If your dog's inner ears appear dirty, clean them with a cotton ball or
piece of gauze dampened with mineral oil, hydrogen peroxide or a liquid ear cleaner specially formulated for this purpose.
Once you've controlled the bleeding by applying pressure with «something clean and soft» (a
piece of gauze, tissues, or a towel will do),
dampen another
piece of clean material with cool water and wrap it around the detached part
of your ear, Dr. Lai - Becker said.
