Dog breeds that feature larger or floppy ears are more likely to develop a yeast infection than dog breeds with upright or erect ears. This is because floppy ears give yeast bacteria the ideal warm and dark environment for optimal growth.
-
Itching
-
One of the most common signs of any ear infection in a dog, including a yeast infection, is excessive itching of the ear.
Shaking
-
In addition to itching or scratching, the dog might also frequently shake its head in an attempt to dislodge or remove the source of the itch.
Ear Wax
-
There might be an increase in the amount of ear wax present in the canine ear. The ear wax might also appear to be a pink to brown color.
Odor
-
The yeast bacteria will produce a foul odor in the affected ear(s) of the dog.
Treatment
-
Before applying any medication, the dog's ear will be cleaned out using a gentle cleansing solution. Then an anti-fungal solution is applied to kill off the yeast. In the event a secondary bacterial infection has occurred, oral antibiotics might be prescribed.
