Presidents and Their Dogs

Barack Obama and Bo
On April 12, The Washington Post reported that the Obamas had accepted the gift of a Portuguese water dog from Senator Edward Kennedy and his wife Victoria. Malia and Sasha Obama have named the six-month old first pet Bo because they have cousins with a cat of the same name and because Mrs. Obama's father was nicknamed Diddely, after the famous bluesman Bo Diddley.
