Some bones, especially chicken bones, also splinter and cause all kinds of serious havoc on the digestive system. I've had pork bones break in scary ways as well when the dogs got into them. I personally don't give my dogs anything but rawhides and large beef bones anymore, both of which you just have to buy specially really. On the subject of actual marrow, it adds a lot to soups and stews. Usually added via just cooking the bones in the soup/stew and removing towards the end.
