Do dogs have a paper deficiency?

We have been so proud of our high-energy puppy because it seems that she is beginning to calm down a bit...or so we thought. When we first got her we crate-trained her and it has worked beautifully. Here we are a year later and she's doing so well, so of course it is time to allow her some freedom when we leave. We started allowing her to stay out when we left for short periods of time to run to the store and she has worked all the way up to 4 and 5 hours at a time! We are so proud of her...she's such a good girl! She doesn't get on the furniture, she loves laying on her bed, she plays with her toys and doesn't chew things that don't belong to her! She's such a good girl!

Having said all of that, I've been working on Thank You notes and I am so excited because they are almost finished. They stay on "my" chair and every day I sit and write a few. The other day we left for an hour and a half and when we returned, Lucy had EATEN the gift log that I had recorded everything in, several of the Thank You notes, and way too many envelopes to count. I mean shredded, ripped to pieces, digested, strewn all over the floor, and tore pages clean out of the book. You don't want to know how the hormonal pregnant lady who can't remember anything and had almost gotten all of them written reacted.
