After Carlson kills Candy's dog, he overhears Lennie to Crooks about his dream with George to have a farm of their own. Candy mentions how he fears being fired because he only has one good arm. He also is still upset about the way his dog was killed simply because it was "no good" anymore. Candy does not want what happened to his dog to happen to him. He also has $300 he received after his hand was cut off. So, seeing an opportunity to get off the ranch and be somewhat independent, he offers the money to Lennie and George in exchange for a permanent place to stay. Suddenly, George and Lennie's dream becomes a possibility because they now see how they can afford to buy a farm.
