WASHINGTON - Bo the Portuguese water dog makes his official move into the White House today.

How President Barack Obama and his family introduce him to his new home - and the world - will say much about their skills as novice dog owners.

The White House will be the puppy's fourth home in his six months of life.

He was born in Texas, then moved to his first owner's home in Washington, D.C., then spent nearly a month with Senator Edward Kennedy's dog trainer in Virginia.

Next stop is 1600 Pennsylvania Avenue.

The dog's breeder and a spokeswoman for Michelle Obama say Kennedy and his wife gave the dog to the Obamas' daughters - Malia and Sasha - as a gift.
