What qualities of the jog are judged in walk-trot western classes?

The jog is a two-beat diagonal gait in which the horse's legs move in diagonal pairs — left front and right hind together, right front and left hind together — and it is the primary gait evaluated in walk-trot western classes because it occupies the most judging time during the class. A correct western jog should be slow, smooth, and cadenced with a clearly defined two-beat rhythm that is easy to sit and pleasant to watch. The horse should carry itself in a balanced, relaxed frame with a natural headset appropriate to its level of training, moving with enough energy from behind to maintain a consistent pace without the rider having to drive constantly, but not so much energy that the horse is difficult to rate or appears hurried. The stride should be ground-covering relative to the horse's size, with the hind legs stepping up and under the horse's body rather than trailing out behind. A jog that is too slow becomes a shuffle with no clear rhythm. A jog that is too fast becomes difficult to sit and loses the relaxed, controlled quality that western pleasure rewards. Smoothness is a significant factor — a horse with a rough, bouncy jog is uncomfortable for the rider and penalized in classes where the rider's ability to sit the jog is part of the evaluation. Consistency of pace throughout the entire class, including through corners and in close proximity to other horses, is as important as the peak quality of the jog when the horse is moving well.
