What Are the Causes of Yeast Infections in Dogs' Ears?

Ear infections are one of the most common ailments veterinarians see in dogs, and yeast is a frequent culprit. By knowing what causes a yeast infection to grow in your dog's ear, you can help prevent this uncomfortable condition.

  1. Moist Conditions

    • Yeast thrives in dark, moist areas, and a dog's ears provide the perfect environment. Dogs with long, floppy ears are especially prone to yeast infections, though those with ears that stand up can also suffer from them. Accordingly, keep your dog's ears clean and dry to help prevent infections from starting.

    Grain Allergies

    • Grain allergies can also manifest themselves as yeast infections in the ears and other places on a dog's body. This can be remedied by switching the dog to a grain-free or raw diet. This solves the problem of recurring yeast infections for many dogs.

    Antibiotics

    • Often, antibiotics can change your dog's pH balance and cause a yeast infection as well. If your dog is currently on another medication, consult with your vet for the best course of action to make your dog as comfortable and healthy as possible.

    Ear Mites

    • Ear mites may be responsible for causing the problem. Some dogs develop ear infections as a reaction to ear mites.

    Endocrine System Problems

    • Very rarely, endocrine system problems can be responsible. If yeast infections are recurring even after a thorough cleaning and changing your dog's diet, it could stem from the endocrine system.
