I bought this book when my future son in law came home with an 8 week old Golden. Neither he or my daughter had any idea how to care for or train the puppy. I'm glad I chose this after reading many positive reviews, it's breed specific and behaviors really do vary depending on this. He's 8 months old now and they tell me often this book was invaluable, he's become an amazing addition to the family. I thought the book was a bit expensive but based on the results, worth every penny. Don't hesitate to buy it!
