Query: Not worth the read

I've read several dog behavior books and worked with dogs for years. This book, however, was disappointing. He begins with the assumption that most dogs owners not only don't know how to train a dog, but actually seriously mistreat their dogs. He presents techniques in two veins. Some involve scaring the dog into doing the right thing by throwing things at him/her or by making a loud noise. Others are reasonable, positive, reward-based strategies, but he presents them as if it were some great, original idea that no one had ever thought of before. There are plenty of much better dog behavior/training books out there that are much better reads.
