The SMART FENCE provides responsive boundary guidance to contain your dog(s) using your choice of Tone, Vibration, and/or Static Correction within a ¾-acre area — NO SUBSCRIPTION OR DATA REQUIRED to operate. It is the ONLY radio-frequency-based wireless e-fence that provides alerts via both audible beeps and app notifications via Bluetooth — offering 2-tier alerts: one WHEN YOUR DOG APPROACHES THE BOUNDARY, and another WHEN YOUR DOG CROSSES IT. The SMART FENCE is easy to install — simply mount the Control Station on an exterior wall at 6 feet or higher for optimal performance. Connect the free app to the Control Station via Bluetooth to easily configure your boundary size, receive alerts, and send e-collar commands as needed. You can manage up to two dogs simultaneously, keeping them safely within your designated area. The compact Control Station is a USB-C rechargeable battery, making it portable and perfect for outdoor use.
