What to Expect

One of our senior veterinary students will take a complete patient history and perform an initial dermatologic examination on your pet under the supervision of a staff dermatologist. Please note, that as a matter of policy and because specialized equipment is not available in all consulting rooms, the examination is performed in the dermatology treatment room and you will be asked to return to the lobby during the examination. A staff dermatologist will then complete a thorough examination. Typically, routine minor diagnostic procedures (skin cytology and scrapings and ear cytology) will also be performed at this time. It is likely to be 40-60 minutes before the staff dermatologist will speak to you about diagnosis and treatment options. Please allow 1.5-3 hours for your initial visit to our service.

Our mission is to provide you with the best diagnostic and therapeutic plan that will help control or resolve your pet’s skin or ear disease.
