i have a small dog that yaps at everything outside but a big dog that only barks when there's a person or a car or something coming up to the house, it can be annoying but i've never tried to stop the big one from barking, because although annoying, it's worth the peace of mind that there's no way someone is going to sneak in here or something without me knowing. im not exactly paranoid but im not stupid enough to trust a built-in security system either.
