I just went through reading a bunch of reviews with half of the people saying this training method is abusive. And then the other half said it was the best they have ever seen. I would be willing to bet anything that those who praise the book are the ones you see in the park with the dogs who are well behaved and not bothering anyone. And I would bet that those who trash the book are the ones whose dogs are running out of control, chasing people, and ruining picnics (they're probably also the ones with dog hair all over the sofa and bed because they believe their dog should have the choice to sleep on the bed, sofa, or wherever the dog pleases). My best advice is to not read the reviews. Instead, read the book (which many of the trashers have made comments that suggest that they didn't even read the book). And make your own decision. You will likely decide to use the parts of the book that fit within your comfort zone. I highly suggest using at least the basic training.
