Our pets are living longer than ever before-and we want nothing more than to have them by our side in good health for as long as possible. But what does longevity mean for dogs, cats, and other pets? Is it just about more years-or about better years? This book offers the first comprehensive overview of the topic of longevity in pets. It explains the biological basis of aging, shows the influence of nutrition, exercise, environment, and mental health, and introduces modern options for prevention and therapy-from vaccination programs and microbiome research to innovative approaches such as stem cell therapy and geroprotectors. Economic, social, and ethical dimensions are also examined: What responsibility do we have as owners? Where are the limits of life extension? And how can lifespan and quality of life be reconciled? A book for anyone who wants to better understand the lives of their animal companions, shape them more consciously, and extend them.
