Military dogs see extensive use on the modern battlefield, especially with special operations. The concept goes back to Roman times where legionnaires fielded heavy Mastiffs with armored collars to attack an enemy’s legs and force them to lower their shields. In WWII, the United States Marine Corps decided to experiment with the use of dogs in the Pacific.
The Marine Corps University attributes the idea of using dogs in jungle warfare to a Marine Officer serving as a Garde d’Haiti in the 1920s. He trained a dog to work on his patrols to expose bandit ambushes. By 1935, the Smalls Wars Operation doctrine published by the Marine Corps Schools noted, “Dogs on Reconnaissance, – – Dogs have been employed to indicate the presence of a hidden enemy, particularly ambushes.” The concept was revived in 1942.
