These delicious duvoplus chew! snacks make dogs and their owners happy. The snacks are made of chicken and a collagen layer of rawhide packed with protein and no added sugar. The collagen layer is the deepest layer of rawhide and is closest to the muscles and organs. Compared to traditional rawhide snacks, these softer collagen snacks are more elastic and digestible. In addition, the dog snacks support healthy skin and coat, joints and dental health. A delicious treat and ideal pastime for dogs. But don't snack too much! Snacks serve to supplement and vary your dog's daily menu.
