PetSafe Large Martingale Collar with Quick Snap Buckle, 1", Apple Green;

The PetSafe(R) Martingale Collar is "Your Dog's Neck's Best Friend". With a leash or with your hand, the PetSafe collar tightens to give greater control and reduces the risk of escape. Because it offers limited closure, it's safer than a traditional choke collar . Unlike other collars, the measurement taken for the PetSafe Collar is at the top if the neck directly behind the ears. This corresponds with the size of the collar in the closed position, so it is not necessary to add Inch. For example if your adult dog measures 14-inch directly behind the ears, choose a medium collar. Sizing recommendations 5-inch - 8-inch Petite, 8-inch - 12-inch Small, 10-inch - 16-inch Medium, 14-inch - 20-inch Large, 18-inch - 28-inch Extra Large. Once you've selected the proper size, simply place the larger opening over your dog's head. Adjust to fit by pushing the nylon through the slide. When tightened with a leash or by grasping the smaller nylon loop like a handle, the two metal rings should touch directly behind your dog's ears. Attach tags to these rings rather than the D-ring. The smaller nylon loop will lie flat after few days of wear.
