A dog's life

A dog is a man's best friend, might be cliched, but yet i realized it all over again today. For those who have their doubts about it, see this movie, "Marley and me". It is about the life of a dog raised by a couple. The final scene of the movie sums it up quite well. The couple have just buried the dog and are walking back quietly when the narrator says this:

"A dog doesn't need a car, a house or other materialistic things,
He doesn't care if you are rich or poor,black or white, male or female.
All you have to do is give him your heart and he will give you his.
Now, about how many other people can you say the same thing?"
