I have whole two years of experience
. I am living in quarter horse state
and people here in Amarillo don't have lot of experience with gaited horses either. My trainer of horse riding couldn't identify what kind of gaits Babe was using.
Is hard to find specific sources about MFT but try to get this (I ordered few days ago on eBay for 5$
The Missouri Fox Trotting Horse Its History, Versatility and Gaits VHS training
There are other sources of knowledge on DVD on gaited breeds:
Jennifer Bauer-Gaited Horsemanship-Riding the gaited horse and part 2-Lungeing the gaited horses
Larry Whitesell-in hand training for the gaited horses; Under saddle work: riding the gaited horses; Ride a better gaited horses
David Lichman-Gaited horses, naturally! How Parelli natural horsemanship applies to gaited horses, part 1 and 2 (someone is selling them on eBAy right now)
Anita Howe-sells her books and DVD about gaited horses on eBay. I got one about intermediate gaits but ..somehow can't get more than trhu few pages.
Brenda Imus-DVD and books-very general and in my opinion not worth, unless you just need basics of basics.
Clinton Anderson-Gaited horsemanship-concentrates more on general problem with horses, not specifically gaits. But if you have spare money, worth to have. I started watching some time ago, since he demonstrates progress with two TWH mares; one going forward, running out, and one one lazy. I watched about the first one, because her behavior was exactly what I was dealing with in Babe; not listening to reins, not stopping, speeding up.
There is good book about basics of gaited horse plus with chapters about specific gaits, how they look ;
