BIG DOG ! GOOD JOB, well done
A 22 pistol might make them easier to get out of that trap, Doc

Urinating on thier carcass and leaving them right there, sends a message to both red foxes and coyotes, you are speaking to them in a language they understand, and marking your territory as they do, they understand. That's helped big time many years ago. It would make trapping or baiting particularly hellish I think.
