Well, your dog may be just fine but realize that being at home all the time and THEN leaving a dog who has any tendency for separation anxiety and the results can be disasterous, because this type of dog has absolutely no tools for coping ("is she coming back, she doesn't usually leave me!!").
Here is an interesting website:

Now, I do not agree with using drug therapy, I just don't think it works nor is it the "answer" to the problem. BUT, I do have to say that what I do when I have a dog I think may be getting TOO DEPENDENT on me is just what they outline in this article: I send the dog off on a "vacation" with a friend. It might sound like the sink or swim method of helping a dog get over this problem, but in some cases it's the only way the dog learns that life goes on after Momma walks out the door!
The other thing I will say: after many years of recommending various books to puppy buyers and finding they rarely had/took the time to read them, I finally came across one that addresses the important "stuff" (separation anxiety included) in a very concise and easy to follow format. The book is "THE ONLY DOG TRAINING BOOK YOU'LL EVER NEED" by Gerilyn Bielakiewicz. It goes home with all my puppies and I have gotten nothing but good feedback on it.
At the same time, some people are just not capable of reading about how to train a dog and then going out and doing it with any success. Doesn't mean they are failures, they just need direction! In this case, when an owner's efforts don't seem to be getting anywhere, I highly recommend consulting an expert - and not ANY expert, one with Corgi experience. Most breeders are very happy to refer folks to such trainers.
