“I recommend this book as a quick reference guide for enhancing technician training in a clinical setting. It is also an appropriate resource for an undergraduate course in small animal pathology for veterinary technicians.”  (Journal of the American Veterinary Medical Association, 15 March 2015)“This book's positive features include the concise reviews of various disease processes and the good quality images.”  (Doody’s, 29 August 2014)“Additional support is provided via a companion website that also offers review questions, case studies, and images from the book, making for a 'must have' reference for any veterinarian's library.”  (Midwest Book Review, 1 August 2014)
