I didn't answer because you said you were interested in English riding training, and the things that have interested me were more 'western' or just general horsemanship focussed.
I would say that at some time you should read "True Horsemanship Through Feel", by Leslie Desmond, regarding Bill Dorance. It is, however, very hard to understand if you have never been exposed to this sort of approach, and is written in his vernacular, so can often be confusing.
A student of his, Marty Marten, wrote a very concise and well illustrated book called, "Problem Solving". It was published by Western Horseman magazine. It is not just for solving problems, but for learning how to set things up so problems don't happen. It has well illustrated excersizes for ground work.
Again, I lovedd this book, but it has no link to English riding or dressage AT ALL. there is nothing about inside or outside reins, riding back to front, or any of the other stuff you learn in lessons. IT's about how to handle your horse on the ground, and how to build confidence in your hrose for riding out on the trail.
Mr. Marten passed on just a couple of months ago, at only 71 years of age. sad.
