A halter or headcollar is headgear that is used to lead or tie up livestock and, occasionally, other animals; it fits behind the ears (behind the poll), and around the muzzle. To handle the animal, usually a lead rope is attached. On smaller animals, such as dogs, a leash is attached to the halter. History Halters may be as old as the early domestication of animals, and their history is not as well studied as that of the bridle or hackamore. The word "halter" derives from the Germanic words meaning "that by which anything is held." Uses A halter is used to lead and tie up an animal. It is used on many different types of livestock. Halters are most closely associated with Equidae such as horses, donkeys, and mules. However, they are also used on farm animals such as cattle and goats and other working animals such as camels, llamas, and yaks. Halters generally are not used on elephants or on predators, though there are halters made for dogs. Halters are often plain in design, used as working equipment on a daily basis. In addition to the halter, a lead line, lead shank or lead rope is required to actually lead or tie the animal. It is most often attached to the halter at a point under the jaw, or less often, at the cheek, usually with a snap, but occasionally spliced directly onto the halter. A standard working lead rope is approximately long. However, specially designed halters, sometimes highly decorated, are used for in-hand or "halter" classes at horse shows and in other livestock shows. When an animal is shown in an exhibition, the show halter is fitted more closely than a working halter and may have a lead shank that tightens on the head so that commands from the handler may be more discreetly transmitted by means of the leadline. A shank that tightens on the animal's head when pulled is not used for tying the animal. Halters are designed to catch, hold, lead and tie animals, and nothing else. However, some people ride horses using a halter instead of a bridle. In most cases, it is not safe to ride in an ordinary stable halter because it fits loosely and provides no leverage to the rider should a horse panic or bolt. It is particularly unsafe if the lead rope is used as a single rein,
