Did you hear President Obama retelling how his young daughters took the news of his Nobel? "You got the Nobel Prize, and it's Bo's birthday, and we get a three day weekend." Something like that. I had to smile at the sheer excellence. Of course the dog's birthday is right up there.
And Bo is right at the end of a fine short slideshow of Presidential dogs past and present you'll find at NPR.org. Dogs we know well - FDR's Fala, the Clintons' Buddy, George H. W. Bush's Millie - are in there.
So are a few others I did not know as well. Say what you will about Herbert Hoover, his King Tut was clearly a good friend to him. I had forgotten Gerald Ford's Liberty, who has one of the cutest faces in the lineup. And I never knew Nixon had a Yorkie named Pasha. Have a look at the show.
