Also when I ride him he trips constantly especially when I ask him to do something he doesn't want to do. When I am in the round pen riding he tries to walk over to the gate and stand there so he can go to the barn. When he tries to go in the middle and go to the gate and I correct him is normally when he trips. I have tried disciplining him when he trips but he hate tripping and it make him mad to trip so that just makes it worse.
We have made a good bit of progress since I got him, he is better at ground work, he stands still better at the crossties, he actually seems to enjoy being brushed, and he is less pushy. I just can't get him too stop trying to go to the gate and quit tripping. What are some ways to fix these problems and why do you think he is slightly lame every once in a while? Thanks!!!!
