Since reading the thread on rawhides, I am so afraid to give my guys them anymore for fear of choking. If you do, just make sure you are with them and watch them closely. I don't think there's too much there calorie wise. I started giving them "velvet bones." Most stores have them. They come in flavors with different colorings and are made of a corn starch base. Very safe and they love them. But VERY expensive. The x-large ones are 10.00 and they finish them in a hour or so! I'm still on the never ending search for a "chew" that is safe, good for them, not to expensive, and one they won't devour in 10 minutes!
