My horses cantering problem?

Question

My horse is a 4 year old paint quarter horse. He is a very calm horse at the walk and trot. He sets his head beautifully at the walk and trot. Then i go to canter him. he sets his head good but he pins his ears back as far as he can and looks very mean. i just got him to stop bucking at the canter but cant get him to stop this.

Answer 1

It sounds like he may be uncomfortable at the canter (perhaps saddle doesn't fit properly). If you have a round pen, try cantering him with sidereins in it...or maybe try lunging him. See if he has the same problem without a rider.
