Can Dog Food Cause Ear Yeast Infections

What Causes Yeast Infections

Ask A Veterinarian: Pet Allergies Tied to Skin & Ear Infections

Yeast infections usually occur secondary to other issues. Yeasts are found in low numbers on normal dogs in places like the ear canals and lip margins, usually causing no issues.

But in a dog that has an underlying skin condition, these yeasts are given optimum conditions in which to multiply. The most common yeast infection in dogs is known as Malassezia dermatitis caused by a yeast called Malassezia pachydermatis.

The types of underlying conditions that can predispose a dog to secondary yeast infections include:

Yeast Infections In Dogs: Symptoms And Treatment

In low numbers, yeast in dogs is considered normal. Yeast is commonly an inhabitant of a dogs skin and ears. Every dog will carry a few yeast around with them, but if there is a problem with the immune system, if a dog has wet ears, ear mites or excessively long ear canals, or if a dog has skin allergies, then the yeast can grow out of control and cause problems.

Yeast Overgrowth Is The Enemy

Yeast naturally resides in the environment or microbiome of the ears and skin. Certain factors in your pets microbiome help regulate yeast growth to create a healthy balance in the ear. But that balance can be disrupted when underlying factors cause inflammation in the ear. Inflammation can then cause swelling and the glands to over-secrete. This process leads to a moist environment in the ear canal. And because yeast thrives in a dark, moist environment, yeast overgrowth ensues. Overgrowth leads to dark brown discharge, an unpleasant odor and scratching at the ears.

Common Allergy Triggers In Commercial Dog Food

Thanks to science, nutritionists and researchers have uncovered the main offenders in dog food. Lets go over each one.


Protein is, unfortunately, a common allergy trigger for allergy sufferers particularly frequently seen in meat like chicken, beef, and fish.

Often, hydrolyzed or aid in digestion and nourish the body. Novel proteins use a new protein source that has never been introduced to your dogs system before. Hydrolyzed proteins are broken down to microscopic bits so they can essentially bypass the system.


Dairy, more specifically, lactose, is another huge trigger for dogs. A big telltale sign that your dog has a dairy allergy is itchy skin and rashes. Believe it or not, there is a difference between lactose allergy and lactose intolerance.

Lactose intolerance is linked more to gastrointestinal upset versus skin irritation. So, if dairy is causing recurring ear infections, it is usually linked more to the allergy than the intolerance.


Gluten is not nearly as triggering as dog food companies would lead you to believe. In fact, it makes up only a small percentage of dog food allergies total. But rather than ear infections, gluten allergies usually present with diarrhea, loose stool, mucous in stool, gas, and other gastrointestinal symptoms.

Just because these are the most prevalent allergy triggers, it doesnt mean they are the only ones. Dogs, like us, can be allergic to just about anything.
