Whether your dog has been naughty or nice this year, KONG AirDog Squeaker toys will make this a holiday season to remember! These toys are designed to be tougher and safer than standard tennis balls.

Unlike regular (boring) tennis balls, KONG AirDog toys squeak and are available in interesting shapes. Game, set, match! They feature durable rubber walls designed to withstand rowdy games of fetch. Just give one a toss and watch your dog have a holly jolly good time.
