Nigel Pearson's side lost three of their first five league matches this season but have steadied the ship in their last two outings, while they have yet to leak a goal at the KC Stadium.
Dawson said: "It's four games at home and no goals conceded and we've got to keep this form at home going.
"We're happy with it. Now we've got two away games coming up and we've got to look forward to those now.
"After the defeat at Cardiff, you would probably take four points from the two games. More than that, the performances have been there as well so we have something to build on now."
