Ok so I have a 6 yr old OTTB I just started to work with him and he's a great horse just very green.. The problem I'm having is he bows out and will not stay on the rail when I'm riding him. I try using my inside rein and leg to push him over but he just doesn't understand. He will turn his head towards the rail but he keeps his body bowed out and won't move over. I'm going to start lessons with him in feb, but I wanted some advice in the mean time.
So how do I teach him to move off of pressure?
Also he's really mouthy with the bit. He's got about a 1/4 inch on each side of his mouth so it fits and it's a french link so it shouldn't be pinching. Could it be hurting him??
