The Beau Pet's Gentle Leader Head Collar is the No.1 Headcollar recommended most often by leading Vets & Trainers
 
When your dog pulls, the Gentle Leader gently moves his head and body back towards you. This effectively refocuses his attention back to you and off the distraction. Unlike a muzzle, the nose loop gently moves your dog's head when he pulls, while still allowing him to pant and bark. The collar sits high on your dog's neck without putting pressure on the throat.
 
The Gentle Leader headcollar is perfect for keeping your dog under control, for everything from daily walks to vet visits. And you can easily train your dog to heel using the Gentle Leader with positive reinforcement training.

FITTING YOUR DOG
 
The Neck Loop should be snug (like a belt or a shoe) so one finger can barely fit between the strap and neck and will not rotate. It must fit as high on the neck as possible, directly behind the ears and above thew Adam's apple in front. The snugger the Neck Loop, the looser the Nose Loop can be.
 
The Nose Loop should be in front of your dog's eyes and behind the corners of his mouth. It should be loose enough to move freely toward the fleshy part of the nose but not so loose that it can be pulled off the muzzle.
 
Be certain to check the fit everyday, especially on growing pups: Is the Neck Strap close-fitting and snug high behind the ears? Is the Nose Loop comfortable and reaching to the fleshy part of the nose, but not so loose that it can be pulled.
 
After you dog has reached his full growth, you can remove any excess length of the Neck Strap. With the headcollar off your dog, cut the strap with scissors and use a flame to seal the cut edge and prevent fraying.
