What breed of dogs are in the White House?

The Obamas have one dog with them at the White House, a neutered male Portuguese Water Dog named Bo. The Obamas chose Portuguese Water Dogs in part because they are hypoallergenic, meaning they are unlikely to trigger allergic reactions in Malia, one of President Obama's daughters who is allergic to dogs.

Bo was gifted to the Obamas by the now late Senator Ted Kennedy.

Additionally, the United States Secret Service (which is entrusted, among other duties, with personally protecting the President and are near him at all times wherever he is, whether at the White House or elsewhere in the world) uses Belgian Malinois dogs (otherwise known as Belgian Shepherds) exclusively for their work.
