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 can't 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.
