Besides firearms and a monitored alarm system, we keep pepper spray and a 500k stun gun in the bedroom. There is also Moose, our 3 y/o 80 pound black Lab. He's really just a VERY large, lovable puppy who wouldn't hurt anyone or anything unless he accidentally stepped on it. However, he's well over 5 feet tall when he stands on his hind legs, sounds like a passing freight train when he barks and he'll scare the living daylights out of someone who's not expecting to see him. He also makes an OUTSTANDING burglar alarm! Imagine sticking your head through a window at night or jumping the fence into our yard and seeing just a glowing pair of eyes on a head the size of a bowling ball looking back at you from an arms length away.
