No, I do not do training, I am like you and am trying to do it myself. I took my time went slow with her and made sure I spent a lot of time on the trail to expose her to everything. She is now a great trail horse and I can even get her to do the indian shuffle. Interesting gait to say the least. I noticed that a diet of steady riding and she does great, Winter has been cold and riding has been sporadic and she is a bit more uptight when out on the trail now. Nothing that some nice weather and lots of miles wont fix. I spend 75% of my riding alone and for a four year old to go out alone I think it is pretty good. The Nokotas I have found in my limited experience will be open to anything you ask once you have gained their trust. I have done a lot of work with her to respond to leg pressure and in the arena at a walk, you can drop the reins and move forward, stop, weave in and out of obstacles and all manner of different things like that. My goal this year is to be accepted as a contestant at the Versatile horse challenge(extreme cowboy challenge) at the Equine Affaire in Mass. We have some work to do, but that is part of the fun. I have to give a lot of credit to my wife for helping me. She has a LOT more riding experience than I do.
