Jennifer Garner and Ben Affleck took their German Shepherd out for a walk in LA yesterday. The pup is a new addition to the Garner-Affleck family, who already have another dog named Martha Stewart. Jennifer recently chatted about how the canines get along at home on The Tonight Show and she also touched on the next family member due in the Spring. Jennifer shared that her daughters have already started thinking of names that are "definitely Disney" and that the whole clan is excited for the baby's arrival. Ben and his girls will have something else to celebrate first though, if the New England Patriots win the Super Bowl. They'll be playing the New York Giants on Feb. 5, which is sure to be a big day in the Tom Brady-loving Garner-Affleck household.
