The identity of the first puppy leaked out Saturday. The White House tried to delay the news until the big debut planned for Tuesday afternoon.

So as is the practice with adopting families, DogOscopes are celebrating the day Bo joins his own family …. his Gotcha Day … and make him an honorary Arfies the Aries.

The first pup is a 6-month-old Portuguese Water Dog given to the Obama girls as a gift by Senator Edward M. Kennedy of Massachusetts, who loves Portuguese Water Dogs himself. The girls named it Bo — first reported by The Washington Post.
