Bowyer is 34 next week but continues to play a key part for Blues and followed his winner against Chelsea with a last-gasp equaliser against Manchester United on Tuesday evening.
The former England player is out of contract next summer and Blues boss Alex McLeish is reluctant to make any public comment on Bowyer's long-term future. But central defender Dann feels Bowyer is still up to the task of performing in the Barclays Premier League.
Dann told Press Association Sport: "That sort of goal he scored against Manchester United is typical Lee Bowyer for you. He did it last season as well, scored some important goals, and was one of our top goalscorers.
"He earned us a lot of important points last season. That is what you get from him. He makes those good runs into the danger area and he has got a good goal tally."
Dann added: "Can he play for another couple of years? He is still very fit and still loves the game. If he carries on putting in performances like that, then there is no reason why he can't carry on for a couple of years."
