I was thinking of a solenoid coil used in washing machine to turn the water on and off. They are cheap. I as also thinking that the voltage spike might two or three thousand volts. The voltage spike occurs when the voltage supply is turned on or off, but no spike when the coil has power or is off, only when change happens is their a voltage spike. A friend of mine, when I was a teenager had a book with an aluminum foil cover. When you opened the book or cclosed the book, you got a little bite.

John's ideas are interesting, that solenoid coil would have to have a lot of turns on it, I'm not sure dogs responde to even moderate electric shocks as much as humans do, I think they need say 600 volts or so to make them take notice. I like the meat tray and pans idea except it'll wak up everyone in the house too. Maybe just a wireless baby monitor placed near the plate would give you enough sound to start yelling at him. What you don't want is false positives, if the thing goes off when it shouldn't the dog will quickly learn to ignore it because he doesn't know what it means.
