Newfoundlands dogs have had cameo roles in several other famous books, Charlotte Bronte introduced a Newfoundland as the companion of Mr Rochester in her classic novel 'Jane Eyre'.
The dog's name was PILOT. In the story it is decribed as: a great dog, whose black and white colour made him a distinct object against the trees - a lion like creature with long hair and a huge head.'
Bursting from the bushes Jane was at first alarmed by the dog's sudden appearance.
Later in the story she realised how faithful and docile PILOT was.
