*The First Family announced on Instagram Monday evening that they’ve added another addition to the family.

The White House is now home to new 1-year-old female pup Sunny, a Portuguese water dog just like her big brother Bo. (The hypoallergenic breed doesn’t trigger 15-year-old Malia Obama’s allergies.)

Sunny was born in Michigan last June, and arrived at the White House on Monday (Aug. 19), according to whitehouse.gov.

“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,” reads the website.

If Bo’s active social calendar is any indication, Sunny will likely join her family (and big bro) on official duties like visiting Walter Reed and the Children’s National Medical Center, and participating in the inspection of the family’s holiday decorations and at the annual Easter Egg Roll.

Bo joined the Obama family in 2009, and celebrated his fifth birthday in October. Just one month after that big milestone, President Obama alluded to the fact that he’d remain an only child – telling his daughters in his post-election victory speech that “for now, one dog’s probably enough.” He has since flip-flopped.

In honor of Sunny’s arrival, the Obama family is making a donation to the Washington Humane Society.
