A simple way to clean your dog’s ears is with q-tips and hydrogen peroxide. The hydrogen peroxide is a safe cleaner that can loosen any deposits of wax and dirt without any discomfort to your pet. Dip one end of the q-tip in the hydrogen peroxide and swab only the outer canal of the ear. Never put the q-tip in the ear canal. Use the other end of the q-tip to dry and clean anything else out of the ear, and then use a second q-tip for the other ear in the same manner.
