The best friend a man has in this world may turn against him and become his enemy. His son or daughter whom he has reared with loving care may prove ungrateful. Those who are nearest and dearest to us, those whom we trust with our happiness and our good name, may become traitors to their faith. The money that a man has may be lost. It flies away from him, perhaps when he needs it most. A man’s reputation may be sacrificed in a moment of ill-considered action. The people who are prone to fall on their knees to do us honor when success is with us may be the first to throw the stone of malice when failure settles its clouds upon our heads. The one absolute, unselfish friend a man may have in this selfish world, the one that never deserts him, the one that never proves ungrateful or treacherous, is his dog. A man’s dog stands by him in prosperity and in poverty, in health and in sickness. He will sleep on the cold ground when the wintry winds blow and the snow drives fiercely, if only he can be near his master’s side. He will kiss the hand that has no food to offer. He will lick the sores and wounds that comes in the encounter with the roughness of the world. He guards the sleep of his pauper master as if he were a prince. When all other friends desert, he remains. When riches take wings and reputation falls to pieces, he is as constant in his love as the sun in its journey through the heavens. If fortune drives the master forth, an outcast in the world, friendless and homeless, the faithful dog asks no higher privilege than that of accompanying him to guard him against danger, to fight against his enemies. And when the last scene of all comes and death takes its master in its embrace and the body is laid away in the cold ground, no matter if all other friends pursue way, there, by his graveside will the noble dog be found, his head between his paws, his eyes sad but open in alert watchfulness faithful and true even to death. 28.
