Most barrel racers use quarter horses. The quarter horse is a breed that originated in the United States and was originally used for racing. They are considered the fastest horses over a quarter mile. They have great speed over short distances, and they have been bred to maneuver well around turns and obstacles; this is why they are a popular choice for barrel racers.

Contrary to what some people believe, not every horse is an ideal candidate for barrel racing. Though there are fewer particulars than there are when looking for a Thoroughbred that will be a winner on the race track, there are a number of different characteristics that will be found in great barrel horses. Temperament can play a role in the success of barrel horses just as much as the horse's skills, character, training and lineage.

You read that right - even with barrel horses, you'll find that one of the major considerations that many buyers have is the lineage of the horse. A barrel horse's bloodlines can help to identify how successful past generations in the line were, what the horse was bred for and can provide a sense of what the horse will be able to accomplish during the race.

Of course, more than the bloodlines, most buyers find that, with barrel horses, it is about the build and health of the horse. A good barrel horse has legs that are straight, and if you're buying a horse that's already been raced, you will want to be sure that its legs are free of any bumps or external scars. It's important to be sure that the horse's hooves are healthy, that its back is strong and that the horse is flexible and athletic.
