The Halti® headcollar is based on the simple principle that if you guide a dog's head, the body will follow, controlling the dog quickly and effortlessly. It stops pulling, simplifies training and has an unconditional guarantee. Size 3 is for dogs the size of Boxers or Labrador retrievers. Size 4 is for dogs the size of Rotweilers or Newfoundlands. Size 5 is for dogs the size of St. Bernards or large Great Danes.
