If you pick up a starving dog and make him prosperous, he will not bite you; that is the principal difference between a dog and a man.
-Mark Twain

You can say any foolish thing to a dog, and the dog will give you a look that says, 'Wow, you're right! I never would've thought of that!'
- Dave Barry

If you think dogs can't count, try putting three dog biscuits in your pocket and then give him only two of them.
-Phil Pastoret
