The video, posted on Facebook, was viewed more than a million times.
Among those viewers? Jen Deane, who runs animal welfare group Pit Sisters, sees Angels every day.
"I saw the video and immediately called about getting her rescued," Deane told The Dodo.
But had the world already sunk Angel? Was she beyond saving? When it comes to screening dogs, the group often relies on a canine aggression expert. When that expert paid Angel a visit at the shelter, she, well, exhibited very much the opposite of canine aggression.
