Histories are more full of examples of the fidelity of dogs than of friends.

Animals have these advantages over man: they never hear the clock strike, they die without any idea of death, they have no theologians to instruct them, their last moments are not disturbed by unwelcome and unpleasant ceremonies, their funerals cost them nothing, and no one starts lawsuits over their wills.

Do you not see how God is praised by those in the heavens and those on earth? The very birds praised Him as they wing their way.

Be a good animal, true to your animal instincts.

Man, when perfected, is the best of animals, but when separated from law and justice, he is the worst of all. 

Every creature in the world is like a book and a picture, to us, and a mirror.

When the eagles are silent, the parrots begin to jabber.

Happiness is a warm puppy.

Man is the only animal for whom his own existence is a problem which he has to solve and from which he cannot escape.

One of the animals which a generous and sociable man would soonest become is a dog. A dog can have a friend; he has affections and character; he can enjoy equally the field and the fireside; he dreams, he caresses, he propitiates; he offends and is pardoned; he stands by you in adversity; he is a good fellow.

The righteous know the needs of their animals, but the mercy of the wicked is cruel.
