I don't know . . . . coyotes can be nearly beyond belief in terms of will to live. I shot one once with a .300 Winchester while elk hunting. He collapsed in a snowy meadow - didn't even flinch. Figured I would keep hunting and pick him up on the way back to camp. When I got back to the meadow, there were his tracks in the snow - where he had gotten up and walked off. In the snow, I found chunks of rib bones and all kinds of bright red blood where the bullet had blown through him. Never found him.
