America's leading undercover animal investigator, Pete Paxton, has, among other exploits, infiltrated more than seven hundred puppy mills, worked undercover to close one of the largest and most infamous puppy mills in the United States, and shuttered the most notorious trafficker of dogs for experimentation in history. In this book, he shares stories of the amazing dogs he has rescued and brought to loving families, and also offers invaluable guidance and wisdom for anyone living with rescue dogs. Far too many people think rescue dogs have irredeemable anxieties, behavior issues, or other problems. In truth, rescue dogs can—and do—become wonderful companions. This groundbreaking book will help readers understand these dogs' unique ways of thinking, learning, and loving, and leaves no questions unanswered about the plight of dogs commercially bred in the United States—and what every dog lover can do about it.
