∟Horse Breeds A-Z: American Quarter Horse
"The breed originated in 17th century colonial Virginia using English Thoroughbreds crossed with a variety of local tribal animals. Local horses available to the colonists were of mixed Spanish descent, carrying traces of Andalusian, Barb & Arabian blood. The resulting crosses were small, stocky animal with muscular hindquarters. The origins of their name, Quarter horses are prized for their explosive speed over the quarter mile. Their versatility was a huge element of their success as a breed, as they could work during the week & race on the weekends. Due to the many different bloodlines that were involved in creating the Quarter horse, there are a variety of breed types. The squat robust animal with powerful, rounded hindquarters is just one type of this versatile breed.
Stock Type
The Stock type is small with powerful hindquarters & quick, agile movement. Built to work cattle & respond quickly. Western pleasure show horses are often taller with smoother movements, but still feature the large hindquarters.
Halter Type
Halter horses have a specialized look, they are larger than the stock type & very heavily muscled. Taking the quarter horse aesthetic to the extreme, this type is bred to be muscular with small heads, large jowls & refined muzzles. There is controversy about how healthy it is to breed for such large muscle mass on the equine frame.
Racing Type
This type leans more towards the earlier animals of the eastern seaboard, heavier on the Thoroughbred influence for speed & agility. The racing type tends to be larger & leaner with longer legs. All the while retaining their powerful hindquarters, built for speed rather than the quick, short movements of cow horses.
Hunter Type
The hunter type also relies more on early Thoroughbred influences & tend to be even slimmer than even their racing counterparts. In the English show ring, their speed, athletic ability & agreeable nature makes them a natural choice." -TheEquinest
