What is "jigging"?

Jigging is a bouncy pace halfway between a walk and a trot. A horse generally jigs because they are anxious or nervous or because they are over excited and want to get going with whatever the job of the day is. It can sometimes be hard to tell which, but the correction is generally the same - to release the rein slightly and use your voice to try and get the horse to relax. A horse may also jig through a downward transition - this is not correct and judges will mark it down in the show ring. A horse that has the habit of jigging a lot is a "jiggy" horse.
