Slappies®! Shake, shake, shake! Dogs will love Slappies® because of the flapping that will happen when they shake the toy. When gripped by the squeaker TPR (Thermoplastic Rubber) ball in the head of the toy and shaken, the arms and legs flap around the pet’s head, appealing to the dog’s natural instincts. The stuff-less 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 with reinforced seam tape to make this toy more durable for “ruff” play.
