosis. However, even if you do not find the parasite, you should not relax - carefully watch the dog and, noticing other signs of ill health, immediately rush to the doctor. For the sake of justice, it must be said that our beloved pets often refuse food, even being completely healthy. It is possible that the dog simply decided to arrange a fasting day.

    Increased appetite, accompanied by a sharp emaciation of the animal.

It may be a sign of diabetes or worms invasion. In the first case, the pet needs carefully calculated insulin therapy, and in the second you have to rid it of internal parasites.

  • Hair loss throughout the body and the appearance of coarse dandruff.

These symptoms of demodicosis can also be accompanied by itching and general nervousness of the dog. Having noticed one or several similar signs, hand over a deep scraping from the pet's skin to the veterinary laboratory - the treatment directly depends on the type and number of demodectic mites that hit the dog.

  • Frequent urge to vomit and loose stools, especially on an empty stomach.

Often, the owners do not pay attention to vomiting and diarrhea, justifying this by the banal overeating or ingestion of not quite fresh food. In fact, such symptoms, repeated with enviable regularity, most often indicate such severe lesions of the digestive system as gastritis, pancreatitis or cholecystitis. Despite the fact that the instant death of your pet is not threatened, it would be nice to see a doctor as soon as possible and prescribe treatment with the help of enzymes.

  • Increased salivation.

Enhanced saliva secretion can be observed with sun or heat stroke, as well as injuries of the tongue and mouth. Another reason for this phenomenon is the ingestion of a foreign body into the dog's stomach - in this case, frequent regurgitation of freshly eaten food and water is also present.

  • Inflammation of the mucous membrane of the eyes.

In addition to contact with a foreign body or a staph infection, eye inflammation may be a sign of liver disease or gallbladder pathologies. If all sorts of eye treatments do not work, try looking at the liver counts in the tests and, if necessary, start treating this vital organ.

In addition to the expected bruise or fracture, the dog may limp in such an insidious and inconspicuous disease as arthritis. In this case, this symptom occurs in wet cold weather or in the case of a sharp overcooling of the animal. If your four-legged friend runs, joining the hind legs together like a hare, this is a clear symptom of hip dysplasia, an incurable hereditary disease that needs lifelong therapy.

  • Cough and impaired respiratory function, especially in an elderly dog.

Such symptoms signal acute or chronic heart failure, as well as fluid accumulation in the chest.

  • Purulent discharge from the loop.

Most owners know how dangerous pyometra is - purulent inflammation of the uterus in dogs. And that the first sign of this disease are purulent discharge from the vagina in a bitch. However, few people are able to notice such a symptom in time, paying little attention to what is being done under the tail of a beloved dog.

  • The animal behaves restlessly at night, whining, or walking in circles around the room.

Such signs are not at all a whim, but rather well-known symptoms of increased intracranial pressure. It can be observed after epileptic seizures, trauma or in case of problems with the heart or vessels. You can diagnose this condition with a CT scan or an MRI scan performed at all major veterinary clinics.

    Unnatural posture of a dog during rest.

An animal that does not bother, rests, as well as moves, naturally. The dog sleeps, curled up in a tight tangle, when it is cold and stretches the limbs in a warm room. In any pain syndrome, the animal takes a forced posture in which the pain is reduced and the unpleasant symptoms disappear. Having noticed that your pet is sleeping or not going as it used to be, be sure to show it to the vet, perhaps something is very disturbing.

  • Yellowness of mucous membranes and skin.

This symptom is difficult to notice, especially on black suit animals. However, the attentive owner will pay attention, then the sclera of the eyes and gums of the pet acquired an unhealthy yellowish color. Most often, such jaundice is provoked by liver diseases, up to cirrhosis, so do not delay the visit to the vet. However, a similar sign may occur for quite an innocent reason. The yellowness of the skin of the animal may indicate an excess of carotene in the body. Of course, any hypervitaminosis is unpleasant and requires correction of nutrition, however, compared to cirrhosis, it is quite innocent.

  • Pica.

A dog devouring any inedible objects is often provoked not by a lack of upbringing, as some people think, but by serious health problems. Most likely your pet is disturbed by digestive disorders, however, the perverted appetite can be a sign of more serious diseases - for example, rabies.

Most of the above symptoms may well have a harmless nature, not being signs of serious diseases. However, the health of your beloved pet is not a topic for guessing or hoping for. Seeing any of them or feeling that the dog's behavior has changed - immediately show it to the doctor. Even if the alarm was false, you will get rid of anxiety, and the slightest unpleasant surprise will not take you by surprise.
