Our toughest eco-friendly treat toy, Tux has stood the test of time and up to some fearsome fangs. Nut butters, biscuits, and meaty bits all get gnawed free whenever a dog is near. Creating a Tux-cicle is a great way 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.
