Many draft horse breeds, such as the Shire, are easy keepers. But, they are susceptible to obesity and other health problems, including laminitis and metabolic disorders if they are overfed with too rich a diet. Draft horses are usually large, strong animals. They have long legs and big bodies that give them great strength and stamina. Draft horses can be very intelligent and trainable. The first draft horses were developed in the 18th century, and they were used for pulling wagons. This gave rise to the term “draft horse.” Today, draft horses are used in a variety of jobs, including pulling heavy loads or equipment, driving plows, and for farm work. Draft horses are also used for horse shows and racing.
