"The one absolutely unselfish friend that humans can have in this selfish world,

the one that never deserts them,

the one that never proves ungrateful or treacherous is their dog."

~George Graham Vest, Senator of Missouri, 1855

It is commonly said and believed that a dog is "a man's best friend."

"Is a dog really a man's best friend?"

Holy Bible says,

There is a friend (Jesus) who sticks closer than a brother. (Proverbs 18:24).
