Wet conditions began to impact the state of play but both teams battled hard to gain possession and move the ball into their attacking half.
Dahlhaus, Dickson and Johannisen added majors throughout the quarter for the Bulldogs, while stalwarts Picken, Boyd and Murphy were solid in their roles.
Richmond were able to claw back the margin with two red time goals, but the Bulldogs still ended the break leading by one point.
One to watch
Rookie defender Brett Goodes looked composed playing off half back, keeping his opponent accountable as well as being reliable with ball in hand.
Final score
Western Bulldogs 10. 8. 68 leads Richmond 10. 7. 67
