“The non-scalpel addicts will be pleased to find detailed and argued non-surgical options. A useful tool for any practice.”  (Vet Nurses Today, 1 October 2015)“Overall, I believe this book will be a strong addition to any veterinarian’s library, especially those with a special interest in IVDD as well as general practitioners who manage patients with IVDD. It is fairly priced and is an important reference for any clinician seeking the most reliable, up-to-date information on this condition.”  (Journal of the American Veterinary Medical Association, 15 September 2015)
