COLUMBIA, Mo. – Of the 2 million United States Service members that have been in wars in Iraq and Afghanistan, it’s estimated that up to 50 percent experience combat-related issues ranging from substance abuse to Post Traumatic Stress Disorder (PTSD). Now, a University of Missouri professor is conducting a unique study that will give military veterans a “training buddy” to help them cope while helping shelter dogs become more adoptable. The Central Missouri Humane Society is supplying the dogs involved in the study. (more…)
