In recognition of the many ways that working dogs contribute to human society, the United States Postal Service is issuing stamps featuring working dogs. This new set of four stamps illustrates some of the many important jobs that dogs do. The individuals portrayed are a guide dog, a dog who is tracking, a search and rescue dog and a therapy dog.
The “Dogs at Work” stamps  are the work of artist John M. Thompson who created the original paintings and art director Howard E. Paine, who designed them. They are 65 cent stamps, which is the postage required to send a piece of first class mail weighing between one and two ounces.
Dog stamps have historically sold well, with the “Adopt a Rescue Pet”  set selling out quickly at many post office branches. A large number of the new stamps will likely be sold to collectors as well as to those of us who like dogs and appreciate being their friends, family members and coworkers.
Any dog-loving philatelists out there?
