He had a noticeable tendency to take flight when the trainer started him. I have spent a lot of time getting his reaction to be less severe.
Basically I strived to get him to understand, it is okay to be scared, but you don't have to run. I got the trainer to understand
what I was working at teaching him when I took him up for a refresher. So many horses get scolded, and are
made to go in circles, basically as punishment for spooking. I prefer my horse be aware of his surroundings, and bring things to my attention, and not be worrying about what I'm going to do to him if he gets scared.
If a little kid is scared of a dark room, a person shouldn't shove them in there and close the door. I figured the same for my horse.
