Bo

Meet the new first dog.

Bo is a six-month-old Portuguese water dog given to Malia and Sasha Obama as a gift by Sen. Edward M. Kennedy of Massachusetts. The black-furred fellow, who has white patches on his chest and chin — plus white paws — is scheduled to move in Tuesday.

The Obamas had hoped to get a rescue dog, and in a way they have: Bo had been living with another family, but it wasn't a good fit, so the Kennedys gave him to the Obamas, The Washington Post  reports. He was originally named Charlie, but the Obamas are renaming him.

The Post had planned to introduce the pup to the world by running an official White House photo on its Sunday morning front page, but a mysterious website called FirstDogCharlie  published a picture Saturday morning of a pup that looked just like the one in the official photo. The White House calls the photo on the site "bogus."

The Post also reported that the dog charmed the girls in a surprise get-acquainted session with the family known internally as "The Meeting." Bo was well-behaved and obedient throughout the meeting, sitting when the girls sat, standing when they stood, and maintaining his toilet training.

"We couldn't be happier to see the joy that Bo is bringing to Malia and Sasha," the Kennedys said. "We love our Portuguese water dogs and know that the girls — and their parents — will love theirs, too."

The Obamas are also making a donation to the D.C. Humane Society.
