Book excerpt: “Forever Forward” is the first in-depth account of K-9 Operations during the Vietnam War, and provides a behind the scenes look at how Allied forces employed dog teams in a variety of roles, the evolution of the United States military working dog program, and the aftermath of Vietnam. The 4,000 dogs that served with our men in Vietnam in every service branch are America’s unsung heroes. American dog teams averted over 10,000 casualties and worked as scouts, sentries, trackers, mine, and tunnel detectors. They were so effective the Viet Cong even placed a bounty on them. Heroes yes, but our own government left most of them behind to an unknown fate.
