It's a popular theory that pets and their owners look alike, so why not make it true, at least for a night? Dress your dog as you. The easy way out is to get matching costumes for you and your pup, but it's much funnier to truly make your dog into a Mini Me. Alter some old work clothes and suit up Fido for a day at the office, or play up one of your defining characteristics on your dog -- glasses, beard, long hair, whatever -- to make sure people know your pooch is supposed to be you. If you pull it off, you'll take the cake at any Halloween parade.
