Dermatitis in dogs

Dermatitis in dogs is a common occurrence. He is subject to animals, regardless of the degree of care and place of residence. Dermatitis is most often observed in some breeds of dogs - shar-pei, Dalmatians , Bulldogs, Rottweilers. The disease leads to a deterioration in the appearance of the animal, anxiety, exhaustion, severe lesions not only of the epidermis, but also of the dermis.

Dermatitis in dogs

Dermatitis is an inflammatory disease of the surface and deep layers of the skin. Depending on the causes of the disease, dermatitis is divided into:

  • mechanical;
  • contact;
  • medicamentous;
  • parasitic;
  • thermal;
  • allergic;
  • infectious;
  • paranormal.

Mechanical or traumatic dermatitis, which is considered to be the easiest in treatment, occurs at the site of injuries, scratching, cuts. Strong belt tightening or short haircut can lead to traumatic dermatitis, especially in poodles. Penetration through the injured surface of the skin of pathogenic microorganisms causes inflammation, swelling and reddening of the skin.

The contact form appears with a permanent traumatic contact of the animal's skin with a physical or chemical irritant. It can cause, for example, a collar, the dog's habit of leaning against radiators, contact with aggressive chemicals.

At living in city apartments of dogs it can cause washing-up liquids, cosmetics, means of disinfection etc. These types of exposure cause the appearance of vesicles, swelling, reddening of the skin, drying out and ulceration of the epidermis.

Medicated dermatitis occurs in response to the action of medications - iodine, ointments, antiseptic agents. With prolonged exposure to dressings with liniment, for example, can lead to irritation and then to dermatosis.

The consequences of the effects of drugs on dogs can be very serious. Pathology can be accompanied by allergic reactions and lead to allergic dermatitis, vesicles and papules appear, wet sores, areas of hyperemic and swollen skin. Itching is rare, but sometimes it can be quite pronounced.

Parasitic dermatitis is caused by parasitic insects - fleas , mites . A large number of fleas in the skin of an animal leads to the appearance of not only an itch from bites, but also an allergic reaction to the products of the life of fleas.

Parasitic invasions cause scratching, which are inseminated by pathogens, edema and flushing of tissues. Gnawing the course to the sebaceous glands, the mite damages the follicle and hair dies. When ticks are infected, focal abaissement of the coat is observed. Parasites carry some types of helminths, a decrease in immunity and damage to internal organs, especially muscles, intestines, cause abnormalities in the skin and, as a result, dermatitis.

Thermal dermatosis occurs in response to a thermal or radiation exposure. Burns caused by high temperature (fire), X-ray, microwave or ultraviolet radiation, cause inflammatory reactions, the appearance of wounds. The same consequences are observed due to the effect of low temperatures - frostbite.

Allergic dermatitis causes allergenic substances - pollen, dyes, preservatives in poor-quality feed, detergents, etc. The most complex in the treatment of atopic dermatitis in dogs, which is autoimmune in nature and genetically conditioned, belongs to this species. Allergic dermatitis is difficult to diagnose, because its symptoms are similar to a number of diseases.

Infectious form of dermatitis is caused by various pathogens - fungi, bacteria, viruses, etc. The most common form of infectious dermatitis is staphylococcal dermatitis (pyoderma). Reduced barrier functions of the skin in dogs provoke infection with mycobacteria, streptococci, actinomycetes. Light forms of superficial skin damage cause itching, exudation, superficial erosion.

Peripheral dermatitis - a reaction to the long-term effects of purulent discharge from the wound. As a result of maceration of the skin on it appear areas with fallen hair, erosion, swelling in the upper layers and subcutaneous tissue. As a result, the skin coarsens, it forms folds and peeling of the epidermis.

The listed types of dermatitis in dogs have many variations - dermatitis food, endocrine, neurogenic, etc. Each species has its own characteristic symptoms, but there are a number of common manifestations that indicate the presence of dermatosis.

