She is spotted (black and white tobiano), which I know a lot of the gaited breeds come in a spotted form.
She looks A LOT like a Tennessee Walker in build and her head, especially.
She does a nice running walk...but she also has another gait that is kind of...odd. She looks like she's trotting with her front feet, but cantering with her hind. It is almost similar to the paso fino's corto gait, but is more extended and not nearly so short-strided and "choppy" looking. I'm not sure how to explain it.
After doing some searching (as much as I can search on Wikipedia and YouTube...stupid computer has some sort of virus that won't let me use search engines and we can't figure out what's going on with it), she may be a spotted saddle horse?
Sorry, I don't have any pics of her. (FYI-for those of you that know about the horse that threw me about a month ago, this is the same horse...we're really just curious as to what she might be because she has such pretty movement...when she's not going off randomly bucking like a rodeo bronc like she did on the trainer today).
