The can method works great, it was told to me by my vet. YOu take an empty aluminum can and fillit up with pennies and tape up the top. Whenever you catch the dog in the action, shake the can and say no. Or if you find the accident, being the dog to it and put their nose by it shake the can and say no. This mehtos works great and fast. They hate the sound and do not wish to hear it. I also had a friend that was able to use this method to keep her 2 labs from climbing the kitchen counters. Hope that helps.
