Can Aggression in Dogs Be Elicited Through the Use of Electronic Pet Containment Systems? Richard Polsky, 2000 Polsky presented a set of five case reports based on data from legal documents relating to personal injury lawsuits involving severe attacks on humans by dogs who were being trained or maintained on an electronic pet containment system (using a shock collar). In every incident, the dog was within the "shock zone" and all fences were working; the dogs must then have received a shock. Four of the five dogs were not subject to threatening behavior by the victims prior to the attack. None of the dogs gave any kind of warning prior to biting, and all bit their victims repeatedly and seriously in the head, face, back and neck. The analysis suggests that the dogs' aggression was caused by the shock. There are several unknown factors to the cases, including the training used to introduce the dog to the fence, the amount of time the dog spent outside unsupervised, and what level of shock intensity the dogs received. However, the reaction of the dogs, and especially the severity of the attacks, was inconsistent with their past behavior. Polsky concluded a "possible interpretation in terms of unconditioned aggression as a result of a dog having received electronic shock and avoidance-motivated aggression mediated through fear reduction toward human stimuli."electric pet containment systmes?
