The most comfortable head halter. Faster acclimation means easier training and happier dogs! The Comfort Trainer Head Halter will help you to gently control and train a dog that pulls, lunges or is aggressive. The Comfort Trainer's soft, rounded nose band will fit any dog from a Boston Terrier to German Shepherd to Mastiff, and will gently guide your dog's head and help you to quickly train your dog. The head halter conforms to your dog's head shape without irritating the eyes, constricting the jaw or hurting your dog's nose. Because he or she is comfortable, your dog will acclimate faster and be ready to learn. Why choose the Comfort Trainer Head Halter: Powerful yet gentle control to deter pulling, biting and barking or for walking multiple dogs. Very comfortable for dogs. The adjustment will not loosen. Dogs acclimate to it more quickly than some other brands. There is less chance of abrasion. Easy to put on and take off using the EZ-clip. Will not irritate your dog's eyes (if sized/fitted properly). Will not come off of your dog (if sized/fitted properly). The Comfort Trainer comes complete with instructions for use. Please note: It takes time to teach your dog to be comfortable wearing any head halter. You will receive instructions on how to do this. If you have only minor problems with pulling, you may consider a No-Pull Harness, which most dogs accept more easily. Not for use with a leash longer than 6 feet. Works best with a lightweight leash (like our bungee leash in size small). Customer Comment: "I have to say I find the Comfort Trainer highly superior to the Gentle Leader. It is perfect for us, I am most happy with it." - Judy Sizing: Note: If your dog's head is smaller than his neck (such as Dobermans, Collies and Greyhounds), choose one size smaller.
