Sasha and Malia Obama finally got their White House puppy this week, when the First Family adopted a 6-month-old Portuguese water dog. The girls named the dog Bo. Although President Obama had initially expressed interest in rescuing a shelter dog, Bo is a purebred selected for his hypoallergenic coat. Sen. Edward Kennedy’s wife, Victoria, presented the dog as a gift. To appease those clamoring for a shelter dog, the Obamas said they would make a donation to the D.C. Humane Society.
