Sir Arthur Conan Doyle / "The Adventure of the Creeping Man" ]
The dog featured in this story is a wolfhound; at one point it breaks free from its restraint and attacks its owner, and we get the story's only (indirect) reference to Newfoundlands:
And then in a moment it happened! It was not the chain that broke, but it was the collar that slipped, for it had been made for a thick-necked Newfoundland.
