Dog collar, electric dog fence, escape collar with 2 collars

Product Description: Safe, reliable, and humane dog containment, this hidden fence system is among the most reliable and cost-effective pet containment systems available. When installing the wire, 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 more than 20 seconds at a time. If your dog stays too close to the wire, it will not know how to back away or move away from it. Please train your dog to stay away from the wire. If the wire (300 meters) is too long for the perimeter of your yard, you can trim 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 circle must be greater than 10 meters; otherwise, the signal will be too strong, and the control box will remain constantly alarmed. 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 weaken. 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 English Instruction Manual
