This TPR ball toy is bouncy for thrilling games of fetch, but it also provides vital dental care in the form of little nubs that massage and clean around your dog's gums. Also, there are slots to fill with treats for a tasty surprise. The squeaky tennis ball inside can even be replaced if it gets mucky or punctured. Little jaws can easily pick up and play with the toy, making it a toy for all shapes and sizes of dogs.
