Ear Infections in Cats and Dogs

Animals affected

Cats and dogs of any age.

Overview

Ear infections are common and painful problems for pets. In cats and dogs, ear infections typically are opportunistic and not contagious. They often occur when the ear's immune system is disrupted by allergies, moisture, poor air circulation, or diseases such as feline AIDS. Under these conditions, bacteria and yeast that normally live harmlessly in the ear are able to proliferate to the point of infection.
