The BullySafe offers peace of mind by promoting proper chewing, making each treat last longer for more enjoyment (and bully stick savings!). Its crafted from tough, non-toxic nylon to withstand even the most serious chewers, so pups can enjoy their chews without the risk of choking or swallowing big pieces. The easy-to-use, adjustable design fits chews of all sizes, and its a perfect fit with grass-fed, free-range Woof Bully Sticks.
