The Postal Service™ announced that a new booklet of 20 stamps will honor the nation’s military working dogs. The four breeds that commonly serve in the military (German shepherd, Labrador retriever, Belgian Malinois, and Dutch shepherd) will each be honored with a block of four stamps. The stamps will also feature a white star in the center and a background of red, white, blue, or gold to represent the American flag and patriotism.
