Yeast Infection in Dog’s Ears: Causes, Symptoms, and Treatments

Yeast infection in dog’s ears is a specific ear infection that develops when yeast species (Malassezia pachydermatis) that normally populate the dog’s ears overgrow. The overgrowth of yeasts leads to a disrupted balance of microorganisms in the ears, resulting in an ear infection.

The mentioned Malassezia pachydermatis is the most common cause of yeast infection in dog’s ears. In normal conditions, the yeast lives on the dog’s body – skin, skin folds, and ears in small numbers.

However, given the opportunity (warmth, moisture, weak immune system), it overgrows and causes outer ear infections (otitis externa) and skin infections (dermatitis).

What Causes Yeast Infections in Dog’s Ears?

Yeast infection in dog’s ears is caused by yeast overgrowth, which is a secondary problem. In simple words, there is an underlying condition that triggered the overgrowth of yeasts.

Here is a short review of some of the common underlying causes:

  • Other Ear Problems: Basically, all ear problems – from ear mites to ear hematomas can result in yeast overgrowth and ear infections.
  • Poor Ear Hygiene. Moisture and warmth support the growth of yeast. If the dog’s ears are left moist (after swimming or due to excessive grooming), they are likely to get infected. The same is true for leaving the hair inside the ear canals long and unkempt.
  • Skin Disease: Underlying diseases of the dog’s skin, like food allergies, atopic dermatitis, flea allergy dermatitis, and bacterial infections, can lead to yeast infections.
  • Hormonal Imbalances: Hormonal disorders (Cushing’s disease, hypothyroidism, or diabetes) can lead to yeast overgrowth.
  • Weakened Immune System: A dog’s immune system can be weakened by infectious disease and immune-suppressive medications.

Yeast infection in dog’s ears is more common in dog breeds with floppy ears (like Cocker Spaniels and Basset Hounds) and dogs with hairy ear canals (like Poodles).

What Are the Symptoms of a Yeast Infections in Dog’s Ears?

Symptoms of a yeast infection in dog’s ears include:

  • Ear Odor: Yeasts produce an unusual smell which gives the dog’s ears a bad and musty odor. In severe cases, the entire dog may smell musty.
  • Ear Discharge: The buildup of yellow, brown, or black waxy discharge is likely in dogs with yeast infections.
  • Ear Scratching: Yeast infections cause itchy ears and make the dog scratch them or at least paw at the ears.
  • Painful Ears: A dog with a yeast infection can develop painful ears. Touching the ears may make the dog irritated or even aggressive.
  • Head-Shaking: Excessive head-shaking due to discomfort can be a sign of yeast infection in the ears.
  • Hair Loss: Due to excessive scratching and self-trauma, the hair around the base of the ears can fall out, and the skin can be flaky, crusty, or simply irritated.
  • Loss of Balance: If the ear infection spreads and affects the inner ear, the dog may show loss of balance and disorientation.
  • Hearing Loss: In rare and very severe cases, an untreated yeast infection in dog’s ears may result in partial or complete hearing loss.

How Do You Cure Dog Ear Yeast Infection?

Treating a yeast infection in dog’s ears requires topical antifungals (drops and ointments). The most common active ingredients in these meds are ketoconazole and miconazole. Plus, some antifungal drops and ointments will contain anti-inflammatory medications. In more severe cases, the vet can also prescribe oral antifungals.

In conjunction with these antifungals, the vet may suggest using ear cleaners that will remove the ear wax buildup and allow the medication to reach the lining of the dog’s ear canal.

Either way, when dealing with a yeast infection, it is important to see a vet. The vet will examine the dog (using an otoscope), establish a diagnosis, and recommend a treatment plan.

If your dog is prone to ear yeast infections, it is advisable to get anti-yeast dog food. This dog food is specifically formulated to keep the yeast population in check and prevent their overgrowth.

Will Dog Ear Yeast Infection Go Away on its Own?

It is unlikely for yeast infection in dog’s ears to go away on its own.

In most cases, it takes between 4 and 6 for the infection to clear, with treatment. Based on the severity, the vet may recommend cleaning the dog’s ear canal. Then, they will probably prescribe your dog medications or suggest using specific over-the-counter ear cleaners.
