Tumble, bounce, solve and play! Simply toss the Puzzle Jack for engaged, interactive play, or hand it off for challenge-based independent chew sessions. This toy is made with durable, thick walls that encourage healthy chewing for the most serious chewers to the gentlest. Unscrew the cap for easy loading and cleaning, and insert the kibble or treats. Dogs delight in playing and seeing the food dispense through the Puzzle Jack’s other holes. Due to its unique size and shape, the toy bounces erratically and can make a game of fetch much more interesting. Made with Chew Pro™, GURU’s ultra-durable, custom, non-toxic thermoplastic rubber formulated specifically for tough chew sessions. This toy is also top-shelf dishwasher safe for easy clean up.
