I was traveling for my job last week and could not participate in Sunday Stamps. Back again this week however, and happy to share stamps on the theme of the week, which is canines. Our hostess has shared some wolves. I have some stamps recently issued by the US Postal Service, of military dogs. There is a set of 4, and one is featured on their web page and copied here:on the stamps are German Shepherd, Labrador Retriever, Belgian Malinois, and Dutch Shepherd. The images are by Greg Breeding. Less dogs are used now than in the past by the military.
