If you pick up a starving dog and make him prosperous he will not bite you. This is the principal difference between a dog and man.

You've been acting like Jesus owes you a favor, but he's a little smart for you to fool.

Heaven is by favor; if it were by merit your dog would go in and you would stay out. Of all the creatures ever made (man) is the most detestable. Of the entire brood, he is the only one... that possesses malice. He is the only creature that inflicts pain for sport, knowing it to be pain.

The dog is a gentleman; I hope to go to his heaven not man's.

A man's character may be learned from the adjectives which he habitually uses in conversation.

Man is the only animal that blushes, or needs to.
