In answer to the thread, "how much" depends on the size / breed of the dog and also their age. Little dogs don't need a lot (but should definitely still be out at least twice a day), larger and more energetic dogs need a lot more. Old dogs might not want to go very far at all and it can be cruel to force them as they can be in pain / get very tired.

Also depends how much "free time" they get outdoors and how much space you have. A dog that has a (large) garden or a field to run around freely in doesn't need walks further afield as much (but should still get to explore plenty, it's not an excuse to never take them). Dogs cooped up with no garden at all need out several times a day. IMO you shouldn't keep a dog at all in those circumstances, though.
