I have a TB that was retired from the track and was rescued from a feed lot. He is very smart horse and want to use him for a trail rider. He has spent very little time on the trails. I have been working with him for a couple months to get him where I want him to be mentally. But after reading your post I am begining to wonder if I should think about getting a different horse. Is that my best bet? Cause he has came a long ways in the few months that I have had him or should I continue to working with him?
