I'm afraid that is not typically true. Any animal that has been taught a trick for a treat may sometimes perform the trick looking for the treat.
I have a paint mare in for rehab that knows how to bow. The reason I know is that one day, about a week after she was here, I was giving another horse a piece of Alfalfa cube (that is what I use as a treat), and the mare went into a deep bow all on her own.
I bought a horse last year that was taught to rear on command with a rider on her back. It looked very cool and the horse was a gaited, black and white pinto. Unfortunately the horse would rear any time he wanted to refuse something. That horse went back within a few days. (this is a picture of him with his previous owner) Shadow w mask.jpg
There is nothing wrong with teaching your horse to do tricks, but you must be very aware that, no matter what you would like to believe, that horse may perform the trick on her own.
