My daughters one eyed barrel horse Left Eye is quite the girl. She is easy to take in to the arena, will calmly lope, change leads, do circles, stop, start and behave herself, even with barrels in the arena. However she does get super excited when others around her standing outside the arena start getting silly and running. I sometimes wonder if its because she doesn't see out her right side and can only hear the excitement around her and feel the excitement from others. At that time, my daughter needs to back her towards the gate, then she will turn around and run, then finish her pattern, stop and walk out.
Alot has to do with her training before she was purchased by my daughter and since she is very ridable and workable like this, no sense trying to change it now. She is 20 and pretty settled in her ways, why mess with it since it works
