I see MAYBE a little bit sickle hocked. With is NOT necessarily a bad thing. I actually prefer a horse to have a little bit of a sickle hock because with the disciplines that I do, I can get a really good stop and turn.
There is something going on with his back legs from the hock down. It looks...weird. Also his back left leg (the in butt picture) toes out in a pretty extreme fashion.
His cannon bones on his front legs a pretty long. He has nice pasterns.
He has a very sweet face.
He is butt high right now. But there's a good chance he could grow out of that.
He looks posty and cowhocked in the back legs but not terribly sickled.
It's suprising how many horses, especially QH's and Paints, are sickle-hocked to some degree.
I've even seen high point earning show stallions who weren't ideally correct in the back legs. Being a tad sickle-hocked isn't a bad thing, it is when they are sickled to the extreme that you want to worry.
