Pet Ear Infections

Ear infections are very common in dogs and cats. They are some of the most common conditions we see in veterinary medicine. Ear infections cause redness and swelling and can lead to damage to the ear canal, hearing loss, and other problems; they also hurt!

Have you noticed your dog scratching at his ears or shaking his head? Is he or she rubbing his head on the carpet? These are all common signs your pet has an ear infection. In the following article, I will discuss ear infections in dogs and cats and how they are diagnosed and treated.

Ear infections in our dogs and cats tend to have certain characteristic signs. Redness, pain, and discharge are common. As mentioned above, rubbing their ears on the carpet, shaking their heads, or scratching at the ears are all common signs of an ear infection. Pets may also have a bad odor coming from one or both ears.

While ear infections are very common, they are never normal. There is always an underlying issue that causes the ear infection. There are many primary causes, secondary causes, and perpetuating factors.

These include allergies, both from environmental factors and food (atopy), hypothyroid or other endocrine disorders, ear mites, foreign bodies in the ear canal, excess wax or debris in the ears, and water or moisture in the ears. Certain auto-immune or primary skin diseases can also result in ear infections.

While treating an ear infection may seem fairly straightforward, finding the ear infection cause is the key to preventing it from returning. Dogs with allergic skin disease can take medications to help control their allergy, and food trials can be performed if an underlying food allergy is suspected.

Additional testing is also recommended when appropriate to help identify any underlying endocrine disease which may be contributing to the ear infection. Finally, evaluation with an otoscope will allow your veterinarian to check the eardrum to ensure it is intact and no evidence of inner ear disease is present.

After obtaining a history and a thorough physical examination, a sample will likely be taken from your pet’s ear and stained before being placed under a microscope. Your veterinarian will look for bacteria, yeast, and cellularity to determine what medications are most likely to be successful in treating the infection.

In many cases, a liquid flush and an ointment will be dispensed, which will help remove excess debris from the ears, eliminate yeast and bacteria, and reduce the pain caused by infection. Which medications are appropriate depends to a large degree on what your veterinarian sees under a microscope.

It is crucial to clear the ear infection completely. Your veterinarian may recommend a re-check examination to look at another sample following treatment to ensure the entire infection is no longer present. Partially clearing an infection can result in repeated ear infections, leading to more resistant, difficult-to-eliminate bacteria.
