Both clubs were promoted from the Championship after last season and have been revelations this year and Pulis said that clubs would have to be wary.
"We play Hull next week and they have really been the flag-bearers for the Championship in the Premier League this season," said Pulis.
"The top four clubs will eventually pull away but for the rest of us, the closer we are together the better. It certainly suits teams who are fighting for points every week.
"Yes, there are games you can look at and say 'we're going to specifically target those games' but, especially at the Britannia, if we are on it and the crowd are up for it and everything is going the way we want it to, we have every chance."
