Well, today when I rode Thumper, he did a little buck at the canter. I was debating whether to continue to ask him to canter, or to relent a bit. And that got me to thinking, are there any ways/tricks to decide whether the horse is telling you that he's uncomfortable, or if he's just trying to get out of working? I don't want to go back to a walk if Thumper is just trying to get out of working, because then he'll know that when he throws a buck in there he won't have to work. BUT I don't want to continue to ask him to canter if he's uncomfortable... So are there any ways to tell, or do you just have to go with your gut feeling, knowing the horse? Thanks to anyone who can clear this up for me :).
