Rolls (Pack of 5). Natural chewable collagen treat for dogs. Made from the collagen extracted from grass-fed cattle hide. The collagen proteins are hydrolysed and broken down through a heating process into smaller more easily digested molecules. The collagen is then shaped and baked where it acquires its bread like texture before being dripped into real Beef. Collagen chews help stimulate cartilage production, cushioning joints and therefore helps to reduce joint pain. They also help improve muscular strength and gut health. PLEASE NOTE: Brand name may vary.
