Query: Best Cavalier Book!

This is an excellent book for anyone interested in Cavaliers, from the pet owner to the breeder and show exhibitor. Full of specific information related to Cavaliers and personal anecdotes, all aspects of the breed are covered, including history, health, grooming, breed standard, breeding, and Cavaliers in art. Photos and/or drawings illustrate every page - show champions as well as informal photos show the charm of the breed. I have several books on Cavaliers, but this is the best, and the one that I always recommend to others.
