American College of Veterinary Dermatology 

The American College of Veterinary Dermatology certifies veterinarians who have expertise and specialized training in the diagnosis and treatment of animals with benign and malignant disorders of the skin, mouth, hair ears and nails. A veterinary dermatologist also has had significant training and is experienced in the treatment of allergic disorders. Their extensive training and experience make dermatologists extremely qualified in the diagnosis and treatment of infectious and non-infectious skin diseases, parasitic skin diseases, autoimmune diseases, allergy and allergy-induced skin diseases, recognition of the skin manifestations of systemic disease (including internal malignancy), cancer of the skin, cysts and other tumors of the skin and chronic infections and inflammatory conditions of the ears. 

Veterinary dermatologists perform many specialized diagnostic procedures including microscopic examination of skin biopsy specimens, cytological smears, allergy tests, potassium hydroxide preparations, fungal cultures and other microbiologic examination of skin scrapings and secretions. Treatment methods used by dermatologists include externally applied, injected and internal medications and certain dermatologic surgical procedures including skin biopsy. The training and experience of dermatologists may include cryosurgery with the use of freezing surgical units, laser surgery, nail surgery, biopsy techniques and excisional surgery.
