The footage, shared by a user on Weibo, shows her pressed against a wall in a flooded street, holding on with both hands as the current drives into her, according to Hong Kong's Oriental Daily.
Her border collie cannot grip the wall and is dragged loose by the water repeatedly.
Each time the dog is pulled away, she takes one hand off the wall, reaches back and hauls it toward her.
At one point both are swept backward before she steadies them against the current.
About two minutes in, people wade in from a corner and push out a bamboo pole, pulling the woman and the dog to safety.
