Electric Fence? Yes or No? Opinions?

It's not a shock it's a high level of vibration.
The lowest setting would feel like a phone vibrating.

Yes, that might be. But for it to be effective the dog has to at least once feel the pain of the actual shock which comes after the vibrating. For most dogs I imagine they would have to feel the pain several times before they get the message and heed the vibrate only.

Rachel - get 2 x 4s, a roll or two of wire fencing and build a dog run. Even better if a dog door leads from the house to the run. I understand from others that it can be done inexpensively, and you can use it for a long time. You can always take your doggies on walks and runs outside the "run".
