Bo Obama: Three Adorable Years In The White House, Stumping For Four More (PHOTOS)

WASHINGTON -- Awwww. It's been an adorable three years since Bo Obama, the First Family's pet Portuguese water dog, first took up residence in the White House.

Bo Obama first arrived at the White House on April 14, 2009. The six-month old had been returned to his breeder by a previous owner; he was then given to the Obama family as a gift by late Sen. Ted Kennedy (D-Mass.).

The first three years have been so good that the handsome black and white dog is stumping for four more, doing his part to help the president's reelection campaign by appearing in a campaign ad.

As you can see in the slideshow below, Bo is not just a political friend -- he is an overall loyal companion, accompanying the Obama family on vacation and to White House events like the annual Easter Egg Roll. And sometimes he's found doing normal dog things, like playing fetch, riding Air Force One and hanging around the Oval Office.
