I' m going to risk pissing people off, but. I don't agree with hunting bears with dogs. It is illeagal in most states. Now that said, I think you are all missing the point.I f the wolves are killing domestic animals and so quickly. I would be in fear of them traveling in to populated areas , human children would have now defence to life though this packs attacks.
We have several packs in our area they have gotten so big and fearless that they are killing each other, we have had cattle and other hoofed animals. If they do start on dogs the game department will have to do some more changes to wolf management.
I aslo agree he was stupid in returning to the same area after the first dog, but really after 2 I think he should have his head examaiined.
