One thing that can get conflated is what “competition dressage” means. The pitfalls, errors, and indeed strengths are very different between low level local ammies, high level ambitious pros, and top pros on the international circuit. Different horses different timeline different competition goals and very different riders.
I certainly get to see my share of clueless ammies and small time trainers hauling horses into a “frame,” choking off natural gaits, riding on the forehand, and blowing hind suspensories before they ever show First Level. I am not going to conflate this with other critiques I may have of horses going at FEI competitions. Different worlds.
Just like whatever you might think about Grand Prix jumping, it’s not fair to look at a timid adult ammie rerider thumping over cross poles and say “that is what is wrong with jumping today.”
