The U.S. Postal Service this week unveiled new stamps to be released this year in honor of military working dogs. The four designs feature a German shepherd, Labrador retriever, Belgian Malinois and Dutch shepherd.

"The stylized digital illustrations are in red, white, blue and gold to represent the American flag and patriotism," the Postal Service said in a release.

The background of each stamp features a white star that appears in the center of each block, the release said.
