Paws & Co. wrapped elk antler chews are ideal for heavy chewers and high-energy pups. The premium-grade antlers are naturally shed from wild elk, which means no elk are harmed while providing these eco-friendly dog chews. The antlers are wrapped with a U.S.-sourced bully stick, creating an extra challenge and reward and making the antler chews even longer-lasting. The antler chews offer no mess, no artificial additives and no fillers.
