My Scottie loves it! Also, it is almost the only chew toy he has kept for longer than a few minutes. The other ones that have passed the first few minutes test really aren't played with much. This bone is chewed on, tossed, chewed on, bounced on the ground and caught on the rebound, chewed on, brought for play with a human, chewed on, carried all over, chewed on, slept with as a pillow, and, did I mention that he CHEWS ON IT? He has had it for two months and it doesn't have a mark on it.
He has both sizes, but definitely prefers the smaller one.
