I have never thought of good horsemanship as a discipline in itself. In my mind, it has always been a foundational element of everything we do with a horse.
I am very pleased to see that nowadays more people are teaching the importance of taking their horse’s opinion into account during the training process.
When I was a kid and working at a riding school owned by dressage trainers it was a golden rule not to rein back a horse until it was well established in all the forward paces and shoulder in.
