Like their human parents, dogs have been getting sicker over the past few decades. Why? Scientists are beginning to understand that the diseases affecting humans—cancer, obesity, diabetes, organ degeneration, and autoimmune disorders—also afflict canines. As a result, our canine companions are vexed with health problems throughout much of their lives and have shorter life spans. The Forever Dog gives us the tools to protect our four-legged friends. Rodney Habib and Dr. Karen Becker talked to top geneticists, microbiologists, and researchers, and interviewed people around the world whose dogs have lived into their 20s and even 30s. The result is this unprecedented and comprehensive guide, filled with practical information, invaluable advice, and inspiring stories about dogs and the people who love them.
