No other animal yearns to please its master as does the dog.
Samuel Coleridge said: "The best friend a man has in the world may turn against him and become his enemy. His son or daughter may prove ungrateful. Those who are nearest and dearest to him may become traitors to their faith. The one absolutely unselfish friend that man can have in this selfish world, the one that never deserts him, the one that never proves ungrateful or treacherous, is his dog."
