I agree with the previous posters -- If you can get Pixie to UT for surgery (if she in fact needs surgery) then that is where you should go. If it is MVD, a trip to cornell might be the way to go.
My dog with MVD has had very high bile acids depending on her diet, even higher than Pixie's pre reading.
You have to know what you are dealing with exactly before getting upset. Lots of MVD and LS babies do very well on the proper diet after surgery.
I'm sorry you have to go through this and we send Pixie yorkie hugs.
