The only way to cancel the signal in a certain area of the Boundary Area is to install a Double Loop Layout (FIGURE 2F) and twist the two parallel boundary wires together in the area where you need the the signal to be cancelled.

Does an electric dog fence have to make a complete loop?

The answer is no, an electric fence DOES NOT have to make a complete loop. However, there are advantages and disadvantages to completing the fence loop. Creating a continuous loop will increase voltage on the fence line, because power is pushed in both directions.
