All my friends are sharing pics of their kids dressed up for Halloween, and yeah, they're cute, but you will never convince me that a kid in a costume is cuter than a dog in one.
Never.
Of course, if your doggo is unhappy about being dressed up, then don't fight them for the photo-op, but if they don't mind or — gasp! — even like being clothed, then you better be sharing that adorableness on social media. It's the law.
