Dog Ear Yeast Infection

Dog Ear Yeast InfectionsDogs with normal ears that appear healthy and clean are proof that the ear environment is well maintained under control by bacteria. However, if for some reason or another, the dog’s system is disrupted, bacteria may no longer be able to protect the ears from invaders, therefore, yeast may take over the battle and begin to proliferate. This is when trouble begins.

But what is really Yeast? What causes the yeast to proliferate in first place? Why bacteria were no longer able to keep yeast under control?

     What is Yeast?

Yeasts are single cell forms of fungi that resemble spores. They are naturally found on skin and ears in small amounts.

     Causes of Dog Ear Yeast Infection

  • Antibiotics

One of the most common causes of yeast infections is a prescription for antibiotics. Antibiotics are well known to kill both good and bad bacteria in the gut, and this is why yogurt is often prescribed. However, antibiotics can also kill the good bacteria in the ear as well.

  • Weakened Immune System

Dogs that are stressed or weakened because fighting against a disease, are more likely to develop yeast infections in their ears. A good way to prevent these annoying infections is therefore to ensure your dog is fed premium dog food (many claim raw food is the best way to go) gets sufficient exercise and lives stress free.

  • Weakened Ear Environment

If your dog’s ears are already bothering the dog because of allergies, the constant scratching and the higher production of oils, may open the way to yeast growth. So a dog may have ear problems such as a bacterial infection and an ear yeast infection on top of that because the skin in the ears has become vulnerable.

  • Ideal Environment

Yeast thrives in humid, dark and warm areas, therefore, your dog’s ears make yeast a perfect place to live and settle causing those annoying ear yeast infections in dogs. This is mostly seen in floppy ear dogs that because of their conformation it is easy for yeast to settle in and thrive. Dogs with erect ears therefore, may be less likely to get ear yeast problems because their ears are naturally more likely to be exposed to light and air.

     Dog Ear Yeast Infection Symptoms

A dog affected by a yeast infection in its ears is very likely prone to be quite miserables. Symptoms of ear yeast infection in dogs may be as follows:

  • Head Shaking
  • Pawing at Ears
  • Ear Scratching
  • Rubbing Ears
  • Swollen Ears Ear Discharge
  • Foul Smell


Ideally, the dog should have a veterinarian check the ears so to exclude other ear problems. If the ears have a black coffee ground discharge there may be actually ear mites, which require a totally different treatment than yeast.

The best way to diagnose a ear yeast infection is by having the vet collect a sample and view it under the microscope. In some cases, a culture and sensitivity test is recommended.

     Natural Home Remedies

  • Before using any home remedies the ear canal needs to be cleaned well. Medications or home remedies may not work in a dirty ear because they are unable to treat the surface of the skin directly.
  • One of the best home remedies for yeast infection in the ears is white vinegar. White vinegar is able to return the ear’s PH back to an acidic state that makes the yeast inhospitable for yeast. The vinegar should never be used in its pure form, rather it must be diluted. A 50/50 mix of white vinegar and water may be mixed well and poured in a spray bottle.
  • After the ears are clean, the solution should be sprayed in the ears and dried out with a cotton ball twice a day. Te ears should improve within 48 hours.
  • Over the counter ear solution Zymox is an effective product that relieves bacterial and yeast ear infections without side effects. There are many success stories on this product. If not the dog may need stronger prescription ear drops from the veterinarian.

     Special Precautions

  • Floppy ear dogs should never be left with their ears wet. If you are planning to bathe a floppy ear dog follow what groomers do: put cotton balls inside the ears to prevent them from getting wet.
