Eventually I get him to trot but he's rushing and bracing against me a bit. So I thought i'd get home and work him a little more, a couple of circles etc to get him listening to me and relaxed. So I take him out back in a paddock, ride him around, he was nice and foward, maybe a little rushed at times but light as a feather. I look down and he's under the bit
He wasnt ducking under the contact, just keeping his head behind the vertical. So I attempt to fix this by pushing him up into the bridle. Nope, didnt work. He'd either bring it up for a second then back down again, or use my leg aids as an excuse to rush off, then when i'd half halt duck under again.
Then I tried doing lots of transitions, that wasnt very successful either. Eventually I got a bit frustrated and decided it was time to get off
See, even though he was rushing, he was tired, but he's the type that will just keep going untill they drop.
So I think the tiredness definitely did contribute to him going under the bit, but I need a solution, especially since at shows he needs a really good work down otherwise we have a nightmare on our hands.
Sorry if that was kinda long, and I hope I explained it well. So, help?
