when my puppy did something naughty, like chewing my favorite shoes, mommy and daddy said we need a "proposal" to teach him good manners, but he sometimes "refuse to acknowledge" us when we say "no". we learned about "preexportation" check-ups to make sure he's healthy before we can visit grandma's house because dogs without them are "banned" from flying. i think it's like a game where we all "relaunch from zero" when he forgets the rules, and we try teaching him again with extra hugs and treats.
