Wolves learn to avoid certain prey animals because nature has endowed them with specific defenses. The skunk and porcupine are classic examples of animals that wolves learn to avoid. The Times-Union labeled the use of electrical stimulus as torture. This word is inaccurate. It is emotionally charged and implies that evil men are hurting innocent animals for some sort of sadistic pleasure.
Torture involves hurting an animal, giving the animal no option but to endure the pain.
Punishment involves causing only the minimum amount of discomfort so as to encourage the animal to desist the unwanted behavior. In other words, as soon as the wolf begins the pursuit of the domestic livestock, it will receive a mild electronic stimulus. This stimulus will hurt somewhat, but it will be enough to dissuade the wolf from continuing its pursuit. The wolf will learn very quickly how to avoid the punishment by avoiding the livestock.
