Your dog can’t complain about the walk you skipped. That’s exactly why you shouldn’t skip it.

Something that cannot speak for itself depends entirely on whether you care when nobody is checking. No complaint is coming, no consequence, no record anywhere. That is what makes it a clean read on you rather than on your circumstances. Whatever you do for a creature that cannot argue back is done purely for your own reasons.

Do the walk today, even the short version. Then look at what else around you cannot complain: a plant, a younger sibling, a friend who never asks for anything. Those are the places worth checking first.
