Mr. Om says he uses a double hot wire around his yard. Does that mean
two hot wires, or one hot and one ground? Grounding isn't an issue?

Ms. Om. ;-)

2 strands. One about 4" high and one at about 14" up.
This keeps her from going _under_ or over the wires.

Honestly, I've never seen a dead bird in my front yard and the wires
keep the border collie from going over the fence.

Those dogs can JUMP!!!
