I'm new to the forum and have a three year old Shire Percheron cross. I've had him for about a month now. I bought him green broke and, after a vet approval, have begun short light rides and lot's of ground work. I'm a fan of Clinton Anderson's type of training - am trying to go step by step through his book. The horse is flexing his neck like a champ already, from both ground and while standing when I'm on him. My questions is, as we continue to work in the saddle, how does he know difference between flexing his neck/one rein stops versus when I'm asking him to turn or steer? He hasn't had a bit of trouble with it yet, but I guess I'm a little confused and want to make sure I'm continuing to send him clear messages. Thanks! K
