KONG Rewards Tipsy is an action-packed and mentally stimulating food or treat dispenser for curious dogs who need an extra challenge and slower feeding. This wobbling toy sits upright, with a ball in the open upper half to slow down fast eaters and provide added challenges, while the lower half is weighted to encourage the wobbling action as dogs knock the toy around with their nose or paws. The ball can be removed for easier reward and encouragement, then replaced to increase the challenge. The KONG Rewards Tipsy is also ideal for weight loss, giving dogs exercise while they work to eat their food. The unpredictable movement stimulates natural foraging instincts, keeping even the most seasoned dogs challenged. Ideal for indoor enrichment. Top unscrews for easy cleaning.
