I don’t particularly want to rehash this topic, but Zanhar found a video that represents what Western Dressage should really be all about, in my not so humble opinion. There are some mistakes in the movements on the first part of the video in the ride, mistakes often made in Dressage as well (and Western riding in general), but still far more representative of what Western Dressage should be all about if we require such a discipline. The second part of the video is near flawless.
I could get behind the discipline of Western Dressage if it looked like this. Anything else is hogwash.
