I have a young bc/cattle dog. When I get him a new toy, it usually takes awhile for him to develop interest in it. And he's the kind of dog that really only wants to play with me, not by himself. From the moment I pulled this out of the box, he loved. He immediately started chewing on it. He carries it around and shakes it and tries to get other dogs to play tug. I got it with the intention of stuffing it with treats for when we are at agility trials. However, so far, he loves it plain. It has a squeaker in the head. The rubber is softer than I expected which makes it "shakable". So far he has not damaged it even after a few chew sessions. However, I would call him a moderate chewer. I will be buying more in case they quit carrying this.
