In this photo taken on Monday, Nov. 2, 2015, Dr. Rob Garofalo pets his
dog, Fred, at their home in Chicago. Garofalo, who is head of the
adolescent medicine division at Lurie Children's Hospital of Chicago,
tested positive for the AIDS virus in 2010.
He fell into a deep
depression and was thankful to Fred, a Yorkshire terrier, for bringing him back
to life. Garofalo has since co-founded the "When Dogs Heal" photo
project, which features HIV-positive people and their dogs. The exhibit
opens in Chicago on Dec. 1, which is World AIDS Day, and in New York
City on Dec. 3.
