Enrich your pet's playtime with fun giggle sounds using JW's Hol-ee Giggler Dog Toy! Made with the same durable; natural rubber as the popular Hol-ee Roller; the Hol-ee Giggler adds extra fun with its unpredictable giggler inside the ball that "giggles" as your dog interacts and plays with the toy. The unique openings allow pet-parents to Hack Your Hol-ee by stuffing it with treats or other fun toys. JW's Hol-ee Giggler is designed to enrich playtime by stimulating auditory senses through new; fun sounds that go beyond the common squeak.PRODUCT NOTE: Supervise your dog during playtime; and remove the toy from your dog if it becomes damaged or parts become separated. No dog toy is indestructible; and every dog interacts with its toys differently. Supervised play will go a long way to helping your dog's toys last longer and keeping your pet safe.
