Soenjer55 thanks for that awesome photo! Okay now I can see what a steep croup looks like.
I'm going to look up skookum horse and two eyed jack as well. It would be nice to even have an idea. Thank you for those suggestions!
Yes he does have a very big head. It's not just the angle of the photo. His head is that big! Lol. His face always has that sweet, sleepy eyed, kind of dopey look too, which I love.
