Who is the actor on Spiriva commercial - Tony Dow?

You are thinking of the late Tony Dow, who was known for his role as Wally Cleaver on the iconic TV show "Leave It to Beaver". While he did appear in many TV shows and movies, he is not the actor in the Spiriva commercial.

Unfortunately, I do not have access to real-time information about commercial actors. You could try searching for the commercial online (like on YouTube) and see if the actor is credited in the video description.
