First lady Michelle Obama had a personal tweet about Bo, the White House dog, who turns four today:

 

It’s a big 4th birthday for Bo! He’s getting some extra treats today. –mo

Here are five cartoons from our archives about Bo, the Portuguese Water Dog that was a gift  from the late Sen. Ted Kennedy (D-Mass.) and wife Vicki. At the time, the Obama administration was caught up in a scandal of several staffers owing hundreds of thousands of dollars in back taxes, so you see that cropping up in a couple of the cartoons:
