This reply comes from first hand experience on having a green horse.
I bought a green horse in December, to bring along. It has been A LOT of blood, sweat and tears! I watch my barn mates going around on their “made” horses, having their enjoyable lessons and am very envious. I wonder if my decision to go “green” was such a good one. I imagine when you finally get to the point that it becomes enjoyable, it might feel like an accomplishment. At this point, I don’t see any light at the end of the tunnel. I bought a green backed 6 year old and let me tell you, six is still very mentally young. I have a good amount of experience on horses and I really miss the reliability of my last horse who came to me well broke and just needed some edges smoothed out. There is something to say about the confidence a well broke horse can give to a beginner rider and also the fear a green horse can put onto a seasoned rider! My suggestion- don’t go green this time, keep it for the environment!!!
