What a bad situation. I'm so sorry. I have a much milder case of it here with Rocky and Scout (heck everybody picks on Scout). Anyway, last year I tried Clomicalm and it was a compounded cream that I rubbed in Rocky's ear. I can't say that it helped, it just seemed to make Rocky a little spacey acting and when he'd come off of it it he acted worse in my opinion. That doesn't mean it wouldn't work for you. Maybe you could ask about a cream instead of a pill?

Good luck with the new vet. Fingers and paws crossed that they offer some help. (((HUGS))) for you!
