A lady I babysat for yearrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrs ago had a puppy that was suppose to let you know whenever he needed to go outside which I thought was wonderful but then one day before she had a chance to leave we heard a yelp and then nothing. Went into the living room and found that the dog had peed towards a light socket. Apparently when the stream hit the socket, the electricity traveled back up the stream. The dog was found under the bed and wouldn't come out.
