Anything I can do to stop it in a nice way?
Or try with him?
History: Ex racehorse, just started schooling work, makes alot of faces all the time with his tounge - bridle or no bridle.....all checks have been done so I know he's not in pain but happens more when he is a little stressed (i.e new place to ride) .
I am debating going bitless not just because of this issue... but have no idea....
