The little guy is a 6-month-old Portuguese water dog given to the Obama girls as a gift by that Portuguese water dog-lovin’ senator himself, Edward M. Kennedy of Massachusetts. The girls named it Bo — and let it be noted that you learned that here first. Malia and Sasha chose the name, because their cousins have a cat named Bo and because first lady Michelle Obama’s father was nicknamed Diddley, a source said. (Get it? Bo . . . Diddley?)

Bo’s a handsome little guy. Well suited for formal occasions at the White House, he’s got tuxedo-black fur, with a white chest, white paws and a rakish white goatee.
