When I was young and on the farm, we kept 2 pit bulls and a collie. We weren’t too worried about unexpected company of any kind.
We farmed until 01. Always had a dog, not only for security but to alert us if livestock had gotten out, until we quit farming and moved to a small 19 acre farm a few miles away. We were in view of the neighboring farmer’s barnyard, less than a 1/4 mile away, whose dog would bark in our direction whenever something moved around, day or night (except for the horses).
Here in rural TN our closest neighbors are about an 1/8 mile away. Plenty of dogs, guns, and signs warning strangers....
