Desensitization to the Ring with a horse that needs extra time

so this is Miracles introduction to the ring with streamers or as he would think of it the Ring of Doom. he did not have a very good reaction to the ring as opposed to the other horses that you've seen. he was very reactive and didn't get to the point on our first session where we could actually leave him through it. sissy is on a tune-up we are doing as much desensitization with him as possible and we are going to feed him next to streamers and things that move. As well as tie up other things that move around him while he is standing tied all in order for him to get used to lots of scary stuff.
