Fido

Fido was a yellow mixed-breed dog owned by Abraham Lincoln and kept by the family for a number of years prior to Lincoln's presidency, and became a presidential pet during Lincoln's presidency, although he remained in Springfield, Illinois. Fido came to wider notice through the scholarship of T. D. Bancroft who was the first writer to publish content about Fido in a pamphlet published about Lincoln at the time of the United States' centennial in 1876.
