A Review From Library Journal:
If our pets could tell us what ails them, it would be easy to diagnose and treat their illnesses. Since this is not the case, we must be part sleuth and part psychic to interpret properly the clues they give us. These two titles by a veterinarian offer help in an easy-to-use format. The first chapter discusses emergency situations such as bite wounds and heat stroke, while the second chapter describes abnormal behaviors such as aggression and lethargy. The following eight chapters tour the animal's body from head to toe, offering thorough discussions of symptoms, diagnoses, possible causes, care, and prevention. Five appendixes include a checklist for good health, information on performing weekly home exams, breed disease predilections, a series of questions to answer before going to the veterinarian, and a list of recommended dosages of over-the-counter medications, herbs, and minerals. Highly recommended for pet care collections. Peggie Partello, Keene State Coll. Lib., Review Copyright 1998 Reed Business Information, Inc.

Anti-Aging for Dogs: A Longevity Program for Man's Best Friends (Hardcover)

A Review From Library Journal:
As more pets succumb early to cancer and other illnesses, their owners are searching for alternative forms of treatment. Simon has over 25 years of experience combining traditional and alternative forms of therapy. Together with canine behaviorist Duno, he has written a guide for the lay reader to use in concert with qualified veterinary consultation. The plan recommends dietary, environmental, and lifestyle changes along with regular veterinary check-ups, tests, and advanced medical and surgical techniques. The first section examines the aging process and how it affects each of the dog's organs and bodily functions. Part 2 covers preventive practices such as weekly home exams, exercise, grooming, diet, and obedience training. The final section discusses therapies for specific conditions. Readers will be interested in the authors' other books, including What Your Dog Is Trying To Tell You (LJ 3/1/98). Recommended for larger public libraries.
