I agree with Jer Lin. I've not been in your situation, but you already seem to know how your Yorkie is reacting to everything better than your vet would know. I'd also suggest getting a second and maybe even third opinion from two other vets. Try and find a younger vet out of college. May sound stupid right? They actually have been the ones studying the newer technology and the newer study findings. They might have a better perspective for you. Good luck and let us know what you find out!
