�This third edition focuses on presenting evidence about breed predispositions to increased levels of disease in purebred dogs and cats; and it seems to succeed in including all the best and most recent findings in the existing body of scientific literature. The book is therefore a must for all small animal vets, leading breeders, breed organizations and others tasked with advising on how to improve the welfare of dogs and cats through better breeding.� - Peter Sandøe �The authors have relied on 'evidence-based veterinary medicine,' i.e. a solidly scientific basis for their claims. They have enumerated the problems that arise in hundreds of breeds of dog and cat, and any person contemplating the acquisition of a purebred animal is well- advised to study this book carefully. Doing so can help assure that the animals we profess to love do not live lives of pain, suffering, disease and misery.� - Bernard E. Rollin
