I was following the other thread you posted about your dog having the drooling problem.
http://www.yorkietalk.com/forums/sic...ml#post3743822 I would not stop going forward w the testing. W the neuro symptoms and the abnormal blood tests, plus the improvement on the diet, I would suspect the vet is right that something is going on here. I hope they can get to the bottom of what is going on w your little one. Please keep in touch and let us know how you are making out.
