The Snuffle N' Treat Ball puzzle toy for dogs is a fun new way for your pet to get both physical and mental stimulation. It comes with six plush chipmunks that are used to cover the treat compartments in order to hide the tasty rewards. You can increase the challenge by stuffing them all the way in or make it easier for beginners by only putting the toys in halfway. Perfect for nose work/scent games, this treat dispenser dog puzzle will keep your dog busy for a long while. Run out of chipmunks? Replacement 3-packs are available to keep the fun going!
