It it that rude narcissists know their annoying yapping dogs in their backyards are driving everyone else batshit and they derive secret pleasure from this modicum of power? Or is it that small dog owners are more likely to be truly stupid and they really can't equate the yapping with, say, someone screaming, "Hey!". "Hey!". "Hey!". in a high pitched voice over and over for hours?
I'm inclined to think it's the first, but I've noticed most small dog owners seem to stay inside watching TV, so maybe it is the latter.
