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.
Wildlife smuggling
Exotic pets are animals desired by consumers and are rare or simply not easily available in the owner's region. Television shows and movies can make certain animals popular. While many of these animals can be obtained from legal sources, many animals are captured from their native environments, smuggled across national borders, and wind up in family homes, menageries, or roadside circuses. Reptiles, such as bearded dragons and geckos, and birds, such as scarlet macaws and certain falcons, make up the largest share of animals captured and sold. Exotic mammals including three-toed sloths, sugar gliders, prairie dogs, hedgehogs, and other animals are kept as pets. "Birds are the most common contraband; the State Department estimates that two million to five million wild birds, from hummingbirds to parrots to harpy eagles, are traded illegally worldwide every year." Tigers are a popular pet. An estimated 5,000 to 7,000 tigers (2013) are kept in the United States. The range of numbers is due, in part, to the lack of required reporting in some areas. For comparison, less than 400 of these big cats are in U.S. zoos accredited by the Association of Zoos and Aquariums and 3,200 live in the wild. Tropical fish, nonhuman primates, and other animals are also part of the illicit pet trade. The U.S. has very strong natural animal and plan laws. Ivory is the hardest thing to bring in the US.. You cannot buy pearls out of state and bring them in. Most of the countries that have animal laws use the template of CITES. If any animal has outside animal parts coming in, the US will not import it.
