The US Postal Service is issuing a new set of stamps that are sure to please dog lovers.
The four new stamps feature military working dogs.
The Forever Stamps depict four breeds commonly used in the armed forces: the German Shepherd, Labrador Retriever, Belgian Malinois, and Dutch Shepherd.
Dogs have served in the US military since World War I.
Their heightened sense of smell and convenient size make them suitable to a variety of tasks, including search and rescue.
There are currently an estimated 2,300 working dogs on US bases worldwide.
A memorial in New Jersey honors all dogs that have served in the military.
