This works, but please be aware of safety considerations. Use an
approved electric fence system: Never connect a bare wire to an outlet.
Place signs on the fence warning people about it. People can sue you:
dogs can't (although their owners can).

Electric fence systems can be purchased at most farm supply places like
Agway. The electric fence is current limited so that it won't harm
animals or humans getting in contact with it (other than the possibility
of damage from a tool you're holding when you touch the fence). The
smaller ones can be shorted out by weeds growing into the fence and
conducting away the voltage.
