Dunleavy is currently the play by play voice for the Buffalo Sabres on MSG Western New York and WGR 550 radio in Buffalo. From 2016 until 2022, Dunleavy rotated with Hall of Fame announcer Rick Jeanneret, who was to retire after the 2016–17 season. Rick changed his mind about retiring despite the agreement he and the Sabres signed with Dunleavy, leaving Dunleavy to work on a year by year time table with the hope of eventually taking over as was offered by the NHL franchise. To partially compensate, Dunleavy's role was also expanded to include filling in as studio host for Brian Duff when not substituting for Jeanneret.

Dan was about to call his third season of Toronto Maple Leaf radio play by play on The FAN590 and TSN1050 in the 2013-14 NHL season, when Buffalo approached him about taking over for Jeanneret. Dunleavy accepted, mainly because of his concerns about being split between the two Toronto stations, each owned by two of Canada's biggest multimedia conglomerates (Bell Media and Rogers Communications), both of whom also held ownership stakes in the Leafs.^[3] The Sabres signed Dunleavy to a five-year contract that expires in 2018; Dunleavy has turned down other offers during his time with Buffalo and remains in negotiations for a contract extension.^[4] On May 9, 2021, unsure of whether or not he would return to the Sabres, he posted a potential farewell message in the event that he did not renew his contract.^[5] The Sabres publicly stated that they were interested in renewing Dunleavy's agreement.^[6]

Since the last update, Dan has renewed once again as the voice of the Buffalo Sabres indefinitely.

From December 2004 through January 2011, Dan called the World Junior Hockey Championships on The FAN Radio Network, alongside Jack Miller. That run included five straight gold medal wins for Canada, two gold medal wins for the United States and one gold medal win for Russia.
