It sounds like you're dealing with an ear infection. The common signs include itching at the ears, shaking the head and inflammation/ debris visualized in the ear canal.

These can be treated with topical ear medication. The meds include an anti-fungal for the yeast, antibiotic for the bacteria and steroid for the inflammation in the ear canal. Otomax is the most commonly used. You may want to use a new vet if the one you have seen is not treating it appropriately.

In the mean time, you can clean out the ears with a diluted hydrogen peroxide solution or over the counter ear cleansing solution.

You can also give Benadryl (Diphenhydramine) at a dose of 1-2 mg per lb every 6-8 hours as needed for the itching.

I hope this helps, let me know if you have any other questions.
