Animal testing is a controversy that has raged for hundreds of years. Some people view experiments on dogs as necessary for human medical progress, while others argue that the practice is barbaric. When the author adopted Marty-a beagle rescued from a research laboratory-she found herself rehabilitating a terrified dog with a traumatic past. She soon discovered the well-kept secret of painful and often fatal testing on dogs. This book details what the author has learned about the past and present of laboratory testing on dogs, life after laboratories and the hope for a future without animal testing. Interviews with rescue organizers and adoptive families reveal the struggles of removing dogs from laboratories and acclimating them to daily life. Scientists discuss the ethics of dog research and advocate for new biomedical technologies. Fundamental change is brewing, with the public, scientists and governments urging the use of new technologies that can replace testing on animals and yield better results.
