My friend's horse doesn't like going into a lope in one direction and will buck if she makes him. The buck today was a small one she could barely feel but last time was a heels in the air real buck although he didn't get her off. He's done it before as well but has never gotten her off.
He's been checked physically a few times by a chiro and a massage therapist so there's no physical reason that she can find for him to do it. He's 8 years old and was broke as a young horse and then left for quite a while and only ridden sporadically. He had some fear issues but my friend has brought him a long way and he's very laid back now.
Here's my question. What would you do to a horse that did that? A couple of people who are good horse people have said to get off and punish him and then longe him until he's tired and then get back on. Another horse person as well as myself feel that seh should stay on and just do some disengaging his hind and small circles and then ask for it again. We feel that getting off and dealing with him is long past the point where he's going to associate it with the buck.
Any thoughts? Thank you!
