Also, backing up is getting to be frustrating. First we worked on going around the arena and me over-exaggerating my seat aids (leaning back and really pushing my seat down), and getting her to stop. After that, we added backing up. She stops crooked and backs crooked too. She also backs very, very, slowly, and with a lot of resistance. It's hit and miss - sometimes she'll back with her back round and in a straight line, and other times she'll back with her nose in the air and feet going everywhere.
