SHAKE AND LAUGH Dog Toys Ball, Interactive Dog Ball, No Paint, Gibbering Sound with Surface Concave Lines, L, 3.94 in (10 cm)

The sounding principle lies in the internal whistle propelling tube, which makes a sound when shaken, no batteries required. There are also several clutch pockets on the surface of the ball, making it easy for dogs of all sizes to pick up. Cleaning:  It is recommended to rinse the ball with water and clean the surface.  It is best not to immerse the ball in water, as it will cause water to accumulate in the sound pipe. Allow the ball to dry completely before giving it to your dog to play with. NOTE:  This toy is designed for pet interaction, not a chew toy.  It cant withstand long time gnawing by your dog.  Please make sure to keep it away from children to avoid accidents. This is a consumable item. If you find the toy is damaged, please buy a new model or multiple packs.
