The Kong Air Squeaker Dumbbell Dog Toy is unique in that it combines two favorite dog toys in one. This canine favorite is more than just a squeaker toy because it also features tennis balls on each end. However, unlike tennis balls, the non-toxic felt covering will never wear down your dog's teeth. Because of the shape, the toy has an unpredictable bounce that will keep your dog guessing for hours. Fetch will be more fun than ever with this squeaky little wonder.
