He looks Morgan, or at least part Morgan, to me. His face and body are very Morgan-like. That compact body with strong limbs is very typical of the Morgan.
I'm not sure what tinyliny is referring to as far as curly mane. I've never seen a Morgan with a curly mane? I'm sure they exist, but I don't think it's a breed standard?
I only have limited experience with Morgans, but from that bit I have, and from what I've read, they are very intelligent and curious horses, always aiming to please, and enjoy the company of people.
Generally easy keepers, so be careful what you feed. Usually very strong feet, though.
I love Morgans
My boy is only half Morgan, but he has a lot of the standard characteristics of one.
