From your link:

The concept of dual nationality means that a person is a citizen of two countries at the same time.

In my opinion that means that someone with dual nationality can't be "Natural Born".

My father had dual citizenship at birth; US and Canadian. He made a point of telling me that he couldn't be POTUS. I may not even be eligible by some of the stricter interpretations I've seen here. I also wouldn't want to be. I am not qualified although if thrust into the role I would do my best.

I don’t see why native born children of citizens would not qualify as natural born.

Born in the US and both parents citizens, even if dual? Then you are eligible.

“My father had dual citizenship at birth; US and Canadian. He made a point of telling me that he couldn’t be POTUS.”

If your father was born on US soil, your father was wrong. If he was a citizen at birth, he was a natural-born citizen. Dual citizenship does not preclude eligibility to be President.
