Outward Hound Activity Matz are fun to use, easy to clean, and perfect for both mental and physical exercise. The Fast Food Fun activity mat comes with optional closures to level up the challenge! Once your dog has sniffed out the treats or kibble from the plush material, increase the challenge by placing food in the pockets and hiding them under an extra layer by stuffing in the hot dog. For an even harder challenge, hide the tasty rewards under hook & loop closures. When not in use, the activity mat folds up for easy storage.
