The bone portion is defined by an elongated shaft terminating at opposite ends. A first terminal end and a second terminal end of the shaft are defined by a pair of condyles, or in the alternative, by a rounded body. The elongated shaft is defined by a narrow middle portion and widening at a first terminal end and a second terminal end. The meat portion circumscribes a terminal end the bone portion. The meat portion further extends toward a middle portion of a shaft of the bone portion, wherein a sufficient quantity of the bone portion is available for use by a canine.
