Electric Dog Fence with 2 Collars - Anti-Escape Collars for Effective Training

Product Description: Does your dog run away? Does your dog get lost? This system allows you to define an invisible safety perimeter around your yard so your dog can't cross it. A secure, reliable, and humane dog containment solution, this hidden fence system is among the most reliable and cost-effective pet containment systems available. Voltage: 100V-240V. Transmitter (the box): 12V. Receiver (the collar): 9V. Receiver (the collar) + strap + battery = 112g (the 9V battery is not included). If your pet is large or heavy, the system may be too heavy for them. If your pet is very small, the collar may be a bit heavy for them. This wire can be buried, laid on the ground, or attached to an existing barrier/fence. When installing the wire, you can pull it from the reel one end at a time and install it underground, avoiding stones. Caution: The dog should not wear the collar for more than 12 hours a day. The electric shock should not last longer than 20 seconds each time. If your dog always stays near the wire and doesn't know how to back away or move away from it, please train it to develop the habit of staying away from the wire. The 300-meter wire covers large areas and includes two waterproof and adjustable collars. If the wire (300 meters) is too long for the perimeter of your yard, you can cut it to a shorter length. However, the total wire length must be at least 50 meters; otherwise, it will cause a short circuit. The diameter of the loop must be greater than 10 meters; otherwise, the signal will be too strong, and the control box will remain in alarm mode. If you want to replace the 300-meter wire with your own, the total wire length must not exceed 500 meters, otherwise the signal will be weakened. Your dog will always stay within your yard! Package includes: 2x Waterproof & adjustable collars, 1x remote transmitter, 1x power connector (EU plug), 1x 300-meter wire, 2x small test lights, 2x screws, 2x screw pullers, 4x additional metal contact points, 20x training flags, 1x instruction manual in English
