Something about the way he moved in the trot video jumped at me; has he ever had an injury to his right hind leg\hip? It almost seems like he favors that side a bit...
At any rate, just because he's 'pleasure' bred, DOES NOT mean he can't do dressage, at all! You can actually improve how well he moves in your western events by teaching him dressage movements, even simpler ones like a shoulder in, shoulder fore, or how to lengthen his strides. Everything about dressage is about helping a horse learn how to use his body MOST effectively; and if you can help him learn that, you will do even better in your other events.
Not the right - he got kicked about a week and a half ago on his left hip, though. And he was favoring it a bit. He had a nice gouge out from the shoe the other horse was wearing, too. I don't notice that he's favoring it from riding anymore (he was for 3-4 days at first) and nobody else has commented, though. I'm going to watch the video again.
We plan on working with dressage. What I'm asking for in the video is western pleasure movements, but I want to round him out in the future with a bit more leg action from him
