I'm having a hard time keeping my horse's gaits under control. He wants to trot all the time and if I don't let him, he get's mad and pulls on the bit. I've started riding him outside of the pasture and he always tries to drag me down to the road. I've done a lot of half halts and I talk to him to try and calm him but I can literally him tense and wanting to run. His previous owner did a lot of galloping and fast work with him and he seems to thrive on that. Unfortunately I have very limited areas to ride because we still have a couple of feet of snow on the ground. I'd love to lunge him but I don't have a place to do it, and he's never been trained to lunge before, so I'd like to get a trainer to help me.
Does anyone have any ideas on how to control his speed and keep him relaxed? If he ever did seriously bolt which would be the best way to stop him? I've heard that turning him in a tight circle works. I've also read in a book that the best way to discourage bolting is to make him speed up and when he tries to slow down, speed him up again. Apparently it will discourage him.
