Parasites including ear mites are a common cause of ear infections in dogs. These super small organisms can spread to and live in your dog’s ear canal.

So can ear mites spread to other dogs?
Yes, ear mites are highly contagious and they can spread to other dogs in close contact. If you are wondering whether humans can catch ear mites from dogs & cats, you will be glad to know it is extremely rare.
Yeast & Bacterial infections
Dogs can get ear infections due to an overgrowth of yeast inside the ear. Several factors can lead to yeast infections, such as trapped water in the ear canal as a result of swimming or bathing. Lack of airflow can lead to creating wet & moist conditions inside the ear and this often results in causing a yeast infection. This is also the main reason large & floppy-eared dogs are more prone to ear infections.
Some of the other causes of yeast infections in dogs include:
- Immune system disorders
- Excessive ear cleaning

Fortunately, dog ear infections caused by yeast & bacteria are not contagious and cannot spread to other dogs or humans.
