Canine Ear Infections
How common are ear infections in dogs?
Infection of the external ear canal by bacteria or yeast are one of the most common types of infections seen in dogs. We call this otitis externa.
Some breeds, such as Cocker Spaniels and Miniature Poodles, seem more prone to ear infections, but they may occur in any breed.
What are the symptoms of an ear infection?
A dog with an ear infection is uncomfortable, its ear canals are sensitive. It shakes its head trying to get the debris and fluid out, and it scratches its ears. The ears often become red and inflamed and develop an offensive odor. A black or yellowish discharge commonly occurs.
Don’t these symptoms usually suggest ear mites?
Ear mites can cause several of these symptoms, including a black discharge, scratching and head shaking. However, ear mite infections generally occur most commonly in puppies. Ear mites in adult dogs occur most frequently after a puppy carrying mites is introduced into the household. Sometimes ear mites will create an environment within the ear canal which leads to a secondary infection with bacteria and yeast (fungus). By the time the dog is presented to the veterinarian , the mites may be gone, but a significant ear infection remains.
