It's funny, but "dignity" isn't the first word that came to mind when I viewed these pics (only two from a list of thirty-one "pet Halloween costume ideas!").
I understand loving your pets. They're amazing companions, and most of them are more loyal, good-natured, and--dare I say it?--intelligent than humans. But must we anthropomorphize the poor beasts? Can't we show our love and appreciation without subjecting them to the indignity of silly costumes?
