Book excerpt: Veterinarians are seeing an explosion of health problems in cats, dogs, and horses -- chronic diseases, immunological illnesses, cancer, and more. Conditions thought to affect only one breed are showing up in others. This illustrated book explores the causes and treatments. During the past 30 years of clinical work, renowned veterinarian Dr. Alfred Plechner has identified a widespread but unrecognized deficiency in the endocrine-immune system of these animals that is wreaking havoc on the pet population. Pets at Risk is his proven program of intervention and care. The book is designed to be used jointly by pet owners and vets, since part of the treatment involves pharmaceuticals along with a healthy diet and careful attention to food allergies. Positive results from Dr. Plechner's practice and that of other vets show how these illnesses can be minimized or even eradicated. This guide truly offers a breakthrough method for keeping your pets healthy and safe from risk.
