Whyn’t you get Candy to shoot his old dog and give him one of the pups to raise up? I can smell that dog a mile away. Got no teeth, damn near blind, can’t eat. Candy feeds him milk. He can’t chew nothing else.

– John Steinbeck

Of Mice and Men, Chapter 2. Carlson to Slim. Carlson is quick to suggest putting down Candy’s dog because it is old and decrepit.
