My little boy, a shitzu poodle mix, was diagnosed at 4 months with a liver shunt. He's on a vegetarian diet of boiled eggs, yogurt and kidney beans, fruits, vegetables and oils. It worked for him up until recently, but now he has lost muscle and fat and is a skeleton. He still runs around like crazy and has fun but his episodes are more frequent and I'm starting to feel we're losing the battle. Can you please advise on a new diet with exact measurements I can try that can help add some fat to his little body? I even started milk thistle yesterday, not sure if that'll help. Thank u so much!
