Almagron, wow all I can say is that I hope a child never enters or is around that horse. Its a good thing horses don't get put down as easily as a dog for harming someone.
I don't know why she is the way she is, I don't know her past. All I know is what I can do for her in the time she is with me. This can be anywhere from a week...er sometimes 2 days (we recently had one die after having him 2 days) to a few months (typical) to a few years (we only have one horse we have had for 4yrs now)
