I was wondering what other people were thinking about that! It had me a bit perplexed. With the dark (gorgeous) horse that stopped after Kelly's you would have thought the horse won the class with the amount of affection it received.
I also find that while at home I will whack, a show isn't the time to discpline a horse, if it was a stop due to fear, confusion or rider error, in the show ring I'll give my horse a quick pat to calm my nerves and then go back to the course. However if it is imperitive to whack him once behind my leg I'll do so.
I dont know for sure because I didn't watch, but when my horse stopped out in a 3' derby, I was not mad at him because my horse never stops. He was panicking because of the crowd near an oxer. So...I patted him. No sense smacking a scared TB who has never stopped at a fence before.
That is what I've always been taught too and I brought this up while watching the MaClay I believe it was. (I don't remember the remark being too well received either) Horses are smart and if they get to just stop and get a pat they will figure that one out. It depends on the situation, if you have a horse that stops shaking at a fence then that is one thing but most of these horses know their job since they do it just about every weekend over different fences.
