Snarleyyow by Frederick Marryat

Mr Vanslyperken is in his cabin, with Snarleyyow at his side, sitting upon his haunches, and looking in his master's face, which wears an air of anxiety and discomfiture; the fact is, that Mr Vanslyperken is anything but content; he is angry with the widow, with the ship's company, with the dog, and with himself; but his anger towards the dog is softened, for he feels that, if anything in this world loves him, it is the dog -- not that his affection is great, but as much as the dog's nature will permit; and, at all events, if the animal's attachment to him is not very strong, still he is certain that Snarleyyow hates everybody else. It is astonishing how powerful is the feeling that is derived from habit and association. Now that the life of his cur was demanded by one, and, as he was aware, was sought for by many, Vanslyperken put a value upon him that was extraordinary.

Snarleyyow had become a precious jewel in the eyes of his master, and what he suffered in anxiety and disappointment from the perverse disposition of the animal, only endeared him the more. "Yes, my poor dog," apostrophised the lieutenant, "they would seek your life -- nay, that hard-hearted woman demands that you should be laid -- dead at her porch. All conspire against you, but be not afraid, my dog, your master will protect you against all."
