The Ultimate Leash Designer Series Martingale Dog Collar | Made in The USA | Adjustable, Premium, Heavy Duty, Durable, Strong Training Collar | Nickel Plated Steel WHY USE A MARTINGALE COLLAR  Martingale collars are great for taking your dog on a walk or for training. They are designed to gently tighten if your pet pulls on the leash or tries to pull out of the collar. Martingale collars hang comfortably around your dogs neck when they are off leash or when no pressure is on the leash. Martingale collars tighten when pressure is applied & loosen when pressure is released. A Martingale collar is the most humane collar for your best friend. POWER STEERING FOR YOUR DOG - The Martingale Collar is a favorite among dog owners that require a little extra control of their dog. It is a cross between a standard collar and a choke chain collar. The Martingale Collar Designer Series is constructed from heavy duty 1 cotton webbing. The chain and buckle are heavy duty nickel plated steel. Martingale collars are available in 3 adjustable sizes ranging from 16-36". THE PERFECT COLLAR FOR ALL DOGS  No matter how big or small, a Martingale Collar will work for you & your dog. Originally designed for sight hound breeds, Martingale collars are now more widely used for all size breeds. For larger dogs, a martingale collar will offer more control. For dogs that are leash training, a Martingale collar is an excellent training tool, helping them to learn not to pull. The Ultimate Leash Martingale collars provide control and prevent the chance of escape. QUALITY WE STAND BEHIND  Our products are handcrafted in the USA.
