ESH, the question wasn't directed to me, but I would like to answer. First of all, there is a lot that you can tell from a picture. I always tell people I am far more impressed by someone who can walk beautifully than someone who can do sloppy canter work and "stay on". Going beyond obedience, there wasn't anything "quality" that I saw in any of those horses. Good work takes time, and to say two weeks for a 7 yr old horse that you have never seen and has never had a saddle on is not fair to the horse. I don't only want people to participate in training, I want the horse to as well.
He shows no interest in the physical well being of the horse, no interest in saddle fit or proper balance and movement. Those are all things that are apparent in those photos. We tend to think of "abuse" as not feeding, or striking, or losing patience, we never think about what we might be compromising beneath the skin just through lack of knowledge on how things work. I have seen far more abuse and permanent damage done by people who love their horses to death and can't ride than people who hit their horses. I personally want more from my horses than obedience, I want them to look good and FEEL good doing it. I don't use my "buy one get one free" deals on the horses well being.
As far as the second trainer mentioned, there is no way to tell from that bit of information. It doesn't sound like much from that e-mail, but you never know without seeing. I personally speak much more boldly on forums than if you were to call me on the phone, however, whenever I get a call, I do offer to do a demo or a consultation on the horse they are asking about. I won't talk about myself when spoken to directly, but have no problem letting people figure it out for themselves by watching, so I try not to judge other people by just what they say, knowing how shy I myself can be.
