The Gentle Leader Headcollar is a perfect no-pull solution to help improve leash manners and the bond between you and your dog. Designed by trainers, the Gentle Leader Headcollar is loved and trusted by vets and pet parents and has helped improve 5 million walks around the world. This training tool is best for dogs who pull because it interrupts your dogs natural instinct to pull against pressure. The headcollar loops around your dogs nose, so when he pulls, it gently moves his head toward you so he can refocus his attention on you and away from other distractions. Although this training tool rests on your dogs snout, it doesnt work like a muzzle. Your best friend still has the freedom to eat a treat, drink water and catch a tennis ball at the dog park. The quickest way to help your dog feel comfortable wearing his new headcollar is to let him wear it without a leash attached while he does all his favorite activities. The best part is, once your dog is a champ at walk etiquette, you will probably only have to use the headcollar as a backup during situations when you need a little more control, like visits to the vet. This headcollar wont fit our furry friends with super short snouts (like pugs or bulldogs). If you have a dog with a short snout, check out our Easy Walk No-Pull Dog Harness. You can purchase the Gentle Leader Headcollar risk-free because whether the headcollar isnt the right size or your dog mistakes the harness for a chew toy, our Customer Care team is happy to assist you with a new size or replacement. You and your dog will soon enjoy pull-free walks together. Trust PetSafe to help keep your pet healthy, safe and happy.
