Quite simply, Candy loves the very old dog which he had kept since the dog was a pup. Candy's dog is his companion, having kept him company and given him affection for many years. When Carlson first suggested that it was time to shoot his dog, Candy replied softly, "No . . . No, I couldn' do that. I had 'im too long." Carlson persists. Candy resists, trying to come up with an argument to stop Carlson: "Maybe it'd hurt him . . . I don't mind takin' care of him." During the discussion, Candy is afraid of what's coming. Carlson presses the point. When Slim won't intercede on Candy's behalf, Candy gives up and gives in. Carlson takes the dog outside, and after a time, a single shot is heard. Lying on his bunk, staring at the ceiling, Candy then turns over and faces the wall. He loved his dog and is now alone without him.
because candy has had him since it was a puppy, and if he gets rid of it then he would be loney
