Check the inside of thdental-care-for-bichonse ear for accumulated wax and dirt. Begin by removing the long hair that leads to the ear canal. Use tweezers or a hemostat to pull out the excess hair. If this area is blocked, serious ear problems can occur. After removing the hair, dampen a Q-Tip with alcohol and carefully clean out the canal. Apply a bacterium inhibiting powder made for the purpose and available at most pet supply stores.
