What’s wrong with the black scabs on the tips of Teddy’s ears?

The black scabs on the tips of Teddy’s ears are usually caused by mites or fleas. If you find such symptoms, you should treat your dog promptly, otherwise the mites or fleas will spread to other parts of your dog’s body and cause serious discomfort to your dog. Teddy’s ears are crusty, whether caused by mites or fleas, and should be isolated from others or other animals, then the dog owner wears gloves, disinfects Teddy’s supplies and cleans the room. After doing the cleaning work, the dog owner uses a shaving tool and gently shaves the hair off the tips of Teddy’s ears, then uses hydrogen peroxide on the scabs, waits for the hydrogen peroxide to dry, then sprays the scabs with a skin inhibitor to inhibit bacteria, then puts an Elizabethan collar on Teddy and cuts Teddy’s nails short to keep him from licking and scratching the scabs.
