How to clean your dog's ears
Inspect the general condition of your dog's ears.
Have your dog sit or stand near you so you can see easily in its ears. If all you see is dirt or normal earwax you can begin cleaning your dog's ears.

Possible answers: -- Examine the inner layers of the ear, from the inside out. If the ear canals do not open, your dog is likely suffering from a twitching and bumpy ear canal. -- If the ear wax is matted, you can try to remove it. Untape your dog's whiskers at one side of the ear and then gently take off the top layer and shake the ear down so dirt and any excess earwax is removed. -- Look for any drainage of fluid from the ear (clear or gray/brown), thick waxy material, or any scratches, scabs or wounds. If you see any of these signs do not clean the ear and contact your dog's veterinarian for advice. -- Your dog will be able to easily detect wear and tear caused by rodent bites due to the outer coating of their ears and teeth. If your dog's ears feel dirty, wear soft cloth or underwear during the cleaning process.
