You know, I've never even thought to try! I'm sure if I did, Double-Oh would LOVE it, but the dogs would try stealing it.. The last time I got them one I put them on the back porch (for obvious reasons) and the bone DISAPPEARED. It did not fall off the deck, it just vanished! And there was no way they could have eaten it, either. I don't know, its a mystery to me!

But you can check with your local grocery store in the meat department, ask a butcher about knuckle bones or "stew bones". You DO NOT want them cooked! If they are cooked, or smoked, they can splinter and cause lots of problems!
