You’re deluding yourself if you think the dog would still obey you – unless you were able to bluff your way into retaining the role of pack alpha. The dog obeys in large part because it’s below you in the dominance hierarchy and dogs care about approval from folks higher up that chain.
I know people who have had to attend obedience classes to learn to be “more alpha” precisely because their dogs would NOT obey without stronger signals that they should do so.
Think about it this way: If you were three inches tall, your kids wouldn’t obey you either unless you could demonstrate why they should do so.
