Yes absolutely and completely.

Here’s what would actually happen if this fictional scenario did occur:

If someone hands me something to consume, no matter how much I trust them, I would ask “cool thanks, what’s in the sandwich?”

Now you, a non-deceiver, would say “peanut butter and pharmaceuticals”. And I would say “oh, I’m not sure I want that, but thanks for being honest”

I hope you see how this analogy does not map to dogs.

You have avoided answering by changing the scenario. Deception was implied. I'll take that as my assumption being correct and you were simply too proud to admit it.
