The oldest operating pet cemetery in the world, and the only pet cemetery listed on the National Register of Historic Places, is also the location of what’s believed to be the first memorial of its kind, a War Dog Memorial. Dedicated in 1923 to honor the military working dogs that served in conflicts, the memorial is situated at Hartsdale Pet Cemetery and is listed in the Art Inventories Catalog of the Smithsonian Institute. It was dedicated after World War I, and is the first public tribute to honor military canines for their bravery and sacrifice. A life-size German Shepherd Dog sculpture is the product of private donations collected in the afterglow of WWI, although local war dogs of all eras are welcome. Notes the caretaker: “Messenger dogs were fair game, but no one ever shot a Red Cross dog.”
