My pony naps towards the gate when i am competing, how do i stop her from doing this?

I wouldn't ever take her through the gate as one poster mentioned (my opinion), but what I would do is leave the gate open and tempt her with it. The moment she even leans towards the gate take her into small tight circles, and work her pretty good, make her give you her face and trot and really make her form and work for it. Make her do it both ways a few times, and then take her back to work. Keep repeating this till she realizes that when she leans towards the gate, she will have to work. Also make sure that you don't subconstiously think or look at the gate to send her mixed signals (not saying you do this, but sometimes people do things their not aware of). Since you know she will do this, people will be afraid their horse will do it again, unfortunately causing the horse to do it again. This isn't too bad of an issue to correct. If she doesn't do it at home, but only at shows, pick a few open schooling shows, and do just that, school. Don't worry about placing, worry about correcting the gate issue so when a bigger and better show comes along, she is not going towards the gate.
