After graduating with a degree in accounting, Howe continued his playing career. He appeared briefly with the Pittsburgh Hornets before travelling west and spending several seasons in the Western Hockey League. Howe retired in 1964 but returned three years later as a member of the US National Team. He played at the 1967 Ice Hockey World Championships and finished tied for second in team scoring with 5 points in 7 games. The team finished 5th, a slight improvement over the previous year, but not good enough to keep Howe for another tournament.
