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.
Man-eater
Contrasted to other carnivorous mammals known to attack humans for food, the frequency with which wolves have been recorded to kill people is rather low, indicating that, though potentially dangerous, wolves are among the least threatening for their size and predatory potential, except for the dog which poses lethal hazards for reasons other than predation. In the rare cases in which man-eating wolf attacks occur, the majority of victims are children. Habituation is a known factor contributing to some man-eating wolf attacks which results from living close to human habitations, causing wolves to lose their fear of humans and consequently approach too closely, much like urban coyotes. Habituation can also happen when people intentionally encourage wolves to approach them, usually by offering them food, or unintentionally, when people do not sufficiently intimidate them. This is corroborated by accounts demonstrating that wolves in protected areas are more likely to show boldness toward humans than ones in areas where they are actively hunted.Attacks on humans by dingoes are rare, with only two recorded fatalities in Australia. Dingoes are normally shy of humans and avoid encounters with them. The most famous record of a dingo attack was the disappearance of nine-week-old Azaria Chamberlain. Her parents reported that they both saw a dingo taking Azaria out of their tent when she and her family were out on a camping trip to Uluru.
