I know you said it is a rural area, but isn't there animal control in the area? A pack of dogs intent on attacking people are a danger to the public. The state police are useally you next option. Now,if they won't do anything, then I say protect yourself.

Some of us on here have said. He posted it now the cops will know. OP has said the local PD has already told him to protect himself. They know his next step. Though I think a mace spray made for animals would be a good next step. Don't use a pepper or mace made for people. Not as affective or long enough spray. But do what you have to do to protect yourself.

And for all those people who don't agree with his actions, you've never seen a pack of dogs attack AS a pack. Dog in a pack whip each other into a frenzy. A lot like people. But dogs can't be reasoned with. They are dangerous.
