I'll be gone from home for the next week, but when I get back I am going to set up trail cams again down the lane to see who is visiting while we are gone. I will deal with trespassers in a proper manner (utilizing local law enforcement) and if the dogs keep coming back, I will try every avenue possible to encourage them to stay away. When I have exhausted some ideas I received from friends, then I will attempt to live trap them.
