Answer
Hi Nancy,
    Each time your dogs do something you don't approve of, do the following:

1. Make your hand flat, palm facing the floor

2. Curve your fingers inward, but not to the point of making a fist

3. Take your hand in this position and firmly nudge your dog with the ends of your fingers. Now say "Chtt!". Be sure to say it in a deep, powerful voice, as if you are the king of the world! :P LOL
The reason I say that is because if the dogs sense any fear whatsoever, they will completely ignore you and treat you like another dog (not the pack leader).
    I highly recommend purchasing one of these books: http://cesarmillaninc.com/products/books.php
They are must-haves for all dog owners!
