Hello, I have a book called "The new encyclopedia of the dog" by Dr. Bruce Fogle and it has the CWD in it. Its only gives you a small amount of information about two pages but it was the only book I could find in English myself. It helps as a start, covering history and other tid bits but you will get a better idea about the breed and weither you want to pursue more information. I agree everyone should try learn another language, Im trying to learn French.
