I have purchased a few books recently on the theme of horse behaviour and the relationship between human and equine. This is in my opinion by far the best, most clearly explained book and whilst it advocates ensuring that training, riding and keeping horses should be as natural as possible, it doesn't attempt to persuade the reader to adopt the techniques of a particular trainer (although one name did come up a few times, but it wasn't overdone.)
I am fascinated by horses and ride whenever I can. If at some point in the future I am lucky enough to be in the position to become an owner, this book will be my 'bible'. I'm a novice but I've always suspected that many of the training methods and the way we look after horses was inadequate and sometimes downright cruel. If you also suspect that there must be a better way, read this book, you won't be disappointed.
