What is the definintion of a roping horse?

A roping horse has the job of running after the cow or steer keeping in the perfect position for the rider/riders to lasso the steer's horns. This can be done with a single horse/rider or 2 horse/rider teams known as team roping or more commonly 'heading and heeling'. With the 2 horse/rider teams, and the reason it's called 'heading and heeling' the steer comes out of the chute followed by the first horse/rider and then the delayed follow by the 2nd team. The first rider has to catch the horns (heading). Within a couple of seconds the 2nd rider has to rope at least one hind leg (heeling). The horses have to be as well trained as the ropers themselves and it is a difficult and demanding sport. But it is so much fun to watch. Like with most things, the horse/rider teams that are really good make it look easy.
