Here is some information regarding ultrasound and the liver and here is the website it came from http://canineliverdiseasefoundation.org:
I would have a complete abdominal ultrasound done and not just the liver as it will show all the organs. Missy is on Ursodiol for her gallbladder problem.
Thanks, Jennifer! I'll check into it. I'm guessing I would have to go to UT for the ultrasound– if my vet had the capability, she probably would have done it. His bile duct test was normal. I believe that was a blood test. But maybe the bile acids test is different. I'm usually pretty good at knowing exactly what Spencer had done and the results, but those were a frantic few days and we were doing so many tests so quickly. I'm going to go back and re-read all the paperwork. I remember discussing a bile duct blockage as the root of his problem and ruling it out.
I'm glad Missy is still doing well! It's wonderful when these older Fanconi dogs keep beating the odds.
