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.
