LeDoux was born in Biloxi, Mississippi, on October 2, 1948. He was of French descent on his father's side. His father was in the US Air Force and was stationed at Keesler Air Force Base at the time of his birth. He learned to ride horses while visiting his grandparents on their Wyoming farm. At age 13, LeDoux participated in his first rodeo, and before long was winning junior rodeo competitions.
LeDoux continued to compete in rodeo events and played football through his high-school years. When his family moved to Cheyenne, Wyoming, he attended Cheyenne Central High School. After twice winning the Wyoming State Rodeo Championship bareback riding title during high school, LeDoux earned a rodeo scholarship to Casper College in Casper. During his junior year at Eastern New Mexico University, LeDoux won the Intercollegiate National bareback riding championship.


Despite offers from various record labels, LeDoux refused to sign a recording contract, instead choosing to retain his independence and control over his work while enjoying his regional following. In 1989, however, he shot to national prominence when he was mentioned in Garth Brooks' top-10 country hit "Much Too Young (To Feel This Damn Old)." Capitalizing on the sudden attention, LeDoux signed a contract with Capitol Records subsidiary Liberty Records and released his first national album, Western Underground, in 1991. His follow-up album, Whatcha Gonna Do with a Cowboy, was certified gold and reached the top 10. The title track, a duet with Brooks, became LeDoux's first and only top-10 country single, reaching number seven in 1992. In concert, he ended the song by saying, "Thanks, Garth!"


In August 2000, LeDoux was diagnosed with primary sclerosing cholangitis, which required him to receive a liver transplant. Garth Brooks volunteered to donate part of his liver, but it was incompatible. An alternative donor was located, and LeDoux received a transplant on October 7, 2000. After his recovery, he released two additional albums. In November 2004, LeDoux was diagnosed with cholangiocarcinoma, for which he underwent radiation treatment until his death.
LeDoux died of cancer on March 9, 2005, at age 56. His funeral was held on March 11.
