Dovie gave all the horses baths today. Something set Diego off half way through the bath. He freaked and then settled down. I wasn't there, so you'll have to ask Dovie for the details.
Me: It seems it was dragging the hose behind him which caused the issue. He’s fine with the hose, I have to drag it in and out of his corral to fill up his water trough, so it’s a common enough occurrence. He’ll stand there while it goes under or in front of him, so I think this was a “something’s behind me” issue rather than a hose issue.
We just got back from a moonlight ride. We did the same ride we did three weeks ago. Every time I ride him, he starts out skittish and then gets better as the ride goes on. Tonight was no exception. He was looking around a lot, but didn't do anything stupid or dangerous. We trotted about 20%. That gave me a chance to practice trot-to-walk transitions and I had good success on the trail. I closed the gate from his back. He didn't seem to understand what I wanted, but the slamming gate didn't scare him.
I'm seeing the fear of monsters behind him that you told me about. I'm going to try to desensitize him to various monsters tomorrow (with nobody on him). He's really fun!
