Our GOOD BUDDY Meaty Center Bone is a high quality beef femur bone dipped in natural liquid smoke and baked. Its natural meaty center provides hours of chewing enjoyment! The bones are carefully prepared to ensure they are both safe and tasty. They are dipped in natural liquid smoke and are then baked. Strict guidelines apply to the cooking process to ensure a moist, quality bone that reduces the chance of splintering. The liquid smoke is naturally processed by burning wood inside barrels and condensing the smoke into liquid. The liquid is then packaged and sent out as natural liquid smoke for our bones. We use this method because traditional smoking methods (burning wood chips and sending the smoke into the ovens) does not penetrate the bone. The natural liquid smoke penetrates the bone with extra flavor, is an antioxidant, and fights off bacteria.
