I have had my horse for a year now. When I first began riding her, she did not move forward. Rather, she will move backward. I have been unable to ride her since November, due to an injury. Now that I'm back on my horse, I need to get this habit fixed. I know that she did this with her previous owner as well. The only way to get her to move forward is to use a stick (I trail ride) but I'd rather not.
What are steps I can take to fix this problem?
