I can get Jasper to relax and stretch(his head and neck) down a little at the walk, but anything faster then that and he consistently keeps his head quite high. He is a standardbred so it's expected, but I really want him to stretch down a little when I ask him to. He does the same when I lunge him without tack. Is there anyway I can teach him to stretch at the trot? Could it be a lack of muscle or his conformation?
This is about as low as his neck will go when we're trotting Oh, and by the way, I always ride him in a halter.
