Sebastian Vettel, who has an 83-point championship lead, and team-mate Mark Webber together called for a re-think.
But Red Bull team boss Christian Horner told BBC Sport: "We work as a team and the drivers don't need to tell the team we need to react.
"Ferrari and McLaren are going through a spirited phase but we're still right there. We're pushing flat out."
Vettel stormed to conquest in six out of the first eight races but his progress has been slowed as Ferrari and McLaren have enhanced their pace in the races to close the gap on Red Bull.
Fernando Alonso won in Britain for Ferrari, with McLaren drivers Lewis Hamilton and Jenson Button taking a conquest apiece in Germany and Hungary.
While it appears that Red Bull's period of dominance is over, Horner does not believe that the tide has turned against the champion team.
"We don't look at it like that," said Horner. "We need to keep doing the best job we can and keep getting developments to the car.
"If you look at all the races this year, I don't think there is any race that we've run away and immensely dominated.
