Dermatology involves the diagnosis and treatment of skin and ear diseases. Some of the problems that may bring patients to us include allergies (usually present as itching, scratching, licking, or chewing), skin diseases caused by parasites (fleas, ticks, or mange mites), and bacterial or fungal infections of the skin and ears. Hair loss, some skin cancers, and abnormalities of the foot pads and nails are also treated by dermatologists. Dawn B. Logas, D.V.M.
