The First Family introduced their new little puppy to the public on Monday.
Sunny is the same breed as 4-year-old Bo, who was a gift to the Obamas from the late senator Ted Kennedy.
“Sunny was born in Michigan in June 2012, and arrived at the White House today,” read the announcement on the White House blog.
“Sunny is the perfect little sister for Bo – full of energy and very affectionate – and the First Family picked her name because it fit her cheerful personality.
“We suspect Sunny will follow in Bo’s footsteps and keep the President company in the Oval Office, go for walks with the First Family after their 6:30 family dinner and even jump up on the First Lady’s lap from time to time!”
President Obama and First Lady Michelle Obama tweeted pictures of Sunny on Monday to introduce their new family member.
The White House said the Obamas are making a contribution to the Washington Humane Society in honor of Sunny.
The White House also released a video of Bo and Sunny playing together on the lawn.
