I don't think knowing something would make me deal with the horse differently, if you did your making the problem a big thing, that may not happen with you if you follow.
Example mine hates the schooling whip, I didn't think gosh poor lass someone has done something, that's irrelevant, what's important is our partnership and trust and its just one of those things to work on. Incidentally I don't believe anyone has, I think she has filed it under correct me at your own risk!
I took her on as a project, she didnt come ready made, she came with opinions, I have a long way to go, she is still green.
Having said that I knew she was a halter bolter, if you haven't met one of these, it means your leading along nicely and bang your horse less! They are gone, head in full pelt and you are on your butt-because the first few times your hands dont get time to let go! But, she took off up the lane when I viewed her and I skied behind! I was pleased because it allowed me to think can I cope and deal with this.
Dannii-i would walk away from a project if they didn't tell me the good, the bad and the ugly. It was nice to be told all the good points but equally all the not good that came as part of the package. I wouldn't change a thing about her because I wouldn't have learnt a thing.
