Peggy was diagnosed with a lemon size liver tumor on Dec. 8. She was given only 1 to 6 months to live. They expect her liver to fail! She is acting fine. They do not think that it has spread. Tell me liver surgery is very hard to recover from for dogs and will not give her any more time if it has spread at all. Have seen a holistic vet and have her on suppliments and new diet. Any experience with these liver tumors? Please help.
