Book excerpt: This book very succinctly lays out, in easy to read and understand terms, the sensitive periods of dog development. Better yet, the author explains why they are sensitive periods and exactly what the breeder should be doing during each one. The author also makes some painfully honest statements about what he feels the breeder's responsibility should be, and unfortunately, why people who breed dogs often do not take this responsib ility seriously. People who breed dogs and are not properly educating the puppies or who allow puppies to leave their mother at too young an age do everyone a disservice. The problem is people still get puppies from these sources because they do not know any better. This book is an excellent source for puppy buyers to educate themselves about what a good breeder should be providing. The author goes over the details of what breeders can do to make a lasting impact on the life of the puppy that they helped to bring into the world. The intimate understanding that this author has of the power of imprinting and other early puppy training is passed along to the rest of us in a way that everyone can easily utilize. No matter how you are involved "in dogs" this book will help to increase your understanding and enjoyment in the relationship that you create with your dog.
