Back in the mid-eighties, there was a pack living under a rural abandoned house near my hometown. Must have been 30 of them. From all accounts a lot of inbreeding. These dogs would come out from under the house and chase, snap and growl at every vehicle that drove by. I can't imagine what they would have done to someone out for a walk or a bike ride.
One day a farmer tied gunny sacks to the wheels of his truck and drove by slow. The dogs would grab a gunny sack and get their necks snapped. I can't remember how many he killed doing that but I believe the Sherriff's office took care of the rest.
A wild dog is a dangerous dog and needs to be eliminated.
