Contain ridges to improve dental health and reduce plaque buildup. Just two ingredients! The chews are hand-wrapped and made from 100% digestible, human-grade collagen sourced from cattle that are born and raised in the USA. Collagen is naturally high in protein, low in fat, and packed with nutritional benefits and flavor. The wild caught Atlantic cod skins are sustainably sourced and naturally rich in protein and omega-3 fatty acids to help support healthy skin and coat and provide major chewing satisfaction.
