Reports on Wednesday morning suggested that Dawson was unhappy at the Spurs' refusal to offer him an improved deal, but he insists he is completely happy at the club.
The 27-year-old, who was made captain halfway through the 2009-10 season, says he is not looking for a new contract and is content with the terms of his current deal.
"I have no idea where this story has come from - it certainly has not come from myself or any of my representatives," Dawson said.
"I think I have always demonstrated that I am a proud player and captain of this club and nothing has changed in that respect.
"I have an excellent relationship with everyone at this club from the chairman, to the players to the supporters and I wouldn't want false reporting such as this to impact on that.
"There has been absolutely no fallout with anyone whatsoever. I still have four years left on my current contract and have no issues regarding it whatsoever. It is an honour to be captain of this football club and my sole focus is on getting ready for the new season with Spurs and, hopefully, England as well."
