My friend Kelly in Texas found this book helpful. Here is what she had to say:
Easy-Gaited Horses, by Lee Ziegler. I have others, but this is by far the best. Lee Ziegler was apparently quite a guru among gaited horse people. She's dead now - way bummer - I think ovarian cancer. The book did help me better understand Ruby's gaited "wierdness" (you know her twelve different gaits, her initial failure to pick up the canter, her propensity to stumble at different times depending on what we are doing, etc.) so I have found it helpful.
