Bayern have a 100% record so far in the Bundesliga, winning all of their seven league games this season.
Dortmund already trail their title rivals by nine points, but Klopp thinks that the gap is far from decisive at this early stage of the season.
He said: "We play our own season and only twice against Bayern Munich.
"These games are very interesting, but they are not the final result, not after seven games."
That point leaves the reigning champions in fifth place in the Bundesliga on 12 points, four places behind pacesetters Bayern.
