Planet Dog maintain that their customers tell them that dogs just don't want to put this toy down.  Some of them even call it a 'doggy dummy'!  Please be aware that the extra small size is for extra small dogs only.

Planet Dog have their own Chew-o-Meter based on the mechanics of a dog's jaw, the physics of size and shape and your dog's own chewing habits to help you chose exactly the right toy for your dog.  This one scores 3 chompers, making it perfect for average chewers.
