"I don't understand why you wouldn't want to be able to do that."
Hm. That's funny. I think I specified already that I would LOVE to be able to do that. Its not as if I'm deliberately trying to make her so closed off from others that she will reject every single person except for myself. I'm just not that self interested nor naive to feed into that paradigm. I'm glad that your horse has had 50+ riders on him, he's been able to win ribbons with all riders no matter their skill level, and you have had the ability to socialize your horse in such a way.
Don't get me wrong, I've worked with such horses and they are a pleasure to be around. After being a trail guide for over seven years, I get that joke. My other mare is just such a horse. She will allow anyone to work for her, but she gives that so called "little extra" to me. But this isn't about that. It is merely about how I can go about acclimating Rosie to people and a world she has scarcely seen.
I find it extremely ironic that this disservice I am subjecting her to is in fact the complete polar opposite of what I am attempting to accomplish. That being, providing her with a happy and safe environment where she can live out her years and flourish. God forbid!
As I have stated previously, I DO worry about this. I understand that having a horse that is so one-person-oriented is an extreme drawback. And again, this is why I came here. I did not come here for criticism on my relationship with my horse. I did not think this question would be met with a barrage of "you are treating your horse poorly because you......"
I know this is rather harsh. But I really don't care.....I came here for advice, and a number of you have helped immensely, thank you so much. Your insights, stories, and tips have given me a better perspective on the matter.
