I can't tell you anything about how well he'd be able to chase a cow, but overall, I like him a lot. He's big and sturdy, that's for sure- nothing glaringly wrong. I love how he's put together, everything is balanced and proportionate... pasterns and canons are nice and short, and the angle looks okay. His back legs look good to me, although I can't really see them... nice big motor, with a huge hip and good length of back, a decent shoulder and a decent neck set. Like I said, I really do like him.
Correct me if I'm wrong, but aren't cow horses usually a bit shorter than this? Will his height effect his performance/ ability to get down and move?
