Dog, A Man's Best Friend

In 1870 Warrensburg, Missouri, George Graham Vest represented a farmer suing for damages after his dog, Old Drum, had been shot and killed. Vest’s closing speech included this quote, “The one absolutely unselfish friend that a man can have in this selfish world, the one that never deserts him and the one that never proves ungrateful or treacherous is his dog.” In 1958, a statue of Old Drum was erected on the Johnson County Courthouse lawn containing a summation of Vest’s closing speech, “A man’s best friend is his dog.”
Much earlier, however, Voltaire had written in his Dictionnaire philosophique of 1764:
CHIEN. —- Il semble que la nature ait donné le chien à l'homme pour sa défense et pour son plaisir. C'est de tous les animaux le plus fidèle : c'est le meilleur ami que puisse avoir l'homme.
