sentence1: Shown on a test run with President Obama in the White House on March 15, 2009, the black-and-white Portuguese water dog is a gift to President Obama's daughters Malia and Sasha from Senator Edward M. Kennedy, who also owns Portuguese water dogs. Despite their lapdog looks, Portuguese water dogs are classified as working dogs. That means the pups seem to enjoy being given jobs that allow them to display their intelligence, strength, and stamina. "This breed possesses a lot of energy, so without training or a job to do, the dog may entertain itself by running full-speed down the West Wing or barking at Republicans," said animal behaviorist Mary Burch of the American Kennel Club.
sentence2: Bo is the new dog of President Obama.
