We've given that brand of dog bone to our pups, usually the smaller round ones. Our two are free to roam the house when we're gone and the bones are all around the living room (all picked clean
). If there are any that are really small I throw them out after they get all of the stuff off the outside because I don't want to take a chance on them choking. But so far we haven't had a problem with the larger ones. I don't even know if they chew on them when we're gone, I think they just sleep. lol The only thing I would watch for is chipping. I don't think they're supposed to splinter but on the small round ones there have been times when the wall part was fairly thin and the dogs were able to chip pieces off. If I get any like that in the pack I supervise them chewing it and then throw it away.
