In Of Mice and Men, is Candy lonely and is this worse after his dog is shot?Is candy isolated? find evidence in the text to support this.

Candy is somewhat lonely because his dog was his best
friend. Perhaps his main struggle, however, is his own battle with age. Candy feels as
though he is becoming useless to the farm as he grows older. The death of his dog
parallels this fear within Candy's mind. His dog was old; he was then killed. Candy's
fear of becoming useless is exacerbated after his dog's
death.

Candy's loneliness is aided somewhat by the small
hope he holds that he might be able to take part in George and Lennie's farm with the
addition of his savings.

A better example of loneliness in
the novel is Crooks, though Candy also embodies this emotion to some
extent.
