There are three main types of allergies that we see.

Environmental allergies or Atopy, Food Allergy, and Flea bite hypersensitivity.

All of these can appear the same on examination.  It is important to mention also that a pet that has one type of allergy may also have another.  Sometimes if you control the biggest portion of the allergy, the other allergic components are not as much of a problem.  

Allergies in dogs and cats cannot be cured.  Our goal is to control the allergy, minimize the signs, and use as few medications as possible to keep your pet comfortable.
