WASHINGTON - APRIL 14: U.S. President Barack Obama (2nd L), first lady Michelle Obama (L) and his daughters, Sasha and Malia (R), introduce their new dog, a Portuguese water dog named Bo, to the White House press corps on the South Lawn of the White House April 14, 2009 in Washington, DC. The six-month-old puppy is a gift from Sen. Edward M. Kennedy (D-MA) who owns several Portuguese water dogs himself. This breed of dog is considered a good pet for children who have allergies, as Malia does.
