The Purple Dog Tag is intended to provide a simple, visual signal of the wearer's support. Inspired by the classic shape of a military dog tag and colored purple to honor our wounded, the Purple Dog Tag also has a jagged hole or notch along one side. The notch is symbolic of the wounds, disabilities and handicaps - physical and psychological - that our returning soldiers are fighting very personal battles to overcome. It is the hole in their lives that our support can help fill.
