Dogs

The more I see of men, the more I admire dogs.

Marquise de Sevigne

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.

Mark Twain

The average dog is a nicer person than the average person.

Andy Rooney 

Outside of a dog, a book is man's best friend. Inside of a dog it's too dark to read.

Groucho Marx
