Dethloff, the son of Carl Curt Dethloff (1900—1977) and the former Camelia Jordan (1907—2000), grew up in Natchitoches, an historic city in north central Louisiana. His brother was Carl Richard "Dick" Dethloff (1929—2007), a graduate of Kansas State University in Manhattan who became a prominent insurance agent in Shreveport. Dethloff also has a sister, Cammie D. Girand.

He received his Bachelor of Arts degree from the University of Texas at Austin in 1956, his Master of Arts from Northwestern State University in Natchitoches in 1960, and his Ph.D. from the University of Missouri in Columbia in 1964. He joined the TAMU faculty in 1969 and served as the department chairman from 1980 to 1985.
