It was always considered that wolves, and other dogs that live in wilderness, will kill livestock as soon as they get the chance. In direct, immediate and cruel way of terminating canids, humans turn to various techniques: killing them with fire or cold weapons and stakes, in some terrains from the ground, sometimes even from helicopters or planes; by insidious use of poisons, nooses, traps set by so-called trappers. Canids go through enormous stress when caught in a trap and other animals get caught very often as well. It is usual to take cubs out from dens and kill them. They get killed not only because of livestock, but also for meat, skin, fur, teeth, even sport, circus shows, lab experiments, keeping in zoos and other means of imprisonment.
Many wild canids were killed, and are still being killed, for their very beautiful hair and lovely colours. Wolves and Egyptian Wolves were killed for their fur. Foxes were better known, throughout history, as clothing item of so-called aristocracy, rather than animals from wilderness. Raccoon dogs are very much appreciated among traders for their fur, so they are bred and kept in captivity.
During wolf hunting, humans use dogs. Many domestic dog breeds were created for wolf hunting. In the eyes of hunters, forest and meadow should only exist because of the game. It should be noted that removal of one specimen can affect destiny of the whole pack, which can have catastrophic consequences for ecosystem and the food chain.
In Australia, in order to control the number of Dingos, contraceptive vaccines are being used, or better, viruses in form of a shot that cause something within immune system to block growth of an embryo, something that destroys it.
