Star and Storm suddenly began pulling said dog walkers. This was out of character for the dogs, and the walkers, bless them, went along with it. They ended up nearly a mile away, on a low traffic road, to find a woman had lost control coming off an embankment and crashed. The dog walkers were able to call emergency services for help, and the woman was taken to the hospital, though the article I linked does say there were no serious injuries.
So, Dobermans in England are quite the Good Samaritans, aren't they? Remember a year and a half ago, when a Doberman puppy alerted people on the beach to a struggling swimmer? Good stuff. And people wonder why I love the breed so much!
