Do you consider your pet part of the family? Meet Rex, a Belgian Malinois who was rescued from a shelter by Erin Switzer, who was being featured on the cover of the popular video game "Call of Duty".  The company needed a dog to play a key role in the game and wanted a realistic dog character that players could relate to and form a bond with. Just like his predecessor before him, Rex became a household name in the gaming industry over night and has been featured in many ads, telivision and film.  Join Christopher and Jamie in this unique episode where they actually have the first pet in studio joining them.
