Man's best friend (phrase)

"Man's best friend" is a common phrase about domestic dogs, referring to their close relations, loyalty, and companionship with humans. The first recorded use of a related phrase is by Frederick the Great of Prussia. It was likely popularized by its use in a poem by Ogden Nash and has since become a common colloquialism.

Before the evolution of wolf into dog, it is posited that humans and wolves worked together hunting game. Wolves were the superior tracker but humans were the superior killer; thus wolves would lead humans to the prey and humans would leave some of the meat to the wolves. This working relationship eventually led to the evolution of dogs, though there is controversy as to the exact nature of that transition. Some say wolves evolved naturally into dogs, wherein the wolves that worked best with humans slowly began to assimilate and pass their domesticated genes down. Others say that humans took wolf pups and raised them to be domesticated. Either way, humans and dogs formed a working relationship.

In Homer's Odyssey (c. 8th century BC), upon Odysseus' return, his beloved dog Argos is the only individual to recognize him. Odysseus anonymously asks his old friend, "Eumaeus, what a noble hound that is over yonder on the manure heap: his build is splendid; is he as fine a fellow as he looks, or is he only one of those dogs that come begging about a table, and are kept merely for show?" "This dog," answered Eumaeus, "belonged to him who has died in a far country. If he were what he was when Odysseus left for Troy, he would soon show you what he could do. There was not a wild beast in the forest that could get away from him when he was once on its tracks. But now he has fallen on evil times, for his master is dead and gone, and the women take no care of him." Unable to greet his beloved dog, as this would betray who he really was, Odysseus passed by (but not without shedding a tear) and entered the well-built mansion, and made straight for the riotous pretenders in the hall. But Argos passed into the darkness of death, now that he had fulfilled his destiny of faith and seen his master once more after twenty years. This story shows both companionship and neglect towards dogs amongst humans.
