His owner says that he's a Quarter Horse, that didn't make it to a horse (so quarter pony), but I don't know about that. Here's some pictures, and please help me figure it out.
(Tell me if you need more pictures, I have a ton)
Personality: He's really calm on ground, riding he's a bit hyper, but that's only him. He rarely spooks. Has tiny feet, kind of like some Quarter Horses. I don't know him well enough to go into detail. He's always very willing.
