An addition for a wrought iron fence to discourage dogs from digging under the resulting modified fence. The addition has a horizontal support bar affixed to the fence near the bottom of the fence. Guide tubes are vertically held to the horizontal support bar, close enough to prevent the passage of a dog between adjacent guide tubes. A spike is inserted into each of the guide tubes and driven into the ground to provide an underground barrier. The present invention is also for the process of using the addition, including the steps of attaching the horizontal support bar to the fence. Next, a spike is inserted through each of the guide tubes. Lastly, the spikes are driven into the ground to form the underground barrier. An O-ring may be placed over the spikes above the guide tubes to limit the downward movement of the spikes for use, for instance, in a gate. Also, an O-ring may be placed over the spike below the guide tube to prevent the lifting of a spike by a dog.
