Near the begininng of the story, Landon describes the setting as, "There was no promise of sun, although ... not a cloud in the sky" (Landon 64). Landon is critizing the bad weather the man is facing, while foreshadowing the setbacks he will face in the future.
Listen to your elders
As the story progresses, the man doesn't care about the weather and is unprepared for his trip. Yet he continues to go along without stopping. Landon describes, "It was 75 below zero" (Landon 66). He seems to have a bad interaction with his dog. We see his spirit continue on till the man strugggles to survive in the end of the story.
A good judgement and people are essntial for travel.
In any cold environment, fire is the best tool to have. The title mentions this and how it is referenced in the story, suggesting that this could be a potential main idea. As the fire eventually dies down, his body and the dog start to feel the cold again.
The man is unprepared
Berfore his trip, the old men of Yukon told him specificlly not to travel alone and not to avoid travelling in the cold. The man insults them. While on the trip, the man regrets his decission and believes advice from anyone should not be forgotten and ignored with the mans's example.
To start off, the man and the dog have a bad relationship shown by thier actions and their lack of affection to each other. Landon is showing the man to have little no none affection by the tone he calls her. The dog doesn't seem to be affectionate, when it runs from him and when the man didn't warn him of the cold. Animals don't understand temperature, so the dog is trusting the man knows what he is doing. Clearly this is not true.
The manonllys takes basic gear like mittens, ear coverings, warm moccasins, and thick socks. His only other supplies are his loyal dog and his lunch. If he had more supplies and a better judgement, he would have made it. Landon and the old men put more emphasis of being prepared.
