Taken back in May so it might be a moult, we don't get many with mange as this is hunting ground and they take out most of the rough ones. I was in a green lane when I spotted a fox being chased by sheep, watched for a wile as it started to walk off thought I try calling it, came like a dream. Took a lot more shots but auto focus picked up on nettles and grass, ended up about six foot away the other side of the hedge.
