You need to get a referral to an internal medicine vet or a vet school if you have one close enough. Most general practice vets don't see enough cases to have the experience and training to diagnose and treat liver shunts/disease.
How close are you to Ohio State? They have an excellent vet school.
You can waste a lot of time and money trying to get answers from a general practice vet. A specialist or vet school will repeat all the tests anyway.
I am very concerned that they did a biopsy. That is a very invasive test and should be done as a last resort. There are many less invasive and more accurate tests that should be done before a biopsy like a Protein C test, scintigraphy, etc.
Ultrasounds can be low as 60% reliable at detecting shunts, especially in small dogs. Is that how they ruled out a shunt? |
