The Stone Raft by José Saramago

Man proposes, dog disposes, this very latest maxim is just as valid as the old one, we must give some name to whoever decides in the final analysis, for decisions don't always come from God, as is generally believed. There they took their leave of one another, the men heading for Figueira da Foz, which is nearest, the woman for the home of her hospitable relatives, but when Deux Chevaux, the brake already released, started moving, to everyone's astonishment the dog was seen to stand in front of Joana Carda, preventing her from passing. It didn't bark, it didn't bare its teeth, the gesture she made with the stick made no impression, after all, it was only a gesture. José Anaico, who was driving, thought his beloved might be in danger, and, once more the knight-errant, he brought the car to a sudden halt, jumped out, and ran to her assistance, a dramatic but somewhat ineffectual act, as he was soon to realize, for the dog simply lay down on the road.

Pedro Orce drew near, Joaquim Sassa too, the latter disguising his antipathy with an air of detachment. What does the beast want, he asked, but no one could give him an answer, not even the dog itself. Pedro Orce, as he had done before, went up to the animal and laid his hand on its huge head. The dog closed its eyes in a wistful manner at this caress, should such an adjective be appropriate here, we are talking about dogs, not about sensitive people who display their sensibility, and then it got up, stared at them one by one, gave them enough time to understand, and started walking. It walked about ten meters, stopped, waited.
