How Do Dogs Get Ear Infections
There are many causes of ear infections in dogs, but theyre commonly due to bacteria and yeast. These organisms typically live on the surface of normal skin in the ear canal without causing a problem. However, a change in the environment of the ear canal or ongoing inflammation can allow these organisms to overgrow, leading to infection.
Allergies are the most common underlying cause of ear infections in dogs. They often lead to excess wax production in the ear, creating a moist environment that is perfect for bacteria and yeast overgrowth. Excess moisture can also occur due to residual water in the canals after swimming or bathing. Foreign material, ear mites, and excess hair growth in the ear canal are less common causes of infection in dogs.
Ear infections are much more common in dogs than in humans due to the unique shape of the canine ear canal. No matter what the outside of the ear looks like, all dogs have a vertical and horizontal ear canal. These two canals form a J shape, making it harder for wax, water, and debris to exit the canal, resulting in increased moisture and irritation. Because this condition is caused by an overgrowth of the normal bacteria and yeast in your dogs ear canal, ear infections are not contagious between dogs or other pets.

- Crusting on the ear flap
- Excessive scratching at one or both ears
