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.
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.
