Working with long reins is an ideal and, above all, safe way to break horses to harness, and to train the driving horse correctly. This book is an essential training book for all drivers and horse trainers. Heinrich Freiherr von Senden, a successful driver and horse trainer, has developed a structured training programme. Beginning with work on the single lunge, moving on to long reins and then on to the initial hitching, he gives tips and advice from his accumulated wealth of experience, explaining how potential problems can be successfully resolved.
