Can you put a pattern to or link the trembling to other things happening concurrently? Or does he just spontaneously start trembling out of the blue? Yorkies are emotional, passionate dogs that can tremble or shake from excitement, fear, wanting something or anxiety but it can also be from pain. If the trembling just starts out of the blue and is pretty consistent, I believe I might want to go ahead and find out if there is a shunt present via the scintigraphy.

Unless the trembling is out-of-the blue and not brought on by anything you can recognize and/or your dog is not head-rubbing, lethargic, vomiting or spitting up bile or having other symptoms to indicate he's uncomfortable to miserable, he maybe does just have MVD that is responsive to the new diet. Maybe you could try another BAT to check what bile acid levels are now to try to see where he is.

Tibbe's BAT test done two years ago was $78.00. He then had an abdominal sonogram and a scintigraphy which ruled-out liver shunt, showed some small kidney stones in the sono but the vets decided he wasn't then a candidate for liver biopsy to give him a differential diagnosis of MVD with concurrent IBS and start him on a hepatic diet. His IBS won't allow a full hepatic diet yet so now we're at almost half hepatic and half Hill's I/D GI and he's doing very well at age 7 1/2.
