Based on each chapter and the advice set forth in the book, the author seems to know what they are doing. They lay out clear advice on how to introduce your dogs to the idea of a baby, then ultimately how to introduce them when you bring the baby home.
The problem is that the case studies are written in a way that doesn't make the author sound very experienced as a trainer. The worst is a case study where the author details a situation where a dog is aggressive, he talks to the parents to learn about the dogs behavior, then recommends euthanizing the dog. I understand some situations are complicated, but no where in the case study does he mention trying to help train the dog. Wouldn't a dog trainer first try to help the dog change their behaviors before recommending death? I just lost all faith in the authors abilities as a trainer after reading that. If he said "we spent 2 weeks trying to teach the dog behaviors other than resource guarding, then we gave up.", I'd be a little more understanding.
Overall there are some good tips in the book and I feel like he could omit some of the case studies and convince us he's an expert, but currently the way it is written I am not convinced.
