American Made Resco Cordo-Hyde Snap Leads. Our cordo-hyde lead with a bolt snap on one end. Cordo-hyde is a unique wax-coated cotton material that can be balled up in the hand to hide the lead and it"s stiff enough so that the dog will respond to a handler"s tug on the lead in the show ring. You will have quick release with our American made nickel plated bolt snap.
