Dogs love Slappies because of the slapping action that will happen when the dog shakes the toy. Perfect for dogs with strong prey drive! The stuffless tummy enhances the flapping action and makes the toy more durable for chewers. Each Slappies is designed with a reusable spiky TPR squeaker ball in the head and a squeaker in the tummy. Using POWER PLUSH construction means that each toy features a mesh lining, combined with reinforced seam tape to make this toy more durable for “ruff” play!
