The book surveys the developmental stages of a dog's life, focusing on the training/parenting needs of each stage and paralleling these stages with those of our own children. The comparisons are interesting both for application to man's best friend and children. The key concept developed is what is leadership and what are the responsibilities of the pack leader (Alpha--male/female).
The text is very application-oriented and provides many examples, both positive and negative, of behaviors and responses.
Finally, the leadership skills discussed in the text may very well have applications beyond just dogs and children, perhaps business management as well.
Fun reading with many applications and yet doesn't fail to maintain the focus on developing a better relationship with your canine friend.