Symptoms of dermatosis in dogs

Symptoms of dermatitis in dogs

Common symptoms include such manifestations as:

  • local increase in temperature in the lesion;
  • hyperemia of the skin area;
  • violation of the hairline (total or local alopecia);
  • bleeding from small vessels, resulting in crusts of coagulated blood;
  • soreness in the affected area;
  • itching;
  • sweating exudate into injured tissue and edema formation;
  • joining the inflammatory process in the skin tissues;
  • ulceration of the skin surface and the passage of pathology into the dermis.

As a result of the progression of the pathology, the dog becomes restless, the body is exhausted, there is a lack of appetite, a violation of sleep. Timely begun and correctly selected treatment gives a positive result and has a favorable prognosis of the outcome of the disease.

To clarify the diagnosis and the appointment of an effective treatment, you need to contact the veterinarian for the first symptoms of the disease. Do not self-medicate, so as not to aggravate the situation by an allergic reaction to medications.

Methods for diagnosing dermatitis

Methods for diagnosing dermatitis in dogs

From the correct diagnosis of the disease depends the success of treatment and outcome. Since many types of diseases in dogs have similar symptoms, only thorough, comprehensive studies can provide an objective picture of the causes of the disease. For the statement of the exact diagnosis appoint:

  • laboratory studies of the type of adherent infection and concomitant diseases;
  • bacteriological culture and microscopic examination of skin scrapings;
  • the sensitivity of the infectious agent to antibiotics ;
  • a study of blood samples for eosinophils and leukocytes;
  • analysis of blood and urine;
  • coprogramme.

Once an accurate diagnosis is established, an individual scheme is developed that includes a complex effect.

Dermatitis in dogs

The treatment regimen for dermatitis depends on the type and cause of the pathology. Therefore, only an experienced veterinarian can determine the true cause of dermatitis. For treatment is appointed:

  • drug therapy;
  • physiotherapy.

At the beginning of treatment, the wool on the affected area is cut to facilitate access to the lesion site. With the help of an antiseptic solution, remove necrotic tissue, exudate, bloody crusts. Place powdered with an antiseptic powder. Locally used bandages with medicinal ointments to accelerate the regeneration of tissues, antibacterial, antifungal, anti-inflammatory, etc. Apply applications of paraffin, ozocerite. To stop the pain, Novocain blockades are prescribed.

Medication therapy includes:

  • Course use of antibiotics in connection with secondary infection or infectious dermatitis. Antibiotics from groups of penicillins, cephalosporins, carbapenems, etc. are prescribed. The treatment is carried out strictly according to the intended purpose, with observance of the dosage and course of administration. With the simultaneous use of systemic antibiotics and ointments, the treatment of dermatitis occurs in a short time.
  • When fungal skin lesions require the use of fungicidal drugs, for example Fungin, Zoomikol, etc. Apply treatment with fungicidal shampoos - Nizoral, Clotrimazole, Ketoconazole, etc. If no pronounced effect is observed, autohemotherapy is prescribed.
  • Antihistamines are used to relieve itching and allergic reactions. For the treatment of dogs, Suprastin, Tavegil, Dimedrol, Fenistil, and others are used. A special anti-allergenic drug Allerveth is also used for animal therapy.
  • Detoxification of the body is carried out by the reception of furasemide.
  • To boost immunity, immunostimulants can be used that affect the increase in T cell activity, for example, Gamavit, Gamaprene, Glycopin, Immunol Vet, and others.
  • To destroy the parasitic component, various insecticidemic acaricides are used, for example, Prach-tic, Sanofly, Spot-on, Scalibor, etc.

Physiotherapy in the treatment of dermatitis in dogs uses irradiation of the wound surface with ultraviolet lamps, for example, Sollux or infrared lamps. Irradiation promotes the acceleration of tissue regeneration, has an antibacterial effect, helps reduce purulent and serous discharge, activate phagocytic functions of cells. The use of physiotherapy should be prescribed by a veterinarian, since the method has contraindications.

With timely started and adequate treatment, the prognosis for dermatitis in dogs is positive in 90% of cases.
