Interview with Ernst Bachinger, former Director of the Spanish Riding School in Vienna.
"What do you do if you see a brown spot on the white coat of one of the stallions right before a presentation?"
"Well, they wouldn't have any spots before a show, at least not without any of the grooms getting in trouble. But generally, you can rub a piece of coal on the spot and then brush it off. If that doesn't work, then pull out that piece of coal again - and he'll be (dapple) gray for the day."
