Because they can tell you they love you, even though they don't say the words, and they mean it more than most people who say "I love you" mean it. Because they are more loyal than any person I can ever imagine. Because they always smile and wag their tail when you get back home, even if you have only been away for 10 minutes. Because dogs can make a simple walk in nature one of the mst magical experiences. Because they haven't lost the meaning of life. HUmans always want more, more, more and we are never happy. Give a dog love, a warm place to sleep, water, food, toys and a few walks and I guarantee you they are happy.
