Hypodermis includes a wide range of infections that result in the formation of pus. Pyodermas vary in severity. Treatment is similar to that for hot spots, but typically is longer term. Shampoos and rinses are also helpful. Atopy is a very itchy skin disease, which is the result of allergies to microscopic particles in the air.
Diagnosis is based on clinical presentation and absence of other causes such as ectoparasites.
Treatment includes dietary supplements, antihistamines and steroids, and is often long term. In very refractory cases skin allergin testing and hyposensitization may be helpful. Shampoos and rinses are also often helpful. These parasites break the barrier formed by the skin and allow bacterial infections to occur. They may lead to allergic conditions.
