Disclaimer: Foxes are wild animals and should never be approached as domesticated pets, despite the benevolent disposition of the fox in the video above.
According to the youtube video author, Dawn is one of six resident foxes at the Nuneaton and Warwickshire Wildlife Sanctuary, that cannot be returned to wildlife. Apparently, when she was still too young Dawn was mistaken for a dog and taken to a rescue shelter, consequently rendering her unable to independently survive in the wild. That might explain why she acts so much like a dog. We'll have to agree with the woman behind the camera: SHE IS SOO CUTE!
