Couldn't say for sure. It might have something to do with whether they are mini horses or ponies. There is actually a difference, I don't remember the exact differences of the top of my head, but it has to do with body proportions.

Yeah, these were mini horses. I think mini horses have the same proportions of big horse(just tiny) whereas ponies tend to have their own proportions that are bit different.

The mini horses I've seen are flexible as hell though. Bend themselves in half to scratch an itch on flank with their teeth.
