Amazon.comSqueaker toys and tennis balls: two canine favorites brought together at last. Tailor-made for games of chase and fetch this toy conceals an irresistible squeaker inside. The dumbbell shape has a silly unpredictable bounce and it even floats for hours of retrieving fun (and training) by land or by sea. The Air Kong squeaker dumbbell is made in the USA from durable high-quality tennis-ball material. Unlike typical tennis balls however the non-toxic felt covering on an Air Kong is specially designed not to wear down dogs teeth as they play. The large dumbbell measures 9-1/4 inches long and is ideal for larger breeds--or smaller ones who like to run with the big dogs. --Mary ParkProduct DescriptionKONG AirDog combines two classic dog toys -the tennis ball and the squeaker-to create the perfect fetch toy.
