ending- Lennie killedMice and men, how does ending relate to candy and his dog earlier in the book?
Both Lennie and Candy's dog would suffer if they lived. Candy's dog wasn't in good health and Lennie killed Curly's wife and would be in trouble with the law. Candy lets Carlson kill his dog, but regrets it later because he would have rather killed the dog because of he was his only friend. The same goes with George and Lennie except that George kills Lennie.





The last paragraph of Spark Note's theme page of the Of Mice and Men page titled ';Candy's Dog'; explains it in better detail.Mice and men, how does ending relate to candy and his dog earlier in the book?
Candy let someone else kill his dog for him and it is like a premonition for when George kills lennie. But, George learns from Candy's mistake (he wanted to take responsibility for his dog and kill himself) that he must be the one to kill Lennie to stop him from being dangerous not only to the people around him, but to himself. He was suffering alive and it was kinder to put him down, just like it was kinder to put Candys old dog down.


I'm doing this at the moment in GCSE and remember: Quote!
Because Candy had to put down his dog because it was so old and slowly dieing. He had to put it out of his misery. In the end, that's what George did for Lennie- Lennie just kept getting in trouble and after he killed that girl in the barn George knew that Lennie would be imprisoned and eventually killed- he was watching out for Lennie and put him out of his misery before someone could torture him.
