I feel that the big time horses (im talking quarter horses because that what I do) are too big for their own minds. They don't understand their own limits or where their feet are. All they know is to move according to what they are allowed to do. English horses the big 17hh horses I find move over themselves. They are certainly too big for their own thinking. Breeders are breeding only for height now. They are forgetting about the horses mind. Like for example. Invest, Art, and Invitation are all nice bloodlines. They are HUGE. But you notice when you see them shown English, they are moving way too much over themselves. They move ah-head of their thinking. Personally I like the Zippo bloodlines because those horses move to themselves. They seem to understand where and how they are moving. Invest, Art and Invitation seem to just move without thinking. What I found changes that is groundpoles. It forces the horse to think about where its feet are. Also it forces the horse to carry itself better. So, what if you have a horse that moves over itself? It makes sense to me that groundpoles could fix that.
