Bo and Other Presidential Dogs

Abraham Lincoln and Fido
This floppy-eared rough-coated dog of unknown ancestry lived with Lincoln in Springfield, Ill., for the five years before he became President. Upon his election, Lincoln decided that the dog would not survive the trip to Washington and, despite the objections of his son Tad, left Fido in Illinois. When Lincoln's body was returned to Springfield, Fido was brought out to meet the mourners.
