Rubies Costume Co. Inc Monsters, Inc. Mike Dog Costume Green/Blue/

Scaring Is Caring
Big or small, fluffy or short-haired, each dog likes to feel as though he or she is their owner's main protector. They'll happily growl and bark to let the mailman or the neighborhood squirrel know that they won't be able to try any funny business on this pup's watch! But despite the show of toughness, they'll give you plenty of puppy kisses to let you know that they'll always be your best friend. They are as loyal to you as Mike Wazowski is to his best friend Sulley and their new friend Boo.
