From Wonderwall who apparently got it from US:
"The Obamas are finally welcoming their puppy this Tuesday! The black Portuguese water dog comes from a kennel in Texas. It was sold to a family who gave it back, so will be "re-homed" to the first family, TMZ.com reports. The six-month-old dog is named Charlie, but the Obamas will rename it. The dog will be presented to the family by Senator Ted Kennedy, who has purchased his own pups from the same kennel. Sasha and Malia's new pet is from the same lineage as the Kennedy dogs, the Web site reports. The first pet's arrival has been a hot topic since the president promised his girls a puppy the night he was elected. After taking office, Obama said they'd get a pooch in the spring because the warmer weather would make his daughters more apt to walk it."
Of course that pic isn't the exact dog, I was just curious as to what such a pooch would look like. No doubt there will be a run on them soon!
