The Olympics eventing dressage is currently on and the commentary is excellent, very informative. It's at an advanced level so includes extended and collected paces, half passes, flying changes etc most amateurs don't manage to train to that level. It's well worth a quick look if anyone is worried that dressage is cruel, unnatural etc It's also a good opportunity to see how spurs are used, they don't touch the horse unless the ride turns the heel in to give an aid and if they injure the horse in any way, just a tiny spot of blood and it's elimination, so they are always used very carefully and properly.
