Prevents pulling The Head Halter is a comfortable and humane way to prevent your dog from pulling on the leash during walks and other situations that require control. The head halter fits around your dogs head and nose (similar to a horses halter). It is not for use as a muzzle. This prevents choking and reduces your dogs urge to pull. By using a headcollar like this one, you get maximum steering efficiency. Walking your dog becomes safer and more pleasant for both you and your dog. Comfortable and safe Unlike other headcollars, the Head Halter is designed with soft neoprene and padded for maximum comfort for your pet. It offers a safety strap that attaches to your dogs regular collar at the back of the neck - no more dangling safety straps. It has durable nylon straps and strong stitching. Our design features additional reflective stitching to help keep dogs of all sizes safe. Easily adjustable and secure fit A quick release buckle and adjustable fit make this quality harness a secure solution to unwanted behavior with your pets safety in mind. It provides a plastic clip under the chin to easily adjust the loop for the snout. Adjustable side straps (size 1 does not have adjustable side straps) and an adjustable neck strap make for a better and more secure fit. This ensures that the halter does not slide off easily and makes it easy to put on any dog. Choose the right size To ensure the best fit with our no-pull head halter its important to measure the snout and neck circumference at least twice, using the instructions pictured, and choose the smallest result for optimal fit. The sizing chart is in the third picture. The halters have adjustable neck straps, side straps and nosebands (size 1 does not have adjustable side straps). The halters do not fit short-snouted breeds like Boxers, Bulldogs and toy dogs like Chihuahuas.
