On first publication, Clinical Medicine of the Dog and Cat was hailed by the market and reviewers as a ground breaking work being the first fully illustrated textbook of small animal clinical medicine. The first edition was extremely successful. In this major revision, the coverage and author team have been further enriched by the addition of new chapters on Immunology, Nutrition, Fluid Therapy, Pain Management and Clinical Toxicology. While covering all the major areas of internal medicine of the dog and cat, the emphasis is on brevity and the more common disorders. The book is organized by body system, and each chapter is structured in a consistent way, providing the definition of each disorder, its causes, clinical features, differential diagnoses, diagnosis and management options. This practical, focused text is richly illustrated throughout by 1,505 clinical color photographs, imaging, diagrams and tables (450 additional pictures to the first edition). It will be of lasting value to practitioners and students as a learning resource and permanent reference.
