These dog masks are just the thing if you're in the mood to leave a little surprise in someone's house slipper. Be a man's best friend (or worst nightmare) this Halloween with one of these puppies. Looks extra spooky when uneasily mixed with casual human clothes. Word on the street is that Buck the German Shepherd (shown below) has blown so many people's minds that it's backordered almost until Halloween. See more masks here. Via Dangerous Minds
