I beg to differ.
If anything, it’s easier to get an accurate view of soundness with a rider’s weight on a circle on a loose rein.
The previous version of the jog was on a straight line with many horses who were reluctant to leave the in gate at a bright trot, which made it harder to assess soundness.
Plus the circle at the end of the round lets the judge decide whether the horse was sound at the time it showed, not hours later after it went back to the barn and wore ice boots or whatever in the interim.
While the traditionalist in me was sad to see the end of the jog in hand at the end of the class, it is certainly easier on both the horses and the people as far as logistics go.
When the horse is done performing now, it can go back to the barn and get put away for the day. It does not have to wait around with its braids in and come back up to the ring hours later for the jog. Or worse yet, wait around and come back hours later for nothing after it gets bumped off the standby list by the last trip in the class.
