The New Complete Pembroke Welsh Corgi (ISBN 0876052499)

a very informative text on the pembroke corgi:
The new complete pembroke welsh corgi offers quite a bit of information for fanciers of the breed. The history of the breed is well documented and includes rare photos of champion corgis. The text is written so as to interest both those who breed and show corgis, as well as those who are just interested in owning one as a pet. The health care information is informative and provides pet owners with important insight into corgi care. This is definitely one of the best references for the breed that I have seen.

Definitive Corgi Book:
There are a number of "breed" books out there on the Pembroke, but this is the official one. Mostly geared toward people who are interested in conformation showing and breeding, it is the only book with extensive photographs and discussions of bloodlines which have influenced the breed. Like all books by breed fanciers, it does not say anything critical about anything. If you want to find out about problems in the breed or in certain lines, you won't find it here (for example, temperament, genetic health, over-popularity). It does have short but informative sections on other topics besides showing and breeding. It is an excellent example of its kind. Certainly all Pembroke breeders should have a copy (but they probably do).

The best corgi book out there:
This is the most complete corgi book I've found. There's so much information I can't begin to do it justice - from history of the breed to prime examples of corgis, this book blows away every other dog book I've ever had my hands on (for any breed). Though this book might cost more, it is well worth it - I bought 5 or 6 Corgi books and this one makes the rest look like cheap info pamphlets.
