Through the novel we follow a dog named Buck on his journey through the Klondike. We see a transformation in him, as he adapts to the cold, harsh land where he is forced to fight in the snow, just to help men find a shiny metal. Buck seems to transform into a different dog by the end of the book. In this report, I will go over what Buck was like, how and why he was forced to adapt to his new environment, and what he changed into. When the book first met up with Buck, he lived in the Santa Clara Valley, on Judge Miller's property. He was the ruler of his domain, uncontested by any other local dogs. He was a mix between a St. Bernard and a Scotch Shepherd dog. He weighed one hundred and forty pounds, and he carried every one with utmost pride. Buck had everything he could want. Little did he know, he would soon have it all taken away from him. One night, while the judge was away at a raisin grower's committee meeting, the gardener, Manuel, took Buck away from his home. Buck was then sold, and thrown in a baggage car. This was the start of a new, cruel life for Buck. On his ride to wherever he was going, Buck's pride was damaged, if not completely wiped out by men who used tools to beat him. No matter how many times Buck tried to lunge, he would just be choked into submission at the end. When Buck arrived at his destination, there was snow everywhere, not to mention the masses of Husky and wolf dogs. Buck was thrown into a pen with a man who had a club. This is where Buck would learn one of the two most important laws that a dog could know in the Klondike. The law of club and fang is quite simple, if there is a man with a club, a dog would be better off not to challenge that man. Buck learned this law after the man who had the club beat him. No matter what he tried, he just couldn't win. Buck was sold off to a man who put him in a harness connected to many other dogs. Buck was bad at first, but eventually, he learned the way of trace and trail.
