To add to Summerrain's excellent post, here is a very helpful article by Dr. Sophia Yin (a vet and behaviorist whose work with counter conditioning is amazing) on crate training and other basic puppy training. She gives step by step instructions, lots of illustrations.

(I'm a big fan of her book, "How To Behave So That Your Dog Behaves" )
Hope you and Whiskey are enjoying learning from each other.
