The article discusses the traditional view in classical dressage that a double bridle signifies a fully trained horse and rider, a notion rooted in military practices from 300 years ago. Historically, bits have been used since ancient times, with severe training methods evolving into kinder classical techniques during the Renaissance. Early dressage often began with snaffle bits, and bitless bridles have long existed as alternatives. While a well-fitted double bridle used sensitively is not inherently harmful, misuse can cause significant discomfort and welfare issues, as evidenced by images of horses with blue tongues from excessive pressure.

A significant change occurred in 2019 when the Fédération Équestre Internationale (FEI) allowed riders in certain international competitions and youth classes to choose between a double bridle and a simple snaffle bridle. This shift marked a historic move towards prioritizing horse welfare, promoting softness, and fostering a genuine connection between horse and rider, breaking from the long-standing tradition that favored the double bridle as the standard of advanced training.
