[3] After playing a handful of promising games for Williamstown, coupled with significant injury worries, the Bulldogs promoted Dahlhaus from the rookie list and named him as the substitute player in the match against St Kilda in Round 12 at Etihad Stadium.

In September Dahlhaus shaved off his iconic dreadlocks live on Before The Game for the Whitten Foundation and the Good Friday Appeal.

[12] Dahlhaus was named in the Geelong team for the 2020 AFL Grand Final played in Brisbane due to COVID restrictions in Melbourne.

The Cats led by 22 points at one stage before the Tigers - inspired by eventual Norm Smith Medallist Dustin Martin - turned the game around.

Richmond eventually took a 2-point lead into three-quarter time before running out 31-point winners to claim their third AFL premiership in four seasons.

In the Fox Sport player ratings, Dahlhaus' performance was graded as mediocre, with the exception of an industrious third quarter featuring some inside 50s and a crucial smother.
