I have a quick question. Dessi has been coming along training wise, and she is a very intelligent horse, one thing that I have noticed is that when asking her to back up (on the ground) she is so dang slugish! And I am not exaggerating it's -think- bring one foot back, -think- bring the other foot back. What can I do to make her backing up a little faster? I realize that there is a limit about how fast a horse can back up, but we have an arthritic 9 year old who backs up five times faster than Dessi.
