Our one year old pit bull mix is an extreme chewer, and she is yet to destroy the Tux. I say "yet" because she has shredded almost EVERYTHING, including the West Paw Hurley; she even breaks off large pieces of nylabones. Though she has ripped off micro pieces of the Tux, 99% of it is still intact, leaving my husband and I are beyond impressed. My one suggestion is not to use this as a treat toy . . . meaning, do not put a bone inside of it (like the picture suggests), as there will be ZERO challenge for your dog. Keep it as a chew toy, one that occupies your dog's time and not one that your dog will walk away from once the treat is eaten. To get my dog to start chewing it, I will sometimes use peanut butter.
