March 13, 1942 is the official birthday of the United States K9 Corps. They served to save, and they deserve to be remembered. Photo caption: In a forgotten plot called Happy Hunting Grounds in South Lyon, MI, there is an old pet cemetery that also is home to fallen canine veterans. We honor not only those in the K9 Corps, but also Police K9s, Customs K9s, Border Patrol K9s, Secret Service K9s, Airport Police K9s, F.B.I. K9s, and other working dogs that protect us every day.
