An old trash can trick comes to mind. The metal trash cans we no longer use today.. They were placed on a wooden frame with metal pipes for the cans to sit on and a 9 volt battery was connected from the metal pipe to a ground stake. The dogs in the alley soon learned not to use those cans. It was harmless but would be frowned upon today.
