If you want to survive a home invasion, get a large dog. The dog will stay alive and fighting/distracting for those 4+ seconds required for you to arm-up.
Simple beats being paranoid...some people try to survive home invasions by taking baths with their revolver next to the tub because baths are quieter to take than showers.
Bah.
Get a dog and take all of the showers that you want.
lmao.
Good point you bring up, I raised this question on another forum. Home alarm with motion detectors on dogs in your room, or home alarm doors only, dogs free reign in the house.
