The Canaries, who finished 12th in the table last season, are currently in the relegation zone without a win from their opening seven games.
"People did not think we would stay up last season, but we did. The more people go against this team, the better we seem to be," said Bennett.
"We will come out fighting - like a dog. If you back us into a corner, we will always bite our way out of it.
"If people keep doing that, then brilliant, because we will hopefully prove them wrong, like we did last year."
Norwich have the chance to get their first win on the board when they host Arsenal at Carrow Road on Saturday.
