Country Butcher knuckles consist of two knuckles, the femur and the saddle. These are both knuckles from a USA beef femur bone, dipped in natural liquid smoke and oven baked with no artificial ingredients. Meat on the knuckles is purposely left on for a better chewing experience. This all-natural chew is best for medium to large dogs. All Country Butcher products are 100% grown and made in the USA.
