The simple elegance of these braided leads adds strength, durability and confidence during your training sessions and walks with your dog. We use only heavy-duty, solid brass swivel clips and American steer hide. We find this leather to be the thickest, strongest lead material. Unless your dog chews on these leads (not allowed!), they will not crack or fray. We prefer a 6' lead for general use, and a 4' or a 21" lead for in-house use and close training.
