Kong Ballistic Tug Dog Toy KONG Ballistic is a line of tough, plush toys with a unique patented design that makes them more durable than other plush toys. Covered with a soft fleece material, Ballistic toys are cuddly and gentle on teeth and gums. Under the fleece are two additional layers of material, secured with eight rows of stitching for strength. Each toy squeaks, with squeakers enclosed in an individual nylon pouch to help prevent damage. Ballistic toys come in fun shapes, plus they float and are machine washable.
