Ear infections are common in dogs and can be painful if left untreated. Some signs that your dog may have an ear infection include excessive scratching or rubbing of the ears, redness or swelling of the ear canal, a strong odor coming from the ear, discharge or pus in the ear, shaking or tilting of the head, and sensitivity or pain when the ears are touched. If you notice any of these symptoms, it's important to take your dog to the veterinarian for a proper diagnosis and treatment.
