That mare works cattle quite well. If she did not she would not win like she does in NRCHA. Only time that mare has lost a class was in the mud and well she hates mud. Never shows well in it.
As for the ears. They are always like that. She has them pinned about 24/7. Just her things like most dun it mares.
Case in point.
Like I said a Dun It will not make an NCHA Open Futurity horse. Heck even horses bred out the rear to be cutters do not make NCHA Open Futurity horses. However what they do make is a NRHA Open Futurity horse and Non pro/green Reiner horse and they do very very well in NRCHA. If you go back just 2 generations they where bred to be cutters. Only reason why they went the reining rout was simply location.
If this mare did not have cow she would not have done as well as she did. I know horses trained just as well as she is that do not even place at NRCHA shows.
