Air Kong® Squeaker Footballs are made with the same high-quality, rugged synthetic felt material as standard tennis balls. They're non-toxic, easy-to-clean, brightly colored, squeak when squeezed, and they float. KONG AirDog® Squeaker Football combines two classic dog toys -the tennis ball and the squeaker - to create the perfect fetch toy. The non-abrasive, high-quality material will not wear down dogs’ teeth. Find your dog’s favorite AirDog® shape and let the games begin.
