“Dogs love the sound of an empty water bottle! Designed to provide a protective barrier around a water bottle, Crinkits give your dog an interactive toy they won’t want to put down. Our very durable material allows for tough chewers to play with an empty water bottle. Use the Crinkit as treat dispenser by putting a smaller 8oz or 12 oz water bottle inside the Crinkit, which allows room for a treat on the end where you in insert the bottle. Does your dog love water, because the Crinkit floats!! Although the Crinkit is very durable, no dog toy is indestructible. We always recommend supervising your dog when they are playing with their Crinkit. ” – from Zigoo Pets
