We all certainly wish to live in as much harmony as possible with our dogs. Aggression issues not only pose a real challenge for dog owners but also shake the notion of blind trust and mutual friendship. Those seeking help from a professional may find that the training methods applied only make things worse. Most trainers still rely on punishment when a dog displays aggression. To change this, more knowledge about emotional and learning theoretical connections, needs, pain recognition, body language, and communication must be integrated into the dog world. Therefore, for the focal topic of this issue, we have gathered important input from experienced trainers and behavior consultants.
