Washington - President George Bush and the first lady are welcoming a new addition to the family: a Scottish terrier puppy named Miss Beazley.

White House spokesperson Scott McClellan said the puppy is Bush's birthday gift to his wife, Laura, who turned 58 on Thursday.

Born on October 28 this year, Miss Beazley will arrive at the White House just before the Christmas holiday, McClellan said.

The first family already has a Scottish terrier named Barney and a black cat named India.

One of the first family's dogs, an English springer spaniel named Spot, died in February.

McClellan said Miss Beazley was named after a dinosaur in a popular children's book. He said the puppy's father is Barney's half-brother.
