METHOD #1. leave something yummy like a slice of pizza on the
counter within EASY reach of the dog. Tie a string through it and
leave about 2 feet of string between the pizza and a series of
aluminium cans with pebbles in them. Dog snatches pizza, tries to run
off with it and is chased by the cans. Evil counter! You of course
had nothing to do with this (at least pretend that you didn't).
METHOD #2. leave pizza within reach. Surround slice with a
few old fashion mousetraps covered with aluminium foil. You could
even attach the traps to the pizza with thread or string. The foil
protects the dog from actually getting a toe caught, and also
becomes a flying thing when the trap is bumped and goes off. Most of
them snap and flip in the air so that sends the foil flying as well.
Again you maintain your innocence in this event from your armchair
in the other room.
