It bounces wild and crazy! Throw it and your dog won't know which way it will bounce this time. Ooooh, exciting! The Kong Jump'n Jack has more tooth cleaning surfaces than many other toys. The slits work to clean your dog's teeth and exercise the gums. Kong Jump'n Jack uses a natural rubber formula that is durable, flexible and of course, non-toxic. It is very tough.
