My horse is 13 years old, very sweet and is great at everything we ask of him...except when we canter. When cantering free lunging, or on lunge line with saddle he doesn't buck. When we ride only to the left lead he bucks, the other lead he does not, normally, except the other day he was bucking, squeling, and at one point running side ways, both ways. I ask from the trot, don't surprise him, and I am not kicking him in the sides like a barbarion either! We do keep short reins when asking because he has history. 2 owners before me (if that makes sense) they had to get rid of him because he was bucking during jump courses, so he has history of bucking when asked to canter left lead. We don't know what to do, and sometimes I ask for canter and he is fine and goes into it. Even on his good lead he normally squels before cantering. The vet has come and says he is fine, just a bad boy, but I would like to think he is a good boy, the chiropractor has come but, it doesn't seem to really help. We currently do stretching before riding too.
Thanks for anybodys help!
