This document provides instructions for using an anti-bark collar that delivers progressively increasing tones and shocks to stop a dog from barking. It works by sensing each bark with a microphone and delivering a warning tone for the first bark, a stronger tone for the second, and a tone plus mild shock for the third. If barking continues, the intensity increases through three levels of shock correction. It is meant to teach dogs that barking causes discomfort through negative reinforcement.
