The world would be a nicer place if everyone had the ability to love as unconditionally as a dog.
If you pick up a starving dog and make him prosperous, he will not bite you; that is the principal difference between a dog and a man.
A dog will teach you unconditional love. If you can have that in your life, things won't be too bad.
There's a saying. If you want someone to love you forever, buy a dog, feed it, and keep it around.
