Be sure to warn any friends that come over not to touch it (although that is
an
excellent way to check that it is still working.......)

And by all means, don't pee on it!

Actually, we used to spend some time on a farm, where the neighbour had cattle
fences (we raised horses, so didn't use electric fences).

Our dog was a city dog, and the first time we took him out to the farm, he did
what dogs do, and raised his leg on a fence post that happened to have an
electric fence attached to it. He only did it once, and all of the men within
hearing sort of went into a half crouch and winced in sympathy when they
saw/heard the result. One unhappy puppy.

The same Mennonite lady next door had her electric fence unit break down. In a
fit of over-zealous thrift, they hooked up a house power source via some sort
of transformer instead of replacing the unit.

When a cow touched the new 'thrift' version, it was obvious that they had got
the wrong mix of amperage and voltage, as it knocked the cow to it's knees.

Heaven knows what would have happened to our pooch, had he chosen to whizz on
THAT version of the electric fence.....
