Shock collar
（重定向自Remote training）
The term shock collar is a term used in order to describe a family of training collars (also called e-collars, Ecollars, remote training collars, Zap collars, or electronic collars) that deliver electrical shocks of varying intensity and duration to the neck of a dog (they can also be applied to other places on the dog's body) via a radio-controlled electronic device incorporated into a dog collar. Some collar models also include a tone or vibrational setting, as an alternative to or in conjunction with the shock. Others include integration with Internet mapping capabilities and GPS to locate the dog or alert an owner of his/her whereabouts.
