If I were a horse I think I would have been the result of experimental breeding, probably bred for endurance or competitive trail. I'm a grade that ended up tall and lanky, 15.2-16hh. Based on my hair and eye color in real life I'm thinking I would be a blue eyed, bald faced dun. People might ooh and ahh over my color at first, but it will be pretty clear right away that my color is the only thing good about me. I've got the horse equivalent of asthma, useless ovaries, a bad back, bad knees, bad balance and coordination, and bad eyesight. But don't count me out yet, I can be bossy and want my way all the time but I'm non-confrontational and will bow out and become a very polite and respectful horse in the right hands.
I think I would end up a good family horse. With regular chiropractic care and light riding I will flourish. As I get older I'd make a good babysitter, I'd enjoy taking people out for the occasional weekend trail ride and enjoy a good walk around the yard with a child on my back.
I would definitely be an ideal first horse for a young kid as I got older, but I wouldn't be and would never have been enough to take anyone any further in the equine world than that. I'm a trail horse recommended for very light riding only.
I didn't think that would be quite so long, but anyway, there's the game, have fun with it. C:
