A head halter is a type of dog training tool designed to help control a dog's head and prevent pulling during walks. It fits around the dog's muzzle and neck, allowing the owner to guide the dog's direction more easily. This can be especially useful for larger or more energetic breeds that tend to pull on the leash. Head halters work by gently steering the dog's head, which in turn influences the rest of its body. They are often recommended by trainers and veterinarians as a humane alternative to traditional collars, promoting better behavior without causing harm to the dog.
