Not only Scared Dogs. My opinion is that nearly all dog owners can benefit from reading this book. What is normal human behavior can be stressful for a dog in a household. This was certainly helpful for all looking at each of my dogs and identifying areas where I may need to tweak things for them. So even though there were many things I did already know there was a lot of information that I did not know or that I had not thought of in this particular context. Very helpful.
