Outward Hound's Activity Matz are great for both mental and physical exercise. They're made with a plush material that encourages sniffing around, as well as optional closure systems to make the challenge more interesting! When your dog has found all of their treats or kibble inside the plush french fries, increase the difficulty by placing food into hidden pockets and stuffing the hot dog so they'll have an even harder time finding them - extending playtime! When not in use, the Activity Matz can be folded up for easy storage.
