the theme is transformation because the old buck-the civilized, moral buck-must adjust to the harsher reality of life in the cold north where he needs to survive.
ways he has transformed:
One way is that he lost his pride from commander to a obedient dog.
```````````````````
he is limited to his normal supply of food and water.
```````````````````
He has to survive by his own in the Klondike
```````````````````
Manuel, took Buck away from his home.
```````````````````
Buck was sold, and thrown into a baggage car.
```````````````````
When Buck arrived at his destination he was thrown into a pen with a man who had a club. He was beaten until he understood that the man with the club was to be obeyed.
```````````````````
he was later sold off to a man who put him on a sled team in a harness connected to many other dogs.
```````````````````
Buck was found it hard to adapt to this at first, but eventually, he learned the way of trace and trail.
