... should read this book. Seriously. It's very, very informative.
It's only $13.57 on Amazon - http://www.amazon.com/Easy-Gaited-Horses-methods-training-pleasure/dp/1580175627/
Has anyone else read it? What did you think?
Side note -
Please make an effort to collect your horses and please stop allowing them to pace (ignore that part, Icey and STB people). Contrary to popular belief, just because it's gaited doesn't mean it has to move in such a stiff, destructive frame. Your horse might prefer it now, but he won't be feeling so good a few years from now.
