Wow gypsy, I don't usually call people out on things, but wow. Really? If OP is lucky enough to have a good solid relationship with her horse and they can jump together then KUDOS! Its called a solid relationship. If you have a blind horse and you lack that, you have nothing. A blind horse IS dangerous, same as ANY other horse, WHEN they don't trust their riders, plain and simple. The stakes are only higher because they rely on us to tell them where to go, how high to step, how fast to go, or how high to jump.
I own a blind horse, and trust me, we do everything we have always done, but actually even better, since she actually has to listen to me now and she can't be the hot headed barrel horse she used to be. I wish she was younger, I would definitely still compete on her! To have a relationship like that and have a horse have 100% total faith in you, that is a once in a lifetime experience.
Back to OP, kudos. Its not easy to do. Maybe I missed it, but how did yours lose its sight at so young an age?
