Found it. I was brush cutting CRP and a young coyote ran out into a pasture. Willard thought that might be easy pickin. He was in hot pursuit. The coyote suddenly stopped and laid down on it's back. Willard thought this was a gift from the "Hunting God's". He piled on. And, he instantly jumped back off and ran to the tractor as fast as he could go. By that time I finally got the phone camera going.
