The well-meaning people who picked up an injured dog took her to a dog-rescue centre. When the centre realized they were dealing with a fox, they brought her to the Nuneaton & Warwickshire Wildlife Sanctuary.
By that time, she was too habituated to humans to survive in the wild. She will live the rest of her life with the sanctuary’s other resident foxes. From the looks of this video, she will have a good life.
