A big man requires a tiny dog, so that things average out. It's Jorge Garcia from the nonsensical sci-fi series Lost, with his chihuahua-dachsy mix Nunu, in the above photos. He's holding a different, fawn chihuahua in the bottom-most photo.
Terrible sad update. At the start of June, 2010, Nunu was struck by an automobile while crossing the street. Jorge ran to snatch her up, but she died in his arms. "She was the greatest," said Jorge, who purchased a burial plot for Nunu in the Pet Garden at Valley of the Temples in Kaneohe, and will obtain for her a bronze plaque. "She hated the water," said Jorge, "so I didn't want to scatter her ashes at sea."
