These leashes are different than any other dog leash because they come with a collar, these leads are often called collar and leash combos.
When a dog pulls on lead the martingale can only tighten so far. They are quick and easy to put on and take off.
The Martingale collar is made with high strength nylon webbing then covered with a double layer of fleece that will rest on the dog’s neck along with colorful ribbon on top. The limited slip part of the collar is braided half the thickness of the leash to provide a smooth release and increase in tension.
They are 5 feet long from tip of collar to tip of handle.
