Beef Knuckle Bone for all those knuckle heads that need something to chew! These animals are grass-fed in the USA. Grown here and manufactured by us gives us the ability to control the quality. No chemicals or smoke flavorings are used on any of our bones so you are sure to get the best quality out of the bone in a cooked form. Knuckles are great as a dental aid because it is softer on the teeth and the bones almost sand down. This is typical for joint bones like these knuckles, saddles and knee caps.
