Edit: Folks, this is a WOLF, not a dog! It is on a chain because the photo was taken at a wolf sanctuary here in the UK. I went there as part of a photography course and at one point in the day the handlers took a wolf (this one) out of the fenced areas for us to get close to. She was well-behaved but health & safety laws in this country won’t allow for wild animals that could potentially eat people to be out of “safe zones” without a chain!
