The Radetzky March by Joseph Roth:
They sat, a bit crowded, in small sleighs; the bells jingled bravely, the brown horses raised their cropped tails and dropped big, round, yellow steaming turds on the snow. The regimental surgeon, who had been indifferent to all animals throughout his life, suddenly felt homesick for his horse. He will survive me! he thought. His face betrayed nothing. His companions were silent.
