Customer Question

My dog was fine then out of the blue he started shaking his head and scratching his ear. Almost like there is something in there. But he doesn't sit still long enough for me to look.

Hello, Very sorry to hear about Ziggy.What you are describing sounds consistent with otitis externa (an ear infection). This is usually caused by a bacterial and/or yeast infection. Ear mites tend to be more common in puppies/kittens or pets that remain outdoors., the following would be done at your veterinarian,Examination of the ear canal. prescription for a ear medication and ear flush is sent homeIf there is substantial inflammation/swelling, a steroid injection or oral medication is prescribedIf there is substantial bacteria identified on the cytology, an oral antibiotic should be prescribed, suppose there is no ear infection?Well, sometimes, an allergic reaction can cause an acute onset of these symptoms. To help out briefly, you can give some over the counter benadryl antihistamine, but he'll need to get in to a vet to have the ear canals checked.Benadryl can be given at a dose of 1mg per pound of body weight. Keep in mind, Benadryl tablets and liquids come in different sizes. So, an approximately 25 pound dog can get a full 25mg tablet or a half of a 50mg tablet. I usually avoid the liquid Benadryl in larger dogs (you would have to give too much of it). You can give Benadryl every 8-12 hours. Good Luck!Dr. Andy
