I didn't want to make a new topic, so I ask it here.
I started lunging a 4 y.o. Standardbred mare. She is pretty good already, but only when she has to run to the left, if I change the direction, she runs couple of steps & then turns to stop, steares at me & tries to back up. I ask her to start moving again & she starts to run to the left again!
I tryied to shorten the lunge, but she still does it. And I can't shorten it always, she has to learn running to the right direction.
