When your dog acts aggressively toward strangers you have to put a sign up on your fence so visitors don't come waltzing into your yard and get their butts bit.
And it's still fun to put up a "beware of dog" sign when your dog is a big ol' softie who'd rather lick people to death than bite them, if only so your visitors can have a good laugh.
But there are lots of dogs out there who need to be identified as dangerous even though they only pose a threat to your ankles, because little dogs are often feistier than their larger relatives.
But the most dangerous and sign-worthy pets on the block aren't dogs- they're the cats who are so hardcore their owners felt a "beware of dog" sign was more appropriate!
