Her name is Sunny, and she's the first family's second adopted dog. She was born in Michigan last year and arrived at the White House on Monday.
Sunny is a Portuguese Water Dog -- the same breed as the Obamas' other dog, Bo. The White House says the breed works well for the Obamas because of family allergies.
Sunny is expected to join Bo for evening walks and the occasional Oval Office huddle with the president.
