100% natural, our shed deer antlers make healthy and long-lasting chews. They are also low in fat, provide minerals and nutrients, such as calcium and phosphorus, and help to clean teeth. These are split right down the middle to expose all of the yummy marrow. Better for dogs new to antlers, puppies and smaller dogs give one a try. Remember though antler chewing should be supervised and take an antler away before it gets to be choking size.
