Dogs are a part of nearly 40 percent of United States households.  With this in mind, author Linda P. Case has written the definitive textbook on dogs and their care.  Completely updated and revised, the second edition of The Dog covers four areas of compelling interest: the bond between dogs and humans, canine behavior, canine health and disease, and canine nutrition.  Aiming to enhance the human-dog bond, author Case uses clear, understandable writing to explain selective breeding, training principles, solution to common behavior problems, diet and nutrition, and preventative health care.  Case liberally uses distinctive figures and tables, current references plus suggested readings, and a thorough glossary to aid in comprehension.  More in-depth that most dog books, The Dog will prove to be an indispensable tool for undergraduate companion animal courses, veterinary technician courses, and dog care/training courses.  In addition, it will serve as a valuable resource for professional breeders, trainers, exhibitors, and veterinary clinicians.
