NWT Max & Neo BLACK Nylon Buckle Martingdale Dog Collar Size Medium/Large

offers welcome NWT Max & Neo BLACK Nylon Buckle Martingdale Dog Collar Size Medium/Large WHAT IS A MARTINGALE COLLAR? The main difference between a martingale and a regular collar is that they tighten up as a dog pulls. This is not to choke a dog but to prevent a dog from escaping the collar. Many dogs have heads the same size or smaller than their neck. With a regular collar, when a dog backs up from up, it may be able to slip a regular collar. When this happens with a martingale collar, the collar tightens and prevents it from coming up over a dog's head. PROPER SIZING Our martingale collars are measured fully extended. When measuring your dog's neck, please measure near the top portion and press down through all its fur to get an accurate measurement. Most people do not press down the fur to get a correct measurement, which leads to them over-measuring their dog's neck and ordering a size that is too large. The metal rings at the ends should not touch when the collar is on your dog. The nylon portion attached to the D-ring should be extended. If you pull on the D-ring and the collar does not tighten, it is too large and must be adjusted to smaller. GREAT FOR TRAINING A martingale collar also tightens if the dog is pulling on a leash. You can give your slight dog corrections, which will respond much better than wearing a regular collar. SIZING for Nylon Martingale: Medium/Large - Neck Size 16.25"-19"
