Genie, you & your family are in my prayers, We had to go through this about 2 years ago with my boy yorkie Tucker, he had a liver shunt..Hang in there girl...sounds like you are on top of it..Send Cookie a big Hug & kiss for me...I will be praying for him everyday, its a hard road with liver problems, but alot of yorkies do great on diet and meds..and I know he will too....

Please let us know how he is doing...
