Getting back to the original discussion of topic, he first layed down with her on him. I was not there, but this is what I have been told. She immediately popped him with her crop and he got right back up. A few minutes later, while being led, layed down again. He did not try to roll, did not paw at his belly, did not stretch legs out, simply layed down as if to rest. The second time the neighbor/BO was there and "persuaded" him to get up. Neighbor (very experienced horseman) said he was just "being lazy and punking her."
Daughter and I had a talk about asserting herself with the horses and establishing herself as dominant. We will be working on that tommorow.
