One in a minion.
A proper henchdog should always look cute, yellow and presentable. So always make sure your little minion is wearing the Despicable Me Minion Printed Pet Costume. Specially useful when you are trying to take over the world and international news cameras are everywhere. Everybody knows there is nothing more embarrassing than a minion that looks like a regular dog. After all a properly dressed villain needs a properly dressed adorable minion henchdog.
