Often, when a dog owner finds that his pet has become excited, he can't tell if the excitement indicates joy or anxiety. This book shows how to pick up on all the signals that dogs send out through their voices, body language, postures, tail-wagging, and more. The Dog Decoder helps readers understand what dogs are trying to say to their human masters. Aided by vivid color photos, author David Alderton describes how dogs communicate inside the home, out on the street, encountering visitors and other animals, walking off their lead, and at play in the park. Alderton has carefully selected, captioned, and annotated photos to help fellow dog owners gain a clear understanding of their pet's behavior. He advises on how to predict a dog's reaction to a particular situation, enabling owners to use that knowledge for a more enriching and less stressful relationship with their dog. More than 100 color photos.
