You can use a tie down and attach a long cable to the dogs harness. We tried that with our dog, but he's older and would just sit instead of running around. So we just take him out for walks a couple of times a day.

One thing about electric fences is that some dog rescues do not allow for their use. Our neighbor had one and his dog would get spooked and then bolt through into our yard. Once he did that, he wouldn't go back.
