The dog on 'Doc Martin'
I just started watching the first episode of Doc Martin (thanks to the fans at the KT), and saw a dog that looks exactly like Angel, our family's late companion. My daughter Jill found Angel as a puppy, looking abandoned on a road. We had no idea what she was, but a Briard breeder identified her as a Briard. She certainly had all the personality characteristics of a Briard, too, but lived much longer (16 years) than the breed's average (11-12 years). I figured she was a Briard with some hybrid vigor.
I Googled Doc Martin Dog and found discussions of the possible breed. I looked the suggested breeds up, but none of them look as much like the dog in the show as Angel did. Does this dog remain on the show through the various seasons?
