What Causes a Yeast Infection in a Dog's Ears?

Dogs have very expressive ears.

Those wonderful, expressive ears on your best canine friend can harbor a stinky and painful yeast infection. Everything from genetics, injury, swimming and allergies can contribute to yeast infections, but the good news is that they can be prevented.

Floppy Ears

Floppy ears create a perfect environment to grow yeast.

Long, floppy ears look adorable, but they also provide a perfect environment for yeast to grow. Reduce the darkness and moistness by occasionally flipping the ear over and allowing it to breathe. Regular use of an ear cleaner from may help, too.

Ear Canals

Ear plucking is an important part of getting groomed.

Groomers know that breeds like Shi Tzu, Poodles and Cockers need their ears plucked to prevent hairs clogging the canal which can lead to yeast infections. If you groom your dog yourself, make sure to get ear powder and learn to pluck your dog's ears.

Water

Wet ears can get yeast infections.

Wet ears are prime targets for yeast infections. After you've bathed your dog or he's gone swimming or run around in the rain, make sure the ears are completely dry or that you use a prescribed drying product.

Allergies

Allergies to food can cause yeast infections.

Allergies are often the culprit when you see repeat yeast infections. Your vet may recommend switching to a hypoallergenic dog food.

Injuries

An injured ear can get a yeast infection.

Scratches or injuries in the ear can upset the delicate balance and lead to a yeast infection.
