Okay, I know this makes me sound like a total imbecile for asking but when I am riding in the arena my horse turns easily left and right when I ask him... BUT when I am out on a hack (or anything else outside of the arena) when he does not want to do anything... e.g; walk further down the road or if he is by himself, he stops and he will not turn right, he opens his mouth to evade the bit and wont even move even when I ask him with stronger aids. I have tried to ride him with a flash band but he still does not listen. On the other hand I can turn him left but he still will not move forward.
I would really appreciate the help (:
P.S He moves easier on the left side
