How does the dog's instinct enable it to escape the man's fate?

The dog is guided by instinct and the man is guided by a sense of arrogance. The man treats the dog as he treats nature: he lacks respect for both. The dog and the elements are in sync with nature’s rhythms: the man is not. London's familiar theme of respect for this setting is hammered home when the man freezes to death alone in the snow.The dog will survive, the dog knows the cold and what his limits are: this instinct born through ages of natural selection and conditioning.
