Following the war, Bentley returned to the Black Hawks where he was reunited with his brother Max. The brothers and Bill Mosienko formed a line in which each player was small and exceptionally fast; they were dubbed the "Pony Line" and emerged as one of the top scoring lines in the league. Max led the NHL in scoring with 61 points, while Doug scored 40 points in just 36 games for Chicago. He improved to 55 points in 1946–47 and was named a First Team All-Star for the third time. He played in the first All-Star Game on October 13, 1947, for the NHL All-Stars, who defeated the Toronto Maple Leafs, 4–3.
