Nasty would be accurate. I can't think of another predator that does as much damage as coyotes to all types of other critters, domestic or wild. I have lived on both sides of the state and seem them in operation in both places. A slightly injured "educated" coyote will still go breed and make a bunch more coyotes that need educating. That educated dog will just learn to stay away from your place and simply move onto another. I would much rather kill one outright than shoot his tail off or put a hole in his ear.
