Osceola and Renegade
The Osceola and Renegade mascots were conceived by Bill Durham, a Tallahassee businessman and Florida State alumnus. He came up with the concept of a horseback-riding Seminole mascot as early as 1962, when he was voted into the school's homecoming court. He returned to the idea in 1977, and won the support of Ann Bowden, wife of head football coach Bobby Bowden, who helped make the idea a reality. Durham contacted the Seminole Tribe of Florida about the project, and chairman Howard Tommie had tribe members make the first costume for Osceola. Durham provided the horse, while Bowden helped acquire the various permits necessary to allow a horse onto the field.
University of Georgia
Uga the Bulldog is the official live mascot of the Georgia Bulldogs. Uga is from a line owned by Frank W. (Sonny) Seiler of Savannah, Georgia since 1956. The current line began with Uga I, a solid white English Bulldog who was the grandson of a former Georgia mascot who made the trip to the 1943 Rose Bowl. Perhaps the most famous Uga was Uga V who made appearances in the movie "Midnight in the Garden of Good and Evil." Uga V was also featured on the cover of the April 1997 edition of Sports Illustrated. Uga X became the mascot in 2015. Of course, although the University of Georgia is now known as the home of Uga, several mascots including other pure white English bulldogs led the Red and Black before Frank Seiler provided the current lineage.
