Taking pictures of people? A snap. Pets? Not so much. On tonight’s Extra, Mario Lopez gives us an inside look at Rover, the new book from photographer Andrew Grant, who filled its pages with rescue dogs to bring attention to the plight of animals being given up in this recession. It wasn’t easy rounding up the furry subjects and getting them to pose, but all of Grant’s hard work is paying off: A portion of proceeds from the sale of the book are going to pet charities.
Meanwhile, Mario is still looking for a puppy to call his own. Whoever he chooses is going to be one photographed pooch!
Watch Extra tonight at 7 p.m. ET (check local listings) and check back later for a Mario Great Puppy Hunt Poll on PEOPLEPets.com!
