I am so sorry you are going thru this. I am in a similar situation with Tiki, my 7 month old Yorkie. Had pre-spay bloodwork that showed elevated bile acids, then had bile acid test and her post number is 47. They canceled her spay and we are now trying to decide the next steps in diagnosis.
I have gotten a big education and lots of help here on Yorkie Talk from members who have much experience with liver disease, and diagnosis, treatment, diet and important supplements. Check out my thread
http://www.yorkietalk.com/forums/yor...disease-6.html, and you will get some very good advice.
Seems like I hear of another young one having liver issues practically every day. You have come to the right place to learn how you can help Cricket. Good luck!
