Thanks so much everyone. Awesome advice, and I should get a chance to try it out next week. I'll let you all know how it goes.
I just like doing any learning process with my mare, she is SO willing to learn. It's fun for both of us...she has always run up to the fence when I go see her, but now she's getting to the point where she's like, "Hey! Where's my halter? Let's do something!" Which is really neat, because I can already see such a difference in her when I got her in January. But sometimes I can definitely tell she wants a job to do, which I think is pretty normal for horses. I just figured this one might be a fairly harmless one for us to try.
LoL, I'm sure I'll be posting more and more questions as time goes on...as long as she's willing to learn and I have the ability to teach her, I sure don't mind trying.
