The lovable White House Portugese water dog turns four years old on Tuesday, and he has grown a LOT since his days as a puppy in the White House.
In his short spell at 1600 Pennsylvania Avenue, Bo's already chilled with Oprah, worn costumes, gotten his own Beanie Baby, pulled some pranks and made friends with Betty White -- and he even gets to sleep in the bed every now and then.
So, four years in, what's Bo's approval rating? Well, the presidential pup has gotten some very high praise. "He is the smartest dog on the planet," the first lady told David Letterman back in March. "He is my son. I have two girls and a boy ... He's very well-mannered, he's very even-tempered. He has a busy schedule, I mean appearances... we're thinking about getting him an agent."
Below, our birthday tribute to the great Bo Obama: his cutest moments caught on tape. (JUST WAIT until you see Bo's high-five skills.)
