Horse Collars: before horse collars they use to use cows and buffalos, were trained to pull heavy things like carts and wagons. Horses were used but the yoke was not appropriate for the horses, but even though the horses were used, they get tired and did not do as much work as buffalos and cows horses were not as useful. And more animals meant more costs. How was it invented? Well like a lot of things it was invented in China. China developed breast collars. Its main weakness was that it made the horse pull the load. And eventually the Chinese invented the horse collars around 475 A D.
I like that horse collars were invented so people could go places and have fun!!!
