All right, if that is your horse, I am seriously jealous. What a beautiful animal!
I'm better at figuring out what he's not. Not a Trakehner. Not hairy enough for a draft cross. He could possibly be an appendix QH, but he'd be an extra special one if so. Someone on another board has some Latvian horses, and he looks more like them than anything you'd normally see in the US. Just my humble opinion--I'm far from an expert.
