Is your dog slipping out of his collar when you go for a walk? Try a no-slip, adjustable martingale collar from Country Brook Design! This martingale collar is crafted from heavy duty polyester webbing and it features a premium side release buckle, which provides easy access for quick release and adjustability. These collars are designed to prevent your dog from slipping out of its collar while being walked on a leash and can also be used as a training collar. The martingale collar is often referred to as a humane choke collar because the limited closure of the martingale prevents it from becoming too tight around your dog's neck. The collar features a twin loop design that works by tightening around his neck whenever he tugs away from you. Then the martingale will loosen back to its original state whenever he stops struggling against it. For the strongest of dogs and the excited-jumpy puppies, a martingale collar is the perfect way to insure safety and security during your daily walks. ____Directions For Use: By adjusting the metal slide, open the collar loop wide. Slip it over your dog's neck and decrease size until you can comfortably slip only a couple of fingers under the collar. The unique limited closure prevents the choke from becoming too tight.
