Men, my dear, are very queer animals—a mixture of horse nervousness, ass stubbornness, and camel malice.

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

I do not mean to call an elephant a vulgar animal, but if you think about him carefully, you will find that his nonvulgarity consists in such gentleness as is possible to elephantine nature—not in his insensitive hide, nor in his clumsy foot, but in the way he will lift his foot if a child lies in his way; and in his sensitive trunk, and still more sensitive mind, and capability of pique on points of honor.

Happiness is a warm puppy.

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

There be beasts that, at a year old, observe more, and pursue that which is for their good more prudently, than a child can do at ten.

If you are a dog and your owner suggests that you wear a sweater, suggest that he wear a tail.

Be a good animal, true to your animal instincts.

Life is no way to treat an animal.

Man is merely a more perfect animal than the rest. He reasons better.

Of all the creatures that breathe and creep on the surface of the earth, none is more to be pitied than man.

Animals are such agreeable friends—they ask no questions, they pass no criticisms.

In every man is a wild beast; most of them don’t know how to hold it back, and the majority give it full rein when they are not restrained by terror of law.
