A part of the Quartermaster Corps, the U.S. Army Remount Service provided horses (and later mules and dogs) as remounts to U.S. Army units. Evolving from both the Remount Service of the Quartermaster Corps and a general horse-breeding program under the control of the Department of Agriculture, the Remount Service began systematically breeding horses for the United States Cavalry in 1918. It remained in operation until 1948, when all animal-breeding programs returned to Department of Agriculture control.
