Meet Bo, America's First Dog

Arguably, it was more talked about than the top Treasury post, more debated than the Department of Homeland Security: Who would be America's first pooch?

But now we have an answer: It's Bo, a 6-month-old Portuguese water dog the Obamas are reportedly adopting, said to be a gift from the don of Portuguese water dog lovers, Sen. Ted Kennedy, D-Mass.

The president's daughters, Malia, 10, and Sasha, 7, have named the black-and-white puppy Bo, according to The Washington Post, because their cousins have a cat named Bo and first lady Michelle Obama's father was nicknamed Diddley. Like Bo Diddley.

It was, for a while, the best-kept secret in Washington. Secret meetings were held on the subject, and a clandestine rendezvous was arranged just weeks ago between Bo and the Obama girls.

Bo is expected to arrive Tuesday.
