Barney, former White House Scottie, dies
Later videos later included Miss Beazley, the Bush family's other Scottish terrier, and high-profile cameos by country singer Alan Jackson and former British Prime Minister Tony Blair.
A burial is planned at the former president's ranch in Central Texas, where Bush says Barney, "a fierce armadillo hunter," loved to accompany him while fishing for bass.
Barney politely greeted heads of state, queens and prime ministers but "guarded the South Lawn entrance of the White House as if he were a Secret Service agent," Bush added.
Barney was the continuation of a Bush family tradition of presidential dogs begun by Millie, the springer spaniel brought to the White House by President George H.W. Bush and his first lady Barbara Bush.
