Bo (October 9, 2008 – May 8, 2021) was a pet dog of the Obama family, the former First Family of the United States. Bo was a neutered male Portuguese Water Dog.
Barack Obama and his family were given the dog as a gift after months of speculation about the breed and identity of their future pet. The final choice was made partly because Malia Obama's allergies made a hypoallergenic breed necessary.
Bo was occasionally given the title "First Dog of the United States of America". In August 2013, Bo was joined by Sunny, a female dog of the same breed.
