[ London / Call of the Wild ]
This famous work features several references to Newfoundland dogs. The first occurs in Chapter 1 of the novel (which is told from the perspective of Buck, the lead dog):
Buck saw money pass between them, and was not surprised when Curly, a good-natured Newfoundland, and he were led away by the little weazened man. That was the last he saw of the man in the red sweater, and as Curly and he looked at receding Seattle from the deck of the Narwhal, it was the last he saw of the warm Southland.
(Curly the Newfoundland is killed by other dogs early in Chapter 2 of this novel.)
The second reference is in connection with the assembling of a sled-dog team:
Charles and Hal went out in the evening and bought six Outside dogs. These, added to the six of the original team, and Teek and Koona, the huskies obtained at the Rink Rapids on the record trip, brought the team up to fourteen. But the Outside dogs, though practically broken in since their landing, did not amount to much. Three were short-haired pointers, one was a Newfoundland, and the other two were mongrels of indeterminate breed. They did not seem to know anything, these newcomers.
The last occurs when the sled dogs slowly die off due to malnutrition and brutal treatment:
It is a saying of the country that an Outside dog starves to death on the ration of the husky, so the six Outside dogs under Buck could do no less than die on half the ration of the husky. The Newfoundland went first, followed by the three short-haired pointers, the two mongrels hanging more grittily on to life, but going in the end.
