Communication is the mirror of the relationship. Only those who understand the other can make themselves understood. This is the prerequisite for a harmonious relationship between dog and man and any successful education. Jan Nijboer deciphers the secrets of canine communication and describes in many case studies how dogs talk to their conspecifics, how they communicate with humans and to which misunderstandings the wrong interpretation can lead. He explains how we can make dogs understand us correctly and how we can become a true social partner for our dog, whom he can follow with confidence.
