In this Nov. 13, 2014 photo, staff and volunteers from ‚Mane in Heaven‘ escort Lunar, one of two miniature horses into an elevator during a visit to patients in the pediatric unit at Rush University Medical Center in Chicago. Mystery and Lunar, small as big dogs, are equines on a medical mission, to offer comfort care and distraction therapy for ailing patients. It is a role often taken on by dogs in health-care settings _ animal therapy, according to studies and anecdotal reports, may benefit health, perhaps even speeding healing and recovery. (AP Photo/M.
