An acquaintance of mine once trained thoroughbreds, with moderate success. I asked him once if the track stewards ever questioned him after a horse of his showed suspicious improvement in a race...as the rules say they should. He told me it only happened once...but he was prepared and had a ready answer for them.
"A little goat wondered into the horse's stall the day before the race, and my horse perked right up. It was the strangest thing I've ever seen"...he told me that he told the stewards. And it worked like a charm.
