A puzzle

In my "Libraries" post the other day I mentioned a children's book that I loved when I was younger, but can remember neither the author nor the title. Maybe if I tell you what I do remember you might be able to help me... perhaps you've seen this book yourself?

I've tried googling what I do remember, but unfortunately have not come up with the answer. So here goes...

1. Children's book.

2. A lady has a pet dragon.

3. The lady wears colorful clothing (i.e. dresses)... or did she have colorful purses? No, I think it was dresses.

4. This book was published pre-1992, possibly in the '70s or '80s.

5. Had colorful pictures.

That's it... sad isn't it?
