What is the author's style in A Boy and His Dog by Harlan Ellison?

Almost immediately, Ellison demonstrates Vic and Blood's severe language and attitudes. These characteristics are consistent throughout the story, reflecting their reaction to the hopeless world in which they live. They are products of their environment, so they speak with profanity and relate to each other harshly. Distrust is central to their world, which is evident in the way the characters interact with one another.
