Anonymous More than 1 year ago
Dr. Merck’s book covered every aspect of animal cruelty from firearm injuries to neglect. It included not only domestic house animals but farm and livestock. She provided helpful forms for recording information, evidence, and tips for successful photo and video documentation at crime scenes. This book was specifically geared toward the forensics and crime scene aspect of animal cruelty. The book is written for an older audience, such as a college or graduate level student. The four column per two page set up did not work well for me. It was overwhelming at times, and I found myself having to go back and reread for complete comprehension. The book was not purely text; there were photos and charts scattered throughout. It gave tips, helpful information and how to protect animals as a veterinarian. It was a well written book and all the claims were backed up with evidence. I was amazed by the minuscule details that have to be discovered to ensure success in the courthouse. The writing style that Dr. Merck uses is a step by step process and gives the cold, hard facts. I would recommend this book as a credible and useful source to students pursuing veterinary forensics.
