Kong Air combines two classic dog toys, the tennis ball and the squeaker toy and puts them together in an instantly recognizable shape to create the perfect fetch toy. Special nonabrasive tennis ball fabric will not wear down a dog's teeth making it kind to your dog's teeth and gums. All squeaker units are recessed in rubber and covered with tennis ball fabric for safety. It also floats, so you could even take it along for a game at the beach. Give them a squeak! Medium: Approx 15.9 x 4.4 x 7.6 cm
