Laddie Boy (July 26, 1920 – January 23, 1929) was an Airedale Terrier owned by U.S. President Warren G. Harding.

[2] Purportedly, the dog howled constantly for three days prior to President Harding's death in August 1923 at the Palace Hotel in San Francisco, knowing of his master's imminent demise.

In memory of President Harding and honoring his former employment as a paperboy, newsboys collected 19,134 pennies to be remelted and sculpted into a statue of Laddie Boy.

[6][7] After the president's death in 1923, Florence Harding gave the Airedale to Harry Barker, her favorite Secret Service agent.

[9] In the summer of 2012, Laddie Boy's unique collar, fashioned from Alaskan gold nuggets, was stolen from the Harding Home and Museum.
