Foreshadowing plays a large role in indicating that Lennie isn't going to last long in this harsh world.
The fact that the death of Candy's dog and the death of Lennie are identical reflects on the way his murder was carried out. He was shot by in the back of the head the same way the dog was.

The nature scenes comment on the events in question - George and Lennie disrupt a peaceful scene in the opening; the killing of a snake by a heron prefigures the tragedy in the final chapter. Not only does this way of structuring the novel give it a feeling of wholeness, it also…
