I tried to join up for the 1st time with my 2 year old QH mare, Bella. I drove her around my round pen with her lead rope. She kept her ear locked on me the whole time but didn't lower her head or chew air. Everytime I stopped her she would turn her but to me instead of coming up to me. After a while of driving her around the pen she stopped. I did everything I could to get her to move, she still wouldn't. Did I do something wrong?? I need help urgently beacuse my parents said that they would sell her if I didn't get her trained this summer.
