For a few months now I have been riding a 12yr old 15.3hh Mustang mare (who has some noticeable draft in her). I would not consider her green, she is a very intelligent horse, but so much so that she likes to test her riders.
This is why my riding instructor put me on her...
She had a lot of training when she was younger but had not been ridden consistently since then because of her sheer power. She is VERY forward and always wants to go, go, go. She also knows when she has someone on her back that she can take advantage of, and she will do just that.
Since I have been riding her, we have made a lot of progress at slowing her paces down. She has her bad days where she just does not want to listen, but then she has her good days when we can actually do some crossrails.
She is normally pretty good going to the left at w/t/c, but her biggest issue is going to the right at a canter. She is constantly trying to run me into the walls around the corners. Even when I try to take the corner early, she just completely ignores me. I don't think she is trying to be mean, or hurt me in any way because she has never actually ran me into the wall... she just gets really close. The farrier and vet have both looked at her, and agree she does not have any lameness issues.
Any advice about how I can stop this bad habit?
