Wonder Bar Beef Liver Large is a large, long-lasting collagen dog chew made from beef gelatine and collagen, with a beef liver flavour and firm texture that gradually softens as your dog chews. With 74% protein and 0% fat, it provides a satisfying chew for dogs who enjoy firmer, longer-lasting treats.
Made with a simple, limited-ingredient recipe, Wonder Bar encourages natural chewing and is designed to be digestible without splintering like some harder chews. If your dog finds it too firm, one end can be soaked briefly in warm water before feeding.

Always supervise your dog while chewing and remove the chew if it becomes small enough to swallow or presents a choking risk.
