This book has a lot of helpful training tips and techniques. I decided to read it after our rescue dog completed Fundamentals and Advanced training at Petco, but we were needing more. It was the winter and not great timing to try an in-home trainer. We went slowly working through this book, and I only wish I picked it up sooner!
I love the idea of treating walks and training as a game that your dog thinks is fun. This really worked for us, and you can keep practicing/reinforcing the exercises well beyond 6 weeks.
I also appreciated the writing feeling conversational, understanding, and not overly serious. There is humor mixed in and the chapters are fairly concise. I think I would naturally gravitate to in-person training or a video, but reading this book and applying what I read was more helpful than I could have imagined!
