found fresh fox tracks today and wanted to try snaring. my question is: do snares necessarily kill what is caught in them? I am asking because there are a few dogs in the area and I DONT want to catch one of them. I know setting the snare with a smaller loop (8 or 9 inches) and only 8 or so inches off the ground will help, but i would hate to have some kids dog get caught. Thanks for the help.
