A year after the release of his first novel, a fan asked why there was no national monument for military dogs. So in 2004, Burnham and two other veterans pursued the idea. The trio established the John Burnham Monument Foundation Inc.
However, the plan did not become a possibility until 2006, when Burnham met North Carolina representative Walter B. Jones. In 2007, Jones introduced a bill for the construction of the monument, which was unanimously passed by congress and subsequently signed by President Bush and later amended by current President Barack Obama.
