There is nothing your pet won’t do for a Venison Liver treat. It’s dry, light and crunchy, making it easy to break into small pieces and hide in your pocket. See how long it takes your cat or dog to come when you call it now... A little liver goes a long way, so we recommend using this treat as a reward only. * Liver is high in vitamin A, so should be used in moderation (i.e. less than the equivalent of two full meals a week).
