Loading Catfish, my horse, into my new trailer was fine, but 
the problem occurred when I went to unload.  I opened the back 
door forgetting that Catfish had not been trained to stand until 
I cued him to walk back. He saw the door behind him open out 
and started stepping back. His lead was tied, but the slack was 
enough to allow him to get into his step down before it went 
tight. I could see this as it was happening, but I was out of position 
to do anything to stop it. I sucked in my breath and watched. 
God was on this fools side that day. The lead went tight and then 
broke allowing Catfish to finish his step down. I was there before 
he before his other back leg touched the ground. We walked on 
out and I lead him out into the field. We walked around for several 
minutes while I recovered from the scare.
Regards,
Scott
