Wolves as pets and working animals
Though wolves are trainable, they lack the same degree of tractability seen in dogs. They are generally not as responsive as dogs to coercive techniques involving fear, aversion to stimuli, and force. Generally, far more work is required to obtain the same degree of reliability seen in most dogs. Even then, once a certain behavior has been repeated several times, wolves may get bored and ignore subsequent commands. Wolves are most responsive toward positive conditioning and rewards, though simple praise is not sufficient as in most dogs. Unlike dogs, wolves tend to respond more to hand signals than voice. Although they are more difficult to control than dogs, they can be easier to teach if the motivation exists.
Wolves are less suitable than dogs for working. Swedish wolf biologist Erik Zimen once tried to form a dog sled team composed entirely of wolves. The experiment failed as the wolves ignored most commands and were far more prone to fighting than sled dogs. North American wolves and wolf hybrids were used as experimental attack dogs by the South African Defence Force in Apartheid South Africa in an attempt to breed animals capable of tracking guerrillas. Because the wolves would not follow even basic commands, the experiment was abandoned. However, their sense of smell can rival that of established scent hounds. According to reports published in 2006, ongoing research at the Perm Institute of Internal Troops in Russia demonstrated that wolf/dog cross-breeds took 15–20 seconds to track down a target in training sessions, whereas ordinary police dogs took 3–4 minutes. Their success has led to plans to use them as police dogs for the Russian police.
Medieval hunting
Wolves were mainly hunted for their skins, to protect livestock, and in some rare cases to protect humans. Pelts were the only considered practical use for wolves, and were usually made into cloaks or mittens, though not without hesitation, due to the wolf's foul odour. There were generally no restrictions or penalties in the civilian hunting of wolves, except in royal game reserves, under the reasoning that the temptation for an intruding commoner to shoot a deer there was too great. In 9th-century France, Charlemagne founded an elite corps of crown-funded officials called "Luparii", whose purpose was to control wolf populations in France during the Middle Ages. In England of 950, King Athelstan imposed an annual tribute of 300 wolf skins on Welsh king Hywel Dda, an imposition which was maintained until the Norman conquest of England. The Norman kings (reigning from 1066 to 1152 AD) employed servants as wolf hunters and many held lands granted on condition they fulfilled this duty. King Edward I, who reigned from 1272 to 1307, ordered the total extermination of all wolves in the counties of Gloucestershire, Herefordshire, Worcestershire, Shropshire and Staffordshire, where wolves were more common than in the southern areas of England. James I of Scotland passed a law in 1427 requiring 3 wolf hunts a year between 25 April and 1 August, coinciding with the wolf's cubbing season. The wolf became extinct in England during the reign of Henry VII (1485–1509). Before its extinction in the British Isles, the wolf was considered by the English nobility as one of the five so called "Royal Beasts of the Chase".
