For the future, when i build the wattle fence, the plan is to run two sets of wires - actual wires - along the fence. One set of wires at the bottom of the fence ~30cm (1') above ground and another one at the height of a deer nose to keep the deer away from my salad and kale. I am thinking about one hot wire with one ground wire above and below.I know this is a bit into the future- but I would stick with keeping the electric line on the outside (the side that faces the threat) - at a spot the animal would have to touch before attempting to scale your waddle fence.
Getting shocked by the fence requires contact with the ground... and all the better if there is moisture in the ground. The reason birds can stand on electric lines and live to tell about it is because there's no ground contact.
You can, of course, put a wire at/near the top, but I would still offset it onto the side the dog comes from (as opposed to the apex of the fence), say 3-5" out in front of the top of the fence. Again- depending on the height - for the dog (or other invader) to get the deterrent shock up there, you'll have to run a separate wire that connects to the ground wires, and those two will have to be close enough that once off the ground, the critter touches both of them at once to be shocked.
The height of my artwork abilities below: The maroon box is the fence energizer. There are two connections on the box. My green line is the ground wire. The ground wire goes to your metal ground rods (the purple lines, pounded into the ground). The ground wires are wired together with ground rod clamps, and put in a spot that ideally stays nice and moist. The red one (the "hot" wire) goes to the polywire and is where the electric pulse does its work.
If you keep all the polywire at the level where the dog's feet are still on the ground to deter it from climbing, then the ground wire stops at the ground rods, at the 3rd yellow spot.
If you intend to put an electric wire all the way up top, where the dog's feet would no longer be touching the ground (the wood fence won't count as being on the ground) you need a separate wire run from the ground rods down the length of the fence at the top positioned so the dog would have to touch both the line from the ground rods and the polywire itself before making it over the fence. Otherwise, it's not going to get much of a shock up there- if any.

And each set of wires will be driven by a separate fence electrifier, just in case if one breaks.
I am also thinking of running an additional wire on top of the fence and hook it up to my tesla coil. The light effect would be crazy and deter everybody, humon's inclusive.
