KONG Tugger Knots are tough, interactive tug and shake toys that dogs love. Each toy has knotted ropes inside for a realistic feel, which extend outside the toy creating tug handles at both ends. The ropes are looped together to absorb tugging stress and covered by a durable, double ply plush body. This unique design creates a captivating variety of textures and resistance and a squeaker inside adds to the fun.
