Yesterday read the book "The Call of the Wild", there are not many pages, if you read the book quickly, it is estimated that it will take more than an hour to read it, but I spent three days before and after.
Then it touched me, the protagonist of the book is a dog, named Buck, it is a combination of St. Bernard and shepherd dog offspring, Buck was originally in the home of a justice, living a well-bred life, but one day, by the judge's family for lack of money, sold to the dog seller.

Then its life changed dramatically, first from the warm south, to the cold north, and then at first it was still very untamed, and soon under the big stick of the dog seller, it understood that the big stick and fangs were the survival rules of the law.
Although it has its own temper, it also has an innate ability to recognize, and it will not be like some dogs, because it has always refused to give in, and eventually it will be killed.
Buck was then sold as a sled dog delivering mail, and began a career that was very different from before. The sled is pulled by several dogs, and there must be a platoon leader and an ape driver.
Buck started in the middle, it was very learning, and soon it learned how to go sledding. At the same time, it also found that the position of the platoon dog was what it wanted, and the platoon dog was what it hated, but Buck was very clever, and when he was weak at first, he tried to avoid conflicts with the platoon dog.
Some dogs stole its food, and it quickly followed suit to steal food from other dogs. It is also very cunning, occasionally stealing its owner's food and blaming other dogs.
After a period of time, Buck has begun to adapt to the life of pulling sleds, he is no longer afraid of the platoon dog, so when the platoon dog goes to teach other dogs, it will come out to block, and then often take advantage of the owner's unpreparedness, deliberately provoke the other dogs in the group to disagree with the platoon dog, isolating the platoon dog.
Finally, in the process of chasing a hare, the conflict between Buck and the platoon dog broke out, and when he could not directly bite the opponent's neck, Buck used his own mental analysis to take the method of biting off the opponent's dog leg in parts, so that the opponent completely lost the ability to resist and became the hyena's dinner.
So Buck justifiably became the vanguard dog, and he quickly straightened out the morale of the army, adjusted the morale of the team, and set a record for the speed of delivering mail, but because it needed to be repaired, and the mail could not wait, they could not leave immediately, and they were resold to two other people who were ready to go to pan for gold.
This time, their disaster began.
