A Pennsylvania program called Dog T.A.G.S. is helping veterans suffering from PTSD train their own pets as service animals to help them feel more at ease navigating crowds and being out in public. The acronym stands for Train, Assist, Guide and Serve, and the dogs, ranging from poodles to springer spaniels, each wear a service vest made out of the camouflage fatigues of its veteran owner. Kim Maugans and other volunteers started Dog T.A.G.S. in 2012, realizing that most veterans wouldn’t be able to pay thousands of dollars for a specially trained service dog. It takes a special animal to help some veterans heal.
