I usually use a Ruger 22/45 at home for protection against snakes, stray dogs, chicken killing critters, etc. I always let my chihuahua out when I get home and carry my 22/45 when we walk together but the other day when I arrived there was a pit bull and a rottweiler at the top of my driveway. HMMM not cool. My chihuahua will attack larger dogs and has on more than one occasion. I got out my Mossberg .22 rifle and loaded it w/ stingers........then dropped my Taurus 9mm loaded w/ plus p's in my front pocket. I guess sometimes a .22 isn't enough.
