If she is gaited and could take time to come out in her. Then again I know a flood blood registered Tennessee Walker out of show lines, that won't gait any. The best way to pull a gait our is to ride with other gaited horses. Normally we use at least four other horses, and get one in front, one on each side and on in the back and all start gaiting. You got to make sure you have an exit, if she does anything crazy. Now, that doesn't always work. If she does have a gait, mostly likely a flat walk she is most likely Spotted Saddle Horse or mixed. I love the breed and personally think they are calm horses for trails, but I wanted to barrel race so I no longer have as many gaited horses, we have one show bred Tennessee Walker.
