Protect your dog with the Halo Collar 3, featuring virtual fences and advanced real-time GPS tracking. Instantly create wireless dog fences with a few taps of your finger — no installation required. The Halo Collar communicates with satellites to continuously monitor your dog’s location at all times. When your dog approaches a Halo fence, they will receive feedback of your choice, which escalates as they get closer. If your dog is outside of the fence, encouragement feedback will guide them back to safety. The fences will work everywhere you go — even in locations without Wi-Fi or cellular connection. Train your dog to understand their boundaries, with a training program developed by world-renowned dog behaviorist Cesar Millan.
