Happy to hear Forest didn't
pee . But he did run to hide behind the couch, so he's
still in fear of a reprimand and/or being yelled at. Whenever my guys do something like that, but nothing gets knocked down. I'll say something like "Hey, what are you guys doing?" in a friendly inquisitive voice. Usually, they both stop and just look at me as if to say, "Who me?"

But if
something gets knocked off a table, I'll reprimand with a stern "Bad!" and if I know who did it, and stare at the guilty one while saying it. They know when they've misbehaved.
