Keep your pup healthy and entertained our extra durable 6" water buffalo collagen rolls. Our rolls deliver a rich chewing experience and contain naturally occurring glucosamine, chondroitin and omega-3 fatty acids to help support joint, skin, coat and digestive health. Collagen is found below the top two layers of skin. These goodies are digestible, long lasting and the perfect alternative to rawhide. Each measures 6 in., but as with all natural chews, sizes will vary.
