untold story: medieval times

Middle Ages

Greyhounds nearly became extinct during times of famine in the Middle Ages. They were saved by clergymen who protected them and bred them for the nobility. From this point on, they came to be considered the dogs of the aristocracy. In the tenth century, King Howel of Wales made killing a greyhound punishable by death. King Canute of England established the Forest Laws in 1014, reserving large areas of the country for hunting by the nobility. Only such persons could own greyhounds; any "meane person" (commoner) caught owning a greyhound would be severely punished and the dog's toes "lawed" (mutilated) to prevent it from hunting. The value of a Greyhound exceeded that of a serf, and the punishment for causing death of a Greyhound was equivalent to the punishment for murder. In 1066 William the Conqueror introduced even more stringent forest laws. Commoners who hunted with greyhounds in defiance of these laws favored dogs whose coloring made them harder to spot: black, red, fawn, and brindle. Nobles by contrast favored white and spotted dogs who could be spotted and recovered more easily if lost in the forest. It became common among the English aristocracy to say, "You could tell a gentleman by his horses and his greyhounds." Old paintings and tapestries of hunting feasts often include greyhounds.
Hunting in Europe and Asia with specially bred and trained dogs was the sport of nobles and the clergy, in large part because they owned or controlled much of the land suitable for hunting. There's little evidence that the common man in the Middle Ages used dogs to hunt. Hunting with sighthounds in this era hadn't changed much since the time of Romans like Arrian. It was a sport, not the serious pursuit of food, which pitted the hounds against the hare and against each other.
Dogs in general were at times looked down upon in the Middle Ages, while greyhounds were highly valued. Vincent of Beauvais, in the mid- thirteenth century, identified three types of dog: hunting dogs, with drooping ears, guard dogs, which are more rustic than other dogs, and greyhounds, which are "the noblest, the most elegant, the swiftest, and the best at hunting."
The greyhound was used as an emblem, often in tombs, at the feet of the effigies of gentlemen, symbolizing the knightly virtues (faith), occupations (hunting) and generally the aristocratic way of life. Where tombs are concerned, the greyhound always was associated with knighthood (along with the lion, symbolizing strength) and never with ladies, who generally were associated with the little lap-dog (symbol of marital faithfulness and domestic virtue).
The greyhound is the first breed of dog mentioned in English literature. The monk in Geoffrey Chaucer's 14th century The Canterbury Tales reportedly spent great sums on his greyhounds:

Greyhounds he hadde as swifte as fowel in flight;
Of prikyng and of huntyng for the hare
Was al his lust, for no cost wolde he spare.

Edmund de Langley's Mayster of Game, AD 1370, describes the ideal greyhound ( read an excerpt). Langley presented this book to the future King Henry V of England. Henry reportedly was a big fan of greyhounds; perhaps Shakespeare knew this when, two centuries later, he had Henry speak the quote below.
We don't know for certain where or when the term greyhound originated. It probably dates to the late middle ages. It may come from the old English "grei-hundr," supposedly "dog hunter" or high order of rank. Another explanation is that it is derived from "gre" or "gradus," meaning "first rank," so that greyhound would mean "first rank among dogs." Finally, it has been suggested that the term derives from Greekhound, since the hound reached England through the Greeks. A minority view is that the original greyhound stock was mostly grey in color, so that the name simply refers to the color of the hound.
