Bucking at the canter
This is the newest bump in the road with kids. I ask him for the canter, and he does his signature four foot leap/ buck. It’s a huge pain on the ass , mostly because it shatters my self confidence and then I am back at square one – which is probably why he does it. It gets him out of the task at hand. He pulled it again today but I had had my wheaties so instead of letting him get away with it I just made him work thru it and work that much harder. After getting ten strides of a nice canter finally we called of a day.
Baby steps .

My guess is the less he gets aways with it the sooner this behavior will disappear.
