And even if you set all concerns for the well being of the horse aside, how about simple self preservation for the HUMAN? These horses are dangerous without meaning to be. When I first encountered HYPP I had no clue it even existed, let alone how to recognize the signs of an attack. When I went to work at the barn the trainer didn't explain what to look for and I ended up having 2 horses go down ON TOP of me before someone explained about these things. These things were HUGE and let me tell you, not a horse I wanted to be under while it thrashed. They can't get up off you if they even knew you were there.
Stress aggravates the condition, so how well do you think you'll do if the horse goes down in the ring in front of the judges? And God Forbid, what if the horse went down ON TOP of a judge? Or the Handler?
It makes no sense to me at all. You cause untold suffering for the horse, increase the likelihood of a human being injured and for WHAT? Good Grief!
