A highly anticipated postage stamp collection honoring US military dogs was released Thursday. The special military working dog postage stamps showcase the canine heroes that work alongside service members and put their lives on the line to save others.
According to the USPS, the new stamp collection features four breeds—German shepherd, Labrador retriever, Dutch shepherd, and Belgian Malinois—that are commonly used as working dogs by the U.S. military. Each block of four stamps features the four dog breeds, adding up to 20 stamps per booklet.
