I don’t ride dressage, but I laughed a lot at this thread! Too funny.
Unless I am jumping, I try to stop when the horses poop, to make the subsequent picking of poop easier (we have $$$ footing in both rings). There’s nothing worse than a “traveler”. It never occurred to me that I might be installing a woah.
My horse almost never poops in the ring, as she is a dedicated crosstie pooper, but when she does, I stop to “consolidate” the pile. I have a pretty hot/forward horse, but when she poops on course, she slows to a crawl and requires a LOT of leg. Since she is so hot to the fences, when I complain, my trainer yells “use it to your ADVANTAGE!”
