Kong Snuzzles Bunny Size:Small It is not a chemicalKONG Snuzzles Bunny is plump full of fun with a full body squeaker that calls out with a long, loud squeak. The uber plush exterior continues the delight while satisfying instinctual chewing behavior and crackly ears extend the engagement. The dense mouthfeel continues the engagement by rewarding appropriate play with every bite. Ideal for indoor fun, the flat shape is sure to engage with dogs of all different sizes.
