Biothane Check Cord
Made from 3/8 wide (flat) Biothane, this Herm Sprenger Stainless Steel INOX clip is designed for obedience, tracking and other activities, being both waterproof and odorless, while still having the luxe feel of leather.
This check cord is an excellent tool for young dogs that are learning obedience at a distance, or for older dogs that need a reminder. It allows the handler to give the dog a little more freedom, but still keeps the handler in control. Perfect for reinforcing recall, retrieve return, etc with a young dog.
We have found this style of check cord to be far and away the best option when it comes to check cords.
