Editorial Reviews

From the Publisher
Differential Diagnosis in Small Animal Medicine provides an excellent reference tool for formulating differential diagnostic problem lists for small animal patients.... The author has succeeded in providing a textbook that allows veterinary students and clinicians with all levels of experience to promptly formulate a complete differential diagnosis list for problems in small animal medicine. The text provides an inclusive and concise reference in an easy-to-navigate format and is recommended for use in private clinical or academic settings." Journal of the American Veterinary Medical Association

“Veterinary students [and] general practitioners should all find this book helpful…saves valuable time…useful source of information for anyone who needs a differential diagnosis list quickly…”
Doody’s Review Service

“It is a very user-friendly text that takes a very systematic approach to medicine..... compact and could easily slip into a drawer and be accessed easily and quickly. I will definitely keep it in my drawer as a quick reference.”  Tech News

Doody's Review Service
Reviewer: Chantal A Imbs, DVM (University of Illinois College of Veterinary Medicine)
Description: This book of differential diagnosis in small animal medicine is organized in seven parts, containing lists of differentials, some diagnostic algorithms, and checklists for diagnostic investigations.
Purpose: This a very useful book to formulate a differential list from the clinical, laboratory, radiographic, ultrasonographic and electrodiagnostic findings. The sixth section describes the most common diagnostic procedures.
Audience: Veterinary students, general practitioners, interns, and residents should all find this book helpful. It saves valuable time by bringing information from various sources together.
Features: This concise, thorough reference covers numerous differential diagnoses. The diagnostic procedures section details comprehensively the indications, technique, and interpretation of common tests. The diagnostic algorithms are also helpful.
Assessment: This high quality, rapid reference book concentrates information from multiple sources about major problems in small animal medicine. It is a useful and appropriate source of information for anyone who needs a differential diagnosis list quickly, or information about diagnostic procedures.
