What should I do before my appointment with a dermatologist?
- We ask that you do not bathe your pet from the time you make your appointment until the time you see the dermatologist.
- If your pet is currently on a steroid such as prednisone, we’ll discuss possibly weaning them off the medication prior to the appointment. Steroids can mask some of the symptoms that can be helpful in reaching a diagnosis. Never discontinue steroids without consulting a veterinarian first.
- Please bring all medications that your pet is currently taking or has recently been on to your appointment. This includes your flea/tick and heartworm medication. If you can’t bring them with, please take pictures or write down the name, strength and dosage.
- If you have any questions, you can reach the dermatology department at dermatology@mvsvets.com.
