Is Yeast Infection in Dogs Ears Contagious?

Yeast infection only occurs when there is an overgrowth of yeast in the ear or other parts of a dog. This overgrowth is facilitated by the presence of an ideal environment such as when the pH level is disturbed or when there is increased moisture among other causes.

What Causes Yeast Infection in Dogs Ears? – Causes of Dog Ear Yeast Infections

Yeast infections develop when there is a conducive environment for their proliferation. When this happens, the yeast growth becomes uncontrollable and leads to infections. Some of its causes are as discussed below.

Excessive Use of Antibiotics

The Malassezia fungus which is what causes yeast infections is usually kept in check by another species of bacteria. When your dog is subjected to antibiotic treatment, it kills off the friendly bacteria allowing for the Malassezia fungus to multiply and grow out of control. As such, a bout of yeast infection could be caused by excessive use antibiotics.

Weakened Immune System

Like with any other infection, dogs with a strong immune system have the ability to fight off yeast infections. However, when their immunity is compromised, yeast grows uncontrollably. To increase their chances of fighting off yeast and other infections, ensure they remain healthy.


Ears that have been wounded or suffered scratches are more susceptible to yeast infections than those that are without damage. Where they suffer these, try to keep your dog’s wounds cleaned up and free of moisture. This will help in quick healing as well as prevent yeast infections from occurring.

Ideal Environment

Yeast thrives in areas of the body that is dark, moist and warm. These are conditions prevalent in the ears and the reason why floppy eared dogs are more vulnerable to yeast infections in the ears. To prevent them from getting infected, regularly clean up their ears by wiping them using wet wipes.

Presence of Water in the Ear

This mostly happens after the dog has had a dip. A dog’s ear canal structure is such that once water gets in, it is hard to get it out. When this happens and water remains in the ear canal, it offers an environment that encourages the proliferation of yeast. When this is sustained for a while, infections in the ear occur. To avoid this, dry up your pet’s ears after they have had a swim.
