KONG Holiday AirDog Donut combines two favorites— a tennis ball and a squeaker—into one fabulous fetch toy to help pups ring in the holidays with tons of fetching fun. KONG Tennis non-abrasive material is softer on teeth than regular tennis ball felt. The squeaker calls dogs to play while the dynamic bounce makes for unpredictable bouncing, rolling, fetching fun with a dog-friendly holiday wreath with a hole for easy grabbing.
