Repeated head shaking. Foul-smelling, waxy build-up. Red, painfully inflamed ears. What do all these things have in common? All are symptoms of otitis externa, or what is commonly referred to as ear infections. If you have ever groaned inwardly and felt dismay the moment your dog starts shaking his head or rubbing his ears along the nearest available surface, you’re not alone. Unfortunately, too many dog owners are more than familiar with this recurring medical problem. Often, it is accompanied by an offensive odor and one can only imagine how overwhelming the smell is to the suffering pup!
Canine ear infections result from an overgrowth of yeast or bacteria in the ear canal, causing redness, irritation and a heavy accumulation of wax. Likely triggers of these maladies are skin reactions to inhaled allergens – like pollen, mold or dust mites – or food allergies and sensitivities. Be aware that both large ears and swimming predispose dogs to ear infections.
Humans tend to develop ear infections as a result of viral infections, typically in infancy or early youth. As youngsters, our Eustachian tubes are very small. Respiratory congestion can lead to blockage of these canals, resulting in otitis media (a middle ear infection). Because the infection is internal, they frequently require oral antibiotics. In contrast, pets usually develop ear infections as adults, and the infection is almost always localized in the external portion of the ear. In most cases, the application of prescription drops or ointments directly into the ear canal usually resolves the illness. If you suspect your dog may be suffering from an ear infection, please seek veterinarian assistance for diagnosis and treatment. If necessary, your vet may prescribe a topical medicine and advise routine cleaning.
