Dogs love tennis balls because they are easy to throw (by humans) and retrieve (by dogs). With the KONG® AirDog® Squeaker Dumbbell, the tennis ball as a dog toy has been expanded even further and additionally equipped with a squeaker. The dumbbell-shaped toy in tennis ball look can be thrown just as well as a tennis ball. However, the KONG® AirDog® Squeaker Dumbbell bounces unpredictably after impact, making it even more exciting than a tennis ball, because bouncing is a real challenge for the dog. But once he has found the toy, the bone shape makes it easy for him to pick up and carry. The built-in squeaker encourages the dog to chew and play with the toy a lot. So it offers a lot of entertainment and play fun. The surface of the KONG® AirDog® Squeaker Dumbbell looks just like a tennis ball, but it is made of a special material that is gentler on teeth and gums than the felt surface of a real tennis ball. Note: Please never leave the pet unattended while playing. No toy is indestructible. To prevent injuries, the toy should be checked regularly for damage or loose parts and replaced if necessary.
