Have you tried cleaning it with Hydrogen Peroxide? This will help "boil"away any germs and bacteria, carefully use a cotton swab to absorb any excess liquid and clean the ear as much as possible. Continue to do this until the "boiling" stops. Hope this will help. Janes
Purchase Zymox from Amazon. It costs less than $10 and does not require a prescription. It worked within days for my shihtzu.
