My horse puts his head down when he is in canter. Then he becomes difficult to turn. I don't know what I do to cause this and yes I think it's caused by me because when others ride him he doesn't do this. I try to sit back on my bum, open my thighs so Im not blocking his forward. I try to keep contact with the outside rein. I look to his outside ear so I'm not unwittingly turning him to the inside when trying to go straight. To turn I keep my inside leg at the girth but what do I do with my outside leg?? I try to keep my pelvis going with him so I'm not blocking. Can anyone else tell me what to do or not to do. Feeling frustrated. I just want to canter in a circle. Thank you.
