Collies, Shelties and Dobermans may be predisposed. In this disease antibodies are produced against components of the basement membrane causing the formation of bulla and then deep ulcers. Clinical signs of BP are very similar to pemphigus vulgaris. Other areas of the body that may be affected include the groin and axillae. Animals may be febrile and anorectic.
Treatment includes the use of immunosuppressive doses of steroids and azathioprine.
Gold salts can be used. Prognosis is usually poor.
