Beef Knuckle. The knuckle is an exceptionally lean, very affordable cut from the Round (between the Top Round & Bottom Round). It's a great source of lean beef. Made with single ingredient, your pet is sure to come running to you with the opening of the bag! 
 
Dehydrated to extreme crisp, hear how the cow chips crackle with every bite they take! 
 
Did we say it smells good too?
