DENVER - A Colorado researcher is looking at how important man's best friend is to veterans returning home from duty.
Sgt. Angela Miller joined the Army National Guard at only 17-years-old, but now, 20 years later, she says memories of war are never far away.
"I have nightmares," said Miller.
The Colorado native was deployed to Iraq in 2003 and says it never occurred to her what 14 months overseas working as a medic would do to her mental health. Two service dogs named Bonnie and Clyde helped Sgt. Miller manage her PTSD.
"[Bonnie] will do what's called pressure therapy and she actually gets completely in my lap," said Miller.
