The dog is shaking its ears with its head on the side, at which point the owner is advised to check the dog’s ears for brown discharge or redness. It is highly likely that the dog is frequently shaking its ears because it has been infected with ear mites, causing foreign bodies and itching in the ears and causing discomfort in the dog. Owners need to purchase ear drops to clean their dog’s ears 1-2 times a day for more than a week, and if necessary, apply anti-inflammatory medication to the ears. Ear mites are ectoparasitic diseases that cause inflammation of the outer ear due to the external ear canal. The main symptoms are hair loss, inflammation, odor, reddish-brown scabs and ear wax visible in the ear canal, and the dog will appear to scratch the ear and shake its head. Secondary to bacterial infection, otitis, inner ear infection and meningitis can occur, among others.
