What we were told by higher level Multiples drivers, was that Standardbreds take too much work to get needed excellent results in Dressage. They are lovely horses, but long, lean body style is against them.
Both Standardbreds and Orlovs, are built for speed, bred the fastest to the fastest, got the great speed they are known for. This speed is attained going in straight moving ways, not bending, flexing, allows the huge overreach of the driving rear end. The best ones have a more straight, even rigid, spinal carriage in motion.
Stiff spine makes it VERY hard for them to be bending, flexing, while going forward. Not bred for bendable body. I have huge respect for the drivers who gave us this opinion. Heck, one of them showed an Appy at the World Pairs and WON!! Not a breed prejudice thing. Those guys will drive what wins.
So even though Standardbreds are very capable in pulling carriages, often kindly horses, very available, they take a lot of personal work, to get bendable. You must continue to work on the Dressage aspects, to keep them capable of scoring reasonably. I don’t know any who score VERY well, but could be missing some good ones. If horse is your one and only, has you to put in the extra time and work, he might be one like WA talks about. Most Standardbreds just can’t get the good scores. They are just not capable of moving the way judges want to see, not his fault, but his speed breeding.
More of the Driver needing to pick the correct body style, able to do what you want. Driving Standardbreds would seem to be a “natural” in CDE, but they are far from the most common breed used. If a horse can’t do a good scoring Dressage, it will hurt in the other sections. Raw speed is not really that beneficial on Marathon, since too early is penalized like being too late. Horse needs to be bendable for Hazards and Cones, so his job is easier.
ALL EQUINES must do the gaits required in Dressage. This would be a LOT of trotting, not gaiting. If equine can’t trot, he won’t score well. Same with Pleasure Driving. If trot is required in a particular class, equine MUST trot to be considered for ribbons. Performance classes, Obstacles, Games, where time is the criteria, are do-able with a gaited horse. Read your rules, know what classes in shows require for gaits.
Every breed can’t be the best at everything, despite breed publicity! I like gaited horses, but they were made first for riding comfort. Light vehicle behind, you can have fun. They just are not the best breed for CDEs. Why wreck a nice gaiting animal, trying to make it trot? Not what he was made to be doing. I love my big (over 16H) horses, but they would be very unhappy if I decided to make them competitive barrel, cutting or reining horses. Body style is not the most suitable, they probably will hurt themselves trying.
