She stopped at the empty house on Division Street after noting "suspicious activity" outside, according to the Baltimore Police Department's Facebook post.
Inside the house, she found a gray and white terrier mix suffering in silence, his owners having abandoned him.
"He was actually groomed pretty well. He didn't show any signs of aggression," Acord told the Baltimore Sun. "He just seemed like he wanted attention."
It was just a short drive to the nearby Baltimore Animal Rescue and Care Shelter, but Acord told the newspaper she and the dog bonded instantly.
Upon dropping him off there, she immediately filled in the paperwork to adopt him.
Three days later, and without a word from his previous owners, Acord took the dog, whom she named Grayson, home.
