Bo (born October 9, 2008) is the pet dog of the Obama family, the First Family of the United States. Bo is a male Portuguese Water Dog. President 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 in part because Malia Obama's allergies dictated a need for a hypoallergenic breed. The White House has referred to him as the "First Dog", a US cultural term occasionally used during recent administrations.
Portuguese Water Dogs are originally from the Portuguese region of the Algarve, from where the breed expanded to all around Portugal's coast, where they were taught to herd fish into fishermen's nets, to retrieve lost tackle or broken nets, and to act as couriers from ship to ship, or ship to shore. Portuguese Water Dogs were often taken with sailors during the Portuguese discoveries.
