Dahler joined CBS2 News on September 4, 2007 as weekend evening anchor. On May 27, 2008, the "Daily News" reported that the station had decided to give Don the co-anchorage for the 12Noon and 6:00PM newscasts, which will pair him up with veteran Dana Tyler; all of this just five days after two-time alum Jim Rosenfield was let go for the sake of budget cuts. Steve Bartelstein, whom Dahler auditioned to replace at WABC-TV after Bartelstein was fired, replaced Dahler as Mary Calvi's weekend evening co-anchor.
