I didn't think France had capital punishment.

There was a report a couple of months ago of a guy who climbed a fence to paint graffiti on some kind of power substation (there were warnings all over the fence of course). The charge ran up the stream of paint from his aerosol can and electrocuted him.
Mythbusters actually tested the fence thing for humans at least. You have to be pretty close, however, or the urine stream beaks up and can no longer conduct electricity. They found that peeing on the third rail of a subway didn't work because of the distance. A dog would probably get close enough.
The graffiti artist was in Santa Fe, New Mexico. He "succumbed [in May, 2007] to third-degree burns he suffered after trying to spray-paint on a high-voltage transformer inside a Public Service Company of New Mexico substation near Buckman Road. Officials say a stream of spray paint could have caused 115,000 volts of electricity to arc into his body, leaving him only partially clothed and burned on most of his body."
