In the book Of Mice and Men by John Steinbeck, what do other characters think or say about Candy?

From the text:

Carlson said thoughtfully, “Well, looka here, Slim. I been thinkin’. That dog of Candy’s is so God damn old he can’t hardly walk. Stinks like hell, too. Ever’ time he comes into the bunk house I can smell him for two, three days. Why’n’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.”

“All but old Candy. He just sets in the bunk house sharpening his pencil and
sharpening and figuring.”
Crooks adjusted his glasses. “Figuring? What’s Candy figuring about?”
Lennie almost shouted, “’Bout the rabbits.”

She stood still in the doorway, smiling a little at them, rubbing the nails of one hand with the thumb and forefinger of the other. And her eyes traveled from one face to another. “They left all the weak ones here,” she said finally.

Curley’s wife laughed at him. “Baloney,” she said. “I seen too many you guys. If you had two bits in the worl’, why you’d be in gettin’ two shots of corn with it and suckin’ the bottom of the glass. I know you guys.”
