When Tony Tengwall returned from deployment in Baghdad with the Minnesota Army National Guard in 2005, he struggled to readjust to civilian life.
Tengwall got a job and went back to school, but it was "tougher than it should have been," he said. He was losing touch with family and friends. He didn't socialize.
It wasn't until he started working with other veterans that he noticed similar traits: anxiety, frustration.
"It helped me understand that there are things not working here," he said. It was post-traumatic stress disorder.
A colleague, who also works with veterans, saw how Tengwall would interact with one of her foster dogs, Fitz. The 4-year-old English cocker spaniel would calm Tengwall and "brought him to the present," said Lauri Brooke, a county veterans service officer in Becker County.
"Fitz had the ability to immediately calm Tony down," Brooke said. "It was really amazing."
Fitz is a psychiatric service dog who has helped Tengwall, 35, a veterans service officer in Anoka County, with his PTSD. The pup, who also goes to work with Tengwall, provides the same comfort to other veterans when they visit the office.
"I haven't had an angry vet since I got Fitz," he said. "They come in, sometimes angry, sit down and start petting him. And then their mood completely changes."
