This session lasted about 25 minutes. To start, I moved the trailer forward from its usual spot about 40 feet. The test is to see if Atty will load in a new spot, showing that he has generalized the behavior, of if he needed to be retrained or shaped to load here.
He got to have some grass first then he loaded well, I put up the butt bar and closed the back doors, and I went off to feed the other horses.
I came back and treated him and opened the one back door, went up front and clicked and treated and asked him to target three times. Then I went back to unhook the butt bar. He stayed put and I went up front to click, treat, and target some more. Then I went back and cued him to back off the trailer. I clicked and treated and took him to eat some grass.
I asked him to load again just to see if he would and so he could finish his breakfast. He did load again. While he was eating his breakfast, I walked around a lot, showing up at his door and at the other side door for variety.
Then when I went to unhook the butt bar for the final off load, he backed into it. So I kept it hooked and went up front. Then I went back to try again. He stood still this time for me to unhook the butt bar. But I knew he wouldn’t wait for me to come up front to click and treat, so I cued him to back off and CT’d that.
I could, I suppose, have let him come off without the cue, then reloaded him and tried again, but I chose not to.
