Nasty was a tame word to use for her, cutting her from the rest of the mares was difficult. A few men almost lost their heads, and the fences had some nice new dents. By the time she was in a small viewing pen, her flanks were lathered and her sides were heaving from the effort. Pacing back and forth in aggression at a brisk trot. Head high in the air and tail lifted and swishing back and forth. 

Snapping her teeth at the closest human face she could get to, hoping the more wild she acted the less a trainer would want her. The crazier she acted the harder it would seem to tame her, and not many people here seemed to be looking for a challenge. 

She squealed and bucked and brayed until she was shaking from the effort. Until she was sucking such large lungfuls of air with her head hung low and ears flicked off the side. Eying the two men warily.
