Franklin Delano Roosevelt
Dogs in the White House are nothing out of the ordinary, but a dog at the signing of a war declaration? That would be Fala, Franklin Roosevelt's black Scottish terrier, who was a constant companion to the president -- even in December 1941 when the nation entered World War II. In 1944, Fala traveled with the president to the Aleutian Islands, a trip that would live on in presidential infamy. Rumors swirled that Fala was somehow left behind, and Roosevelt sent a destroyer back for him, costing taxpayers millions of dollars. FDR answered critics with the famous "Fala speech" on September 23, 1944, in which he vehemently denied the rumors.
