Canine confidential : why dogs do what they do
(Book)

Includes bibliographical references and index.

For all the love and attention we give dogs, much of what they do remains mysterious. Just think about different behaviors you see at a dog park: We have a good understanding of what it means when dogs wag their tails-but what about when they sniff and roll on a stinky spot? Why do they play tug-of-war with one dog, while showing their bellies to another? Why are some dogs shy, while others are bold? What goes on in dogs' heads and hearts-and how much can we know and understand?
