Yeast Infections in Dogs Ears

Though yeast infections can occur virtually anywhere on your dog, the anatomy of a dog’s ear  make the ears the place where conditions are most habitable for the yeast and that is where the infection frequently occurs. A dog’s ear plunges downwards and then curves away from the opening, with less airflow deeper in the ear canal.

An overgrowth of yeast which may or may not be linked to a fungal infection is what constitutes a yeast infection. If left untreated your dog will unfortunately develop other health problems.
