I'm guessing you unintentionally personally tested it? ;))) Our garden used to be wired for an electric fence and we got rid of the main box thingy when we moved in. Now that I'm planting berries and we want fruit trees and bees as well, I think we'll have to reestablish it. It's good you have a dog that'll let you know about a bear. Big Guy never let out a peep when a bear stole my bird feeder!! He reserves barking for just people, lol.
