Jones Natural Chews 4 inch Center Bone is cut from USA- raised, natural beef tibia or femur. It is oven-baked to smoky perfection with a rich and full flavor with no artificial ingredients added. A perennial best-seller, this is cut to an appropriate length for small or medium sized dogs. Extra meaty tidbits are left on the bone and marrow is often found inside, making this a great chance to add protein to your dog's diet. The gnawing action from chewing helps keep dogs teeth and gums free from plaque buildup. This single ingredient, natural dog chew provides hours of chewing entertainment. All Jones Natural Chews products are raised and handcrafted in the USA and responsibly sourced.
