BUILT FOR TOUGH CHEWERS With three solid lobes, Tux is our toughest treat toy - made to stand up to some fearsome fangs. Tux's treat-hiding hollow cavity makes it ideal for short-snouted breeds to get to the nut butters, biscuits, and meaty bits. Once treats are long gone, Tux floats, bounces, and hangs tough through serious chew sessions.
