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. Meet Tux, our toughest treat toy. Its shallow cavity makes it ideal for short-snouted breeds to get to the good stuff inside. Fill with dry treat or freeze with wet ones for long lasting mental enrichment.
