The one absolutely unselfish friend than man can have in this selfish world is his dog
Dogs are not our whole life, but they make our lives whole
A dog is the only thing on earth that loves you more than you love yourself.
Perhaps one reason we are fascinated by cats is because such a small animal can contain so much independence, dignity, and freedom of spirit. Unlike the dog, the cat's personality is never bet on a human's. He demands acceptance on his own terms.
The dog is the perfect portrait subject. He doesn't pose. He isn't aware of the camera.
