Meet Bo, the Obamas' new dog.

After months of anticipation, a 6-month-old Portuguese Water Dog named Bo is now calling the White House home.

First, the name. According to The Washington Post, which published confirmation of the White House dog news Sunday, Malia, 10, and Sasha, 7, chose the name because their cousins have a cat named Bo and because Mrs. Obama's father was nicknamed Diddley, as in Bo Diddley. The dog is a gift from Sen. Ted Kennedy, who owns three dogs of the same breed, known for high spirits and said to be a good fit for kids with allergies (such as Malia). Kennedy had been lobbying the Obamas to get a Portuguese Water Dog  for months.

And look at how cute he is!
