I lunged Montana over a small vertical yesterday. It was between 10-12". I only asked him to jump over it 2-4 times. The first few times he went over it, he went up to it trotting and when he landed he would break into a canter and then proceed to buck, jump in the air and act like a doof.
When he did finally jump it and land in a canter and didn't do any doofy stuff, I rewarded him and ended the lesson.
Before hand I did warm him up at the walk/trot in both directions. Going to the right he did act up a tiny bit,but I immediately corrected him. (It was also the first warm day in a while so that could have played into it)
Anyway, the point of this post was, should I be concerned that he acted out like he did when he went over a jump?
I do know he was previously jumped and I was hoping to jump him in the spring/summer, but obviously this bucking this is going to put a slight damper on that.
Any advice would be appreciated!
