Nice, but....I’m going to say something breedist.
Standard Breeds of U.S. MWDs Today
The vast majority of U.S. military working dogs in recent times are German and Dutch shepherds and Belgian Malinois, breeds chosen because they are very aggressive, smart, loyal and athletic.
German Shepherd dogs are preferred as the standard breed because of their unique combination of traits. Shepherds are intelligent, dependable, predictable, easily trained, usually moderately aggressive, and can adapt readily to almost any climatic conditions. While many dog breeds exhibit some or most of these traits, the Shepherd more than any other breed, most consistently exhibits all of these traits.
For specialized roles, detector dogs in particular, other breeds are used. Retrievers (Labrador, Golden or Chesapeake Bay) are the preferred breeds for One Odor Detector dogs.
All dogs trained and used by the U.S. military are procured and trained by the 341st Military Working Dog Training Squadron, Lackland AFB, TX.
