When I take her on a "trail ride" (we just hack around a hilly hay field), she gets scared when she can't see the barn or other horses. She freezes and her heart starts to beat SO fast- I can feel it moving my legs. Then she starts trying to run back to the barn. I try to stop her and make her go forwards, but then she rears and spins at the same time. Last time she did this was a week ago and I just got off and walked her on the path back to the barn.
I have tried taking her out with 3 other horses but she threw a fit about being in back- she wanted to be in front the whole time. I took her out with just one other horse, but she still got so scared and had to go back.
What should I do? I really want to do eventing with her, so she is going to have to be away from the barn and by herself. I have thought about just taking her for a walk on a lead rope around the field, but I'm afraid she will pull the rope out of my hands and run back to the barn. I have asked my trainer about lunging her out there, but she doesn't want the ground to get messed up as we only haclk around the outer edge of the field.
