IrRAWsistible’s recreational bones are the beef femur (filled with marrow) and hip bones (knuckles). They should be gnawed on only and not consumed, with the exception of any remaining beef meat on the bone as well as the marrow.  These bones provide mental stimulation and oral health benefits. When your dog chews on a raw recreational bone, it helps to break down tartar and reduces the risk of gum disease, effectively scaling the teeth. Never serve cooked bones as they are prone to splintering.  Always supervise your pet when feeding raw bones.
