How often you’re washing your dog’s ears depends on the dog’s ears and if they are prone to infections. Some dogs with ears that stick up and are open to the air may not need them cleaned more than a few times a year (unless they swim). Other dogs with floppy ears that stay moist inside may need them cleaned up to every other day to prevent infection. Ask your veterinarian what’s right for your particular dog. A good rule of thumb for floppy-eared dogs is once a week to be safe and to maintain clean ears for dogs. —Dr. Katy Nelson, DVM
