Horse collar

Okay kiddo, sometimes people need to put a big strap around a horse's neck to help them pull heavy things like wagons or plows. This strap is called a horse collar. It is made of sturdy materials like leather or canvas so it can hold up the weight of whatever the horse is pulling. The horse collar goes around the horse's neck and is held in place by a harness that attaches to the wagon or vehicle. This helps distribute the weight so the horse doesn't get hurt or exhausted. Remember, horses are strong but they also need our help to work safely and comfortably.
