The information is presented in a question and answer format. The answers are of sufficient length to provide detail on the topic at hand. The questions presented in this book should appeal to veterinary students, general practitioners, surgical residents and specialists with an interest in soft tissue surgery. The topics are presented as clinical cases in order for readers to consider the topic and test their knowledge. The questions in this book were provided by an international group of veterinarians, dedicated to advancing our profession and teaching the art and science of surgery. The contributors have made an effort to make this book thorough and up to date, but the reader should be aware that soft tissue surgery has some controversial topics and alternative answers to some questions do exist. I enjoyed the writing of this book; my hope is that you enjoy the book and learn from it. This book was written to encourage knowledge. It was written with the hope that readers will strive to understand the act of surgery, but also strive to understand medical and surgical decisions regarding diagnostics and perioperative care of small animals.
