i am sorry to hear about your pup. I don’t think you have enough information as this point. Generally speaking liver diets are reduced protein, but Beddlingtons are prone to copper storage issues, and often a reduction of copper helps. “In many cases, elevation of liver enzymes alone does not warrant a dietary change. In some instances, if the liver enzymes are consistently elevated, the pet may benefit from supplemental antioxidants. Liver cells may be partially protected from further damage when additional antioxidant precursors or antioxidants beyond those found in the diet are given. Some veterinary nutritionists and veterinarians recommend supplementation with Vitamin E, Vitamin C, Sadenosyl-
methionine (SAMe) and/or silymarin (Milk Thistle), but it is important to note that the
exact mechanism of action, dosing and efficacy of these supplements are still under
investigation.” http://www.vetmed.ucdavis.edu/vmth/small_animal/nutrition/client_info_sheets/encephalopathy.cfm
This is really a conversation with your vet, based on the diagnosis.
