Give your dog a healthy way to burn off energy with the Outward Hound Hedgie Challenge Puzzle Dog Toy. A true boredom buster, this interactive, plush puzzle toy features a hedgehog body with three squeaky rings. Your dog will love to pull the rings off, which encourages mental stimulation, and then you can use them for a game of fetch when he’s done. Keep the fun going by putting the rings back on the hedgehog, and he’ll keep going back for more. The design features invincible squeakers that continue to squeak even if punctured.
