During World War II, Dugan served in the United States Army Air Corps,[4] from January 1943 to January 1946.[6] He was first stationed in Miami Beach, Florida, where he played football and baseball.[4] He was then transferred to Las Vegas Army Air Field, where he coached the air field's baseball team, the Horned Frogs.[4] They competed against other military teams, and also won some semi-professional tournaments.[4]
While in the military, Dugan had surgery to remove warts on his feet; this led to an infection, and caused him to walk with a limp for the rest of his life.[4]
After the war, Dugan returned to the University of Kansas,[4] where he served as head coach of the baseball team in 1946.[7] The team had a record of 4–6, playing all of their games within the Big Six Conference, and finishing in fifth place in the conference.[8] Dugan earned a degree in physical education and became a teacher.[4] He later worked in Hiawatha, Kansas, for 30 years as a coach and teacher.[4] He also served in the Kansas National Guard until 1968.[2]
Dugan died in Hiawatha in 1992.[4] He was a widower, and was survived by a daughter.[2]
