The dog's conformation is gone over from the tip of their nose to the tip of their tail. Ever wondered why your breed standard called for cat feet versus a hare foot? Ever wonder what the ideal should angulation was and why (though admittedly I have read other works that argue this author's view)? Wonder why a slightly sloping pastern is generally preferred over a straight one? All these questions and then some are covered in this book. I found it really interesting to read and I feel that it gave me a better understanding of some of my dogs flaws and where I need to be watching out.
The only draw back that I saw in this book were the illustrations. On the whole they were pretty helpful. However, there were a few where I felt the illustrations didn't adequately describe what they were supposed to be describing. There were a few where comparisons were being drawn between a correct form of something and an incorrect form of something and I felt that the drawings were so similar that there wasn't a very obvious contrast between the two. The descriptions are pretty good, but there were a few instances where a really obvious illustration that showed the differences would have helped a whole lot more.
Overall, I definitely recommend this book to anyone interested in why a dog is built the way they are. It's a good read and not too dry considering the subject.
As a Heffner update, he's not a whole lot better. There are moments where he seems fine, but generally he's still pretty uncomfortable and I'll be calling my vet tomorrow to make an appointment for him.
