Just to give you a picture of what he looked like before, imagine a camel's neck. UCK!!! He has tried to rear WITHOUT side reins (he didn't get very far, let me tell you:)!), and he does not have enough muscle mass or incentive to try to rear.
Anebel: Sorry, but we were in a sixty-foot round pen, Sam was very relaxed, and my own mother was standing right there, the only reason we tried riding with side reins was because we know his attitude and how lazy he usually is and how he hardly ever puts up a fight. Impulsion? He was trained as a race horse, and he has NO impulsion.
He is thirteen years old, according to his tatoo.
