It is as tough as reputed to be! Not a mark from the shark teeth on either of them (I got a pink one and a green one, both large) despite the girls play tug together with them and chewing on them. That said my dogs prefer plushies to hard plastic toys, so these weren't quite as big a hit as I was hoping. Still pretty awesome though, especially if you've got a dog who is hard on toys and likes to fetch and tug!
