Hi there, what is your vet recommending at this point as far as further diagnostics? My initial vet recommended biopsy after a free standing bile acids test came back at 82. I went to a specialist after researching the beans out of liver disease and he felt that ultrasound would be better at that time (less invasive/less risk).
Before I had the ultrasound done my boy was started on a daily dose of Denamarin (milk thistle and SamE combo). This is a neutraceutical that is liver supportive.
I've seen marked improvement on the Denamarin as well as a modified protein diet combined with Dr. Dodd's liver cleansing diet.
I would recommend these sites to check out:
this one is a forum on yahoo with excellent and plentiful info as well as people experienced with liver issues/disease.
As far as the ultrasound pricing goes...well, I know that it was expensive for me. But the most important thing is to find a very good sonographer preferably one adept at locating shunts and other maladies in the canine liver.
I hope this helps some, I will keep your sweet boy in my thoughts and prayers.
