Purulent skin lesions in dogs, or pyoderma, are ubiquitous. Subject animals of all breeds. However, such breeds are most prone to pyoderma: Shar Pei, Mastino Neapolitano, Bullmastiff, Chow Chow Boxer, Pug, Chihua Hua, English Bulldog, French Bulldog. Pyoderma in dogs – skin disease in the form of pus accumulation. When the surface form affects the outer layers and hair follicles. The deep form of pyoderma is characterized by skin lesions throughout the entire thickness. Sometimes hypodermic cellulose and muscles are affected.
Pyoderma in dogs – causes and development
Pyoderma is caused by several reasons. The main reduction is considered immunity. The fall of the body’s defenses occurs as a result of changing conditions of detention, feeding or movement. For example, the dog was constantly kept in the room (apartment or house) and sent to live on the street. Or a dog, who constantly lived in the yard of a private house, is taken to live in an apartment. Changing the feed affects the immune system, not only with a decrease in calories. The main source of antibodies, protein, the dog gets from the meat. For the sake of economy, meat is often replaced by offal and entrails. Such a replacement, even while maintaining the energy value of the feed, reduces the nutritional value and cannot meet the needs of the dog. The ratio of meat, by-products and slaughterhouse waste, croup recommended for the breed should be adhered to.
The transfer of adult dogs to dry or canned food exacerbates a number of chronic diseases that reduce immunity. After about one and a half – two months, these processes return to normal. Immunity is fully restored 4 months after switching to dry food.
It is necessary to take into account the ratio of movement and feeding. So, during training, the dog requires more food by about 15 – 20%. During intensive work, needs increase up to 40%.
Lack of movement for dogs is just as harmful as excess. With a lack of movement, the skin does not clean itself. Dust, dead skin, various discharges serving as food for germs accumulate in wool.
A secondary cause of pyoderma is considered a violation of the integrity of the skin. So, running in the fall through the meadows, puppies often hurt the skin of the abdomen on dry grass. Short hair of bulldogs, bullmastiffs and sharpei scratches the skin in the folds.
Worms, fleas and microscopic mites promote the development of pyoderma. The presence of parasites reduces immunity. In addition, fleas and microscopic mites damage the skin. The skin in the folds of the muzzle is particularly susceptible to pyoderma (in bulldogs and similar breeds), near the genitals and in the abdomen (in large breed puppies).
Pyoderma in dogs – symptoms
In the place of injury, microbes rush instantly, normally living in the dog’s body. If the paw is affected, fungi from the soil also enter the wound. After 3 – 5 days after getting into the wound, microorganisms begin to multiply rapidly and acquire pathogenic properties, the skin becomes inflamed. There is severe itching. Combing the affected areas, the dog rubs the microorganisms in the hair follicles. Claws scratch the skin, microbes settle in the hairs.
Without qualified help, the abscesses unite in large cavities, slowly poisoning the dog with contents. There is a strong itch. Combing the affected areas, the dog rubs the microorganisms in the hair follicles.
A few days after the appearance of severe itching, red and yellowish blisters are visible on the skin. When piercing from them liquid with an unpleasant smell is emitted. Over time, the dog falls wool. The affected areas go bald, bubbles merge into shapeless areas. When the animals itch, the blisters can break open, spreading unpleasant odors and germs. This is the manifestation of the surface form of pyoderma.
After a few days, the pus eats away the layers of skin under the hair follicles. Together with the current of pus, microbes settle in the lower layers of the skin.
The body of a sick dog tries to respond to the development of microbes. The production of antibodies is increasing, macrophages are being sent to the places of microbial development. But to cope with an infection in the skin of the dog’s body can not. Microbes spread throughout the body and can cause inflammation of various organs. Over time, the pustules merge into large boils that can open at any point on the dog’s skin. Purulent fistulas appear, in large dogs up to 7 cm deep. This is how the deep form of pyoderma is manifested.
The disease can last for years; without qualified help, the abscesses unite in large cavities, slowly poisoning the dog with contents.
Pyoderma in dogs – treatment
It is carried out only in the conditions of a veterinary clinic. Symptoms, similar to pyoderma, appear in completely different diseases. For example, distemper, ingestion of extraintestinal worms dirofilaria. Purulent skin lesions are complicated by the attack of microscopic mites, such as demodicosis.
