Hate to hear that about the red fox. Unfortunately that is part of trapping. If a person traps, things like that are gonna happen. I have caught a few domestic dogs before. Most have came out pretty well but some not so well. A person is gonna catch a non target animal every once in a while, those things happen. I bet I caught at least 6 rabbits this year in conis and leg hold traps and most were dead tore up by yotes.
