KONG Wild Knots Bear Dog Toy Soft on the outside and strong on the inside: this is how this KONG bear toy is defined, which will become your dog's favourite. The interior of the toy is made up of a rope skeleton with knots that give it strength and great fun. KONG Wild Knots toys have a small whistle built into the gut, which is used to attract the dog's attention. Also, the bear has very little filler material, so it won't make a big mess around the house even if the outside has been torn open after some wild play.
