Book excerpt: Have you ever wondered what your horse was thinking? Or how to stop his bad habits, whether that's over eating, biting or bucking? How do you plait manes and tails? Why grooming is necessary and how to do it properly? How do you change your diagonal or how long your stirrups should be for jumping? Divided into three sections About Horses, About Riding, About Me, Pippa's essential guide to all things horse and pony related is written with her characteristic warmth, humour and wise words.
