waterdogU.S. President Barack Obama has reportedly honoured his election pledge to reward his daughters with a pet dog.

The “first puppy” is a six-month-old black-and-white Portuguese water dog that the Obama girls have named Bo, according to Zoogle News affiliate pregnant-pauses.com, reporting a story in the Washington Post. Obama promised Malia, 10, and Sasha, 7, a puppy in his first speech after winning the presidency as a reward for their behaviour during the election campaign.

The water dog, which does not shed hair, is said to be less aggravating for Malia who suffers from allergies.

The identity of the puppy – which had been one of Washington’s best kept secrets – will be officially revealed by the White House on Tuesday, the Post reported.

Bo was a gift to Obama’s daughters from close family friend, Democratic Senator Edward Kennedy. He owns three Portuguese water dogs.
