George H.W. Bush

George H.W. and Barbara Bush’s English springer spaniel Millie made quite a name for herself in the White House. She appeared on “The Simpsons” and “wrote” New York Times bestseller “Millie’s Book: As Dictated to Barbara Bush.” She is the mother of two other White House pets, Bush’s dog Ranger, who they kept out of the litter she had at the White House, and Spot, who was given to George W. Bush and ultimately returned to Washington with him years later.
