How are Candy and his dog alike?

There is a lot of symbolism in this novella. Candy is old and his dog is old. They have spent many years together and have aged together. Loneliness permeates this ranch and these two, much like Lennie and George, have each other. Candy and his dog have also outlived their use. Candy’s only consolation is that he is a man and would not be disposed in the same way as his dog but, in the end, he would be told to move on.
