Fresh Chews Baby are made from real animal hide; these chews are suitable for puppies aged 2 to 12 months. Made from real beef hide, they help reduce the formation of tartar, partly due to their abrasive effect, but also thanks to the sodium hexametaphosphate in the formula, which helps stop the formation of tartar by binding the calcium found in saliva. They also contain calcium, which puppies need to build strong bones and teeth as they are growing.
