The KONG AirDog Spinner combines two classic dog toys — the tennis ball and the squeaker toy — to create the perfect fetch toy. Our durable, high-quality AirDog Spinner will not wear down a dog’s teeth. It’s made with a special nonabrasive felt, compared to the abrasive material on normal tennis balls. Throw the AirDog Spinner, and watch it roll and bounce unpredictably for great games of chase and fetch.
