While you are at the vet's you may want to ask him for a recommendation of ear cleaning solution, and how to use it. I use it every time I give a bath to keep the ears clean and smelling great. The ear canal is L shaped and will build up wax if not cleaned. It's difficult to bathe and not get some water in the ear, putting the solution in will dry the ear and help keep the ph balance correct. If you do have ear mites (very likely) Mita-Clear is the most effective and best smelling product I have found.
