He is bred for WP, but I can't seem to get him to hold his head low at a lope. I know he can do it, because at a walk he has a good, very slightly above level headset but he seems to lose that at a trot or lope. (when he's unusually tired or relaxed, he holds it low at the trot but almost never at the lope.)
What are some things I can do to lower his headset at the trot/lope without it looking unnatural? I have thought it might just be his natural head carriage, but looking at videos of his sire and dam, I really don't think that's the case! Plus on the lunge line, he has a nice level headset at all gaits.
