Gina,
I am so sorry you are going thru this. You are wonderful for rescuing her.
Here are a couple of things right off the bat...
1. Redo a correct Bile Acid Test
2. NO LIVER - EVER!!! Organ Meats are extremely dangerous for liver compromised animals and should be avoided 100%
3. Egg in very small quantities is ok, but I would skip it for now.
4. Wellness puppy food is probably too high in protein for a liver compromised dog. Hill l/d wet is recommended and Royal Cain makes an Rx Dry food for liver issues. Also Natural Balance Veggie dry is ok too.
Here is a Yahoo Group that deals with Liver Issues. They can Help and Guide you further...
