I have been training my pup with a plain bumper, a Dokken, and bird wings with no big problems. But a little while back he found a wing at puppy level and devoured/made a mess with it. Now whenever I use a wing of any sort in training he runs around and chews on it, and won't fetch it like a dummy. I'm scared to use frozen birds until this is cleared up, how do I get him to stop eating the wings?
