So my question is simple, can a horse really be a "one person" horse? I only ask, because of this other horse that I tried out (that threw me off) at the place I tried Flash at. Basically when I got off, the owner who is only 23 years old told me that it took her 3 months to be able to ride her because she had to get used to her voice. She hopped on her for a few minutes, basic W/T/C and hopped off and didn't have a problem. In fact, this mare had beautiful gates. But when I hopped on, she started bopping her head and then I lightly tapped her and she picked up a steady trot and got faster, and before I knew it she was at a full gallop and took off with me. I went around the ring probably 3 times in a matter of 15-20 seconds.
Now my thing is, do you think this horse really is a one person horse and needs to really get used to me? Or was it a case that she was just testing me as a horse to see what I was like, how I handled her, etc? Or is she just a horse that really isn't used to more than one person?
She was a polo horse for a while (she's 11 now) and was abused, and this 23 year old does seem pretty knowledgeable but she doesn't have the money to care for the horses right now and she says she wants to give this mare away before she gives away Flash. Now that's not to say I'm going to take this mare and she'll be mine and be done with it. But Flash is only a lease and after 6 months-1 year if she decides that she wants to show him she's going to keep him.
So that's basically just a question I'd like to know. I might sound crazy but would getting a trainer to help me work with her be possible?
I'll take all the opinions I can get! Thanks!
