How to Install an Underground Dog Fence

When you install an underground wire fence, you get an easy and inexpensive way to contain your pet. It allows your pet to have the freedom to roam around your yard, while staying safely within it. An electric fence is a great alternative to traditional fencing that is far more expensive. An in-ground fence also is a great solution for neighborhoods that won’t allow you to have a traditional above ground fence. An underground fence works by a wire that sends a radio signal along the wire that has been buried in the yard. Your dog wears a special receiver collar which is designed to pick up the radio signal. As your dog approaches the boundary, he will hear a warning beep. If he continues to go on, he will receive a mild correction. Installing an underground fence is a relatively easy thing to do.


  1. 1
    Using a pencil and paper, draw a map of your yard. Draw where you want the boundaries of your electric fence to be.
  2. 2
    Check your transmitter location. Be sure that it is at least 3 feet from objects such as water heaters as they may get in the way of receiving a strong signal from the wire. Following the manufacturer’s instructions, use the screws and hardware given by the manufacturer to mount the transmitter onto the wall.
  3. 3
    Connect the twisted fence wire into the transmitter. Go ahead and plug the transmitter into your electrical outlet and turn it on. A light will come on if you are connected with a circuit.
  4. 4
    Insert the batteries into the pet collar and turn it on. It is not time to put it on your dog just yet.
  5. 5
    Go over to the transmitter and set the boundary control dial to be as wide as you can. Look at the manufacturer’s instructions to make sure you have set it according to their recommendations.
  6. 6
    Test to make sure the collar is working in conjunction with the wire. Hold the test light strip that was given to you with your kit up against the contact points on the dog’s collar. Walk over to the boundary wire, holding the collar at the same level as their pet’s neck. Listen for a beep or watch for it to light up as you enter the boundary zone. If the collar didn’t do this in located you wanted it to, turn the boundary dial knob to a different setting. Do this again, until the collar beeps where you want it to, closer or further away from the boundary wire.
  7. 7
    Using a shovel or lawn edger, create a trench that is around 3 inches deep to place the boundary wire. Push the wire down into the groove and cover the wire with dirt.
  8. 8
    Take your boundary flags and place them every 10 feet to mark where you have put your dog fence wire. These can be removed later, after your dog learns where his boundaries are.
  9. 9
    Remove the battery from the collar. Fasten the collar around the dog’s neck, letting the metal contact points touch your dog’s skin. They should be centered underneath your pet’s neck. The collar should fit securely, but be loose enough to be able to insert your finger in between the contact points and your pet’s neck.


  • Read the manufacturer’s instructions about how to train your dog to use the electric dog fence.


  • Read the instructions given by the manufacturer regarding handling the pet collar and setting it for use.
  • Only use the collar on a dog, never test it out on a human.
  • While testing the collar, be sure not to touch the metal contact points.
