The Kong Wobbler Food Dispensing Dog Toy sits upright until pushed with a dog’s paw or nose, then wobbles, spins and rolls, dispensing treats through a hole near the top. The unpredictable movement keeps the toy challenging, even for seasoned Wobbler users. Use the Wobbler as an alternative to a dog bowl, and help to extend meal time and exercise your dog. The Wobbler is Made in the USA of durable, FDA food-approved, high-strength polymer. It unscrews for quick filling and easy clean-up, and is top-drawer dishwasher safe.
