Thanks!!!! I have realized that rears are preventable. I am so glad you said that about the smacking though because I do not want a bucking problem to arise. Before he does completely stop what should I do? I have gotten him to the point where reassuring him through talking and light pressure get him to keep moving when he feels reluctant but when he gets closer to the barn he will stop entirely. Won't move any direction, won't go in circles and if he does he will do a circle and then break it to walk to the barn or he will stop. Do I wait until he absolutely refuses or can I do something when I feel he is about to?
You can do a couple of things. First, ditto what another poster said about the rearing, quickest way out of that is to keep him moving forward at a working pace. That said, when he even thinks of slowing down, you tighten your leg and ask him to move out again. If he doesn't, I wear spurs and carry a crop, and I tap with a spur as more of a "Tell" him to move forward. If he still won't, I let him have it with spurs and crop, on his ribs, and I keep at it til he moves on. Not sissy gigs or taps, he gets both heels hard and whacks that get progressively harder. You can end up in a real fight here, so I'd recommend a trainer.
When he tries to break the circle, grab the inside rein and pull his head clear to your knee if you have to, to keep him bent and circling, and apply your legs as hard as necessary to keep him moving. Get progressively tougher until he gives you what you want. Again, you can end up in a Hayell of a fight at this point, and you could end up getting hurt if it gets really ugly, so a trainer would be your best bet.
Since you say you're a new rider, I'd really suggest taking the horse to a trainer to have those nasty little habits taken out of him, if you get into a fight with him, you could get hurt. Once the trainer re-educates him, you can ride safely and learn how to fix any issues as they crop up, under the trainer's supervision. MUCH SAFER way to go than what you're trying right now.
Notice I said, when you feel HE"S GOING TO TRY to slow down, stop or break out of the circle, not wait til he does it. If you make him work for thinking about it, pretty soon he'll quit thinking dirty thoughts and just start listening to you.
I don't care if the trainer is your boyfriend's uncle, a good trainer is a good trainer, and they can keep you safe. I've been riding for over 40 years and I can stick just about anything they want to throw at me, and I use a trainer to get the horse going where I want it and to work with me on various things. I don't bounce so good anymore, so I pay the trainer to take my lumps.
