Book excerpt: The world of veterinary medicine is changing. People are realizing that if alternative medicine is better for them, it's better for their pets, too. Dogs are visiting acupuncturists, chiropractic doctors, and homeopaths. Still, many dog owners are unaware that such simple measures as changing their pet's diet and using vitamins, herbs, and other natural cures can help prevent or heal ailments ranging from excessive scratching to depression to a host of serious diseases. The Veterinarians' Guide to Natural Remedies for Dogs is both an introduction and a guide to the vast world of natural healing methods, treatments, and foods now available for dogs. Author Martin Zucker offers advice from dozens of holistic practitioners and licensed veterinarians, who share their recipes, insights, and "prescriptions." Here dog owners will find information on everything from nutritional supplements to massage therapy, as well as how these treatments can be used alone or in conjunction with traditional medications and surgical techniques.
