Anyway, so I put some hours on him anyway, saddled and rode him for the first time. He now has about 6 rides on him and I've decided he's good enough to go to someone with more time and patients than I.
I found someone interested in him and they want to come get him tomorrow, but I've never loaded him. The people I got him from said they loaded him just fine. I don't have a horse trailer to practice or test on, and he can be very difficult when he gets nervous (which is a lot).
When he gets nervous, he bolts away as hard as he can, which for a 650lb burro is pretty hard. Even my farrier got dragged.
So, for anyone with experience with a nervous donkey, what can I do? I want to avoid that dreaded bolt any way possible, because he's a PIA to catch when he's loose.
I use clicker training and he responds well to it.
