Ear infections are surprisingly common in dogs, especially dogs with non-erect or particularly hairy ears. Have you noticed your dog shaking his head, scratching his ears, or walking in circles? These odd behaviors could be explained by an ear infection. Some other symptoms include: Brown, yellow, or bloody discharge, smelly ears, redness, swelling, or crustiness, hair loss around the ear, or eventually hearing loss. Hopefully you’ve noticed some other symptoms before it’s gotten to that point. It is important to take a dog with any of these symptoms to NOVA Pets. The doctor will examine your dog’s inner ears, and possibly take a sample if he thinks there might be a bacterial or yeast infection, or a parasite. Seriously waxy ears might call for an ear flush, but Dr. Masood does that all the time, so there’s nothing to worry about. All in all, it’s a quick exam and it will have your pup feeling and hearing better in no time!
