AIRDOG Yellow Squeaker Dumbbell combines two canine favourites - tennis ball and squeaker. This toy hides an irresistible squeaker inside. The dumbbell shape has a silly, unpredictable bounce and it even floats for hours of retrieving fun (and training) on land or in the water. The Air KONG squeaker dumbbell is made from durable, high-quality tennis-ball material. Unlike tennis balls, the non-toxic felt covering on an Air Kong is specially designed not to wear down dogs' teeth as they play.
