I don't know if the author has implemented a dog training trick into the style of his book, but it is repetitive, especially the disciplining part (elaborates twice at length).
Useful with the information but not really anything about walking with your dog. Especially annoying as they mention a horror scenario which you can't help visualise happening to your own pooch. I think a topic on teaching your dog to 'heel' or 'stay' would of benefitted (and reassured) any reader of this book. Instead of sharing a condescending attitude, maybe could of shared some useful tips on how to teach your dog to avoid distractions while walking (what I was actually looking for when buying).
Most of the topics I kind of knew already, not to slate on the information, but basic training wise, this book is a neat intro on how to understand a little bit about your dog.
