I have a 4 year old Appendix QH, who has been ridden a handful of times. I have ridden her a couple times with other horses and she does great, but alone she pitches a fit and walks really fast backwards toward home.
Today I rode her, and made some good progress by either turning her in small circles while still mounted or getting off and driving her in circles each time she'd do the backing thing. Once she went away from home willingly (ish) I turned around and headed back, but stopped periodically and headed out again, and repeated the battle on a smaller scale, until finally she didn't fight me, and after that time, I turned her around and we came home.
I think she got it- but I'm wondering if anyone has any ideas or tips that have worked for you?
