The toughest treat toy, Tux is made to stand up to some fearsome fangs. Nut butters, biscuits, and meaty bits all get gnawed free whenever a dog is near. Create a Tux-cicle to keep dogs cool in hot months. Simply fill with broth, gravy, or wet food and freeze. Tux is also fun to toss, fetch, and chew even after the treats are gone.
