After cleaning, you need to use ear mite medicine for treatment. Generally, recovery will take about 7-14 days. Pet owners also need to be careful to keep their distance from their puppies and wash their hands with hand sanitizer after each contact with them to avoid introducing germs to other dogs.

What to do if there are ear mites in the dog’s ears

Since ear mites can cause a large amount of dirt to be produced in the dog's ears, owners need to use a pet-specific ear cleaning solution to clean the dog's ears first. Generally, drop the ear cleaning liquid into the dog's ear, then rub it gently for a few minutes, loosen the dog's head and let the dog shake out the dirt. The owner can then use a cotton swab to wipe the outer auricle clean.
