The utilization of dogs as a supplementary force in military operations evolved during World War II. Initially, the United States Army hadn't fully recognized the potential of employing dogs, but it was the breeders and trainers who advocated for their valuable contributions to the war effort.
With the US joining the war, a shift in perspective occurred regarding the dogs' capabilities in detecting and neutralizing threats, prompting the establishment of dedicated training centers for this purpose.
