It's nearly impossible to find chew toys that my English Mastiff can't destroy in 30 minutes or less. So far, the TUX has not only held up to his chewing, but he loves it! We've stuffed it with all sorts of goodies and he keeps bringing it to me to refill. Our little dachshund/yorkie mix keeps trying to take it away- looks like we need to buy another one!
Great job on this product, thanks from the owner of a really big chewer!
