Your dog's senses are several thousand times more potent than your own senses. Donna Pauley of the Kanawha County Animal Shelter told me that criminals are preemptively neutralizing out dogs prior to committing various crimes. You with an AK-47 are more formidable than any dog imaginable. The dog is the radar station, you are the flak gun.
Bring your dog in about 9 p.m. and put them inside a plastic dog crate. This has multiple advantages. A. 'Denning' is a natural instinct of dogs.

It allows you to bring a large dog inside at night without the hassles a free-roaming dog can bring. Why shouldn't your enemies have no advantages over you at all?
