I shot a Fox last year at 15 yards with my bow, after the shot the Fox fell to his back and had his legs straight up in the air quivering, i thought to myself he is done, so i DON'T knock another arrow, after a couple of minutes my buddy gives a WooHoo out and all of the sudden the Fox lifts his head up, and I still DON'T knock another arrow, he then lays his head back down slowly and I think he's done, so i'm just standing there waiting for about 3 more minutes and this dang Fox gets up (NOW I'm TRYING to knock an arrow) and runs off we look for him for 2 hours and never find him.
