I live in the country and off the main road 1/4 mile. I have dogs and a fenced yard. The dogs bark at strangers. The dogs bark at other animals. I know the difference in the barks it is very noticeable. I have a couple of motion lights in the yard and a few large "guard" lights out around the out buildings on switches. I keep the lights off as I like it very dark for sleeping. 2am and the dogs are barking the "stranger bark". Do you just turn on the light and hope the trespasser leaves? I could easily walk out the front door ( the dogs would stop barking and come around front) but I would be out of sight to the back of the place and sneak around with a weapon and have the wife flip on the lights and try and catch the trespassers?
