This module explains how to safely and effectively introduce e-collar conditioning to retrievers, refining obedience and communication through precise timing, low-level stimulation, and consistent reinforcement. It covers essential setup principles, from proper collar fit and working level determination to overlaying stimulation on known commands like sit, here, heel, and kennel. Lessons focus on building confidence, maintaining control, and achieving fast, reliable off-leash responses. By the end of the course, handlers will understand how to use the e-collar as a clear communication tool that enhances—not replaces—positive training foundations.
