Why Are Dogs So Crazy About Bones?

This is a really great read. I learned a lot from it. Thanks for sharing this! I can attest to this. Our labrador retriever, Bruce, loves chewing bones especially the really big ones. He also won't let it go even if it's already so old. It just scares me sometimes because he sometimes manages to break the bone into really tiny pieces. I don't want those pieces to get stuck on his throat or something like that. To avoid that, I just buy those artificial bones from pet stores. I think it's called Dentastix or something like that.
