A dog in Turgenev's Yermolai and the Miller's Wife.
"...a setter-dog, by name Valetka, a most extraordinary creature. Yermolai never fed him. 'Me feed a dog!' he reasoned; 'why, a dog's a clever beast; he finds a living for himself.' And certainly, though Valetka's extreme thinness was a shock even to an indifferent observer, he still lived and had a long life; and in spite of his pitiable position he was not even once lost, and never showed an inclination to desert his master. Once indeed, in his youth, he had absented himself for two days, on courting bent, but this folly was soon over with him. Valetka's most noticeable peculiarity was his impenetrable indifference to everything in the world.... If it were not a dog I was speaking of, I should have called him 'disillusioned.' He usually sat with his cropped tail curled up under him, scowling and twitching at times, and he never smiled. (It is well known that dogs can smile, and smile very sweetly.) He was exceedingly ugly; and the idle house-serfs never lost an opportunity of jeering cruelly at his appearance; but all these jeers, and even blows, Valetka bore with astonishing indifference. He was a source of special delight to the cooks, who would all leave their work at once and give him chase with shouts and abuse, whenever, through a weakness not confined to dogs, he thrust his hungry nose through the half-open door of the kitchen, tempting with its warmth and appetising smells. He distinguished himself by untiring energy in the chase, and had a good scent; but if he chanced to overtake a slightly wounded hare, he devoured it with relish to the last bone, somewhere in the cool shade under the green bushes, at a respectful distance from Yermolai, who was abusing him in every known and unknown dialect."
