I am sorry that your baby is going through this but I would not give prednisone, that is just my opinion.
My dog Daisy was in full blown liver failure and the vets stopped all medication and put her on a liver cleanse diet and milk thistle.
Daisy situation might be alot different but her liver enzymes were severly elevated and she was so sick her stomach was black and that was due to her liver.
Daisy had lyme disease and then a severe reaction to her medication. You can read my thread on all that we went through.
I am happy to say that Daisy is doing well and her enzymes are normal, but I home cooked for 3 mon. She was on probiotics, and Sam-e.
