The Horseowner's Guide to Lameness could easily be the one and only book every horseperson will ever need on the subject.From this book, readers can learn the details of skeletal and muscular equine anatomy through written description and excellent illustrations. Any imaginable lameness or unsoundness is covered here, with details of causes, symptoms, treatments and prognosis. The book also includes photos and x-rays to complete the picture.The one downfall of this book is that it is rather technical. It is not written in layman's terms nor does it waste page space with extraneous words. As a reference to horse owners and riders this book is invaluable, but it does require a certain amount of familiarity with anatomy terminology in order for the user to reap the full benefits. However, for anyone who owns or cares for horses, The Horseowner's Guide to Lameness is a necessity.
