The Bulldogs went into the final on the back of some poor performances but that certainly didn’t affect them, they were on top of the Canberra Raiders the entire match. Even in the miserable conditions it didn’t affect them. The Bulldogs did what they do best stuck together and ripped in. The Bulldogs got the luxury of having a week off the following week. In the preliminary final against the Brisbane Broncos the Bulldogs showed some specular plays and tries in the first half and ended up winning the first half 20-6, but cannot say to much about the second half performance from the Bulldogs. The Bulldogs went down to the Broncos 37-20
