Create a safe and independent space for your dog with this electric dog fence system. Featuring buried wires and a wall-mounted transmitter, it effectively trains dogs to stay within designated boundaries, protecting furniture and ensuring peace of mind. This system supports automatic training, delivering a beep and then a safe stimulation when your dog approaches the wire; the intensity increases as they get closer. Adjustable control range up to 1.2 acres (53189 sq ft) allows customization to fit your yard. A wire break alert notifies you of any disruptions, and a low-battery indicator ensures consistent operation. Compatible with multiple dogs (up to 3 collars with one transmitter), making it ideal for households with several pets. The receiver collar is suitable for dogs weighing 4lbs+ with neck sizes from 7.5in to 17.92in. Includes a 4LR44 6V battery providing up to 10 days of runtime. Choose short probes for short-haired dogs and long probes for long-haired dogs. Proper installation involves designing your containment area, installing the transmitter, laying out the perimeter wire, and testing the system. Always supervise your dog during initial training and limit collar wear to 12 hours daily. Note: The fence is activated when a dog approaches within 0.5m (1.64ft) at a moderate speed.
