Here's my post about my dog, Rudy's high liver enzymes, still pending...
http://www.pets.ca/forum/showthread.php?t=48334
He has seen the vet once since then, the levels are still high so she kept him on Denosyl and added Marin. I am giving him Milk Thistle caps every other day, despite the vet telling me to be cautious with herbs....She wants to do an ultrasound next time if they are still high.
Rudy just turned 12 so he is much older than your pup.
After the next visit, I will post if I have more information.
Good luck with your pup.
