Aggressive Behavior in Dogs is a comprehensive technical manual, written for animal behavior professionals. It outlines why dogs aggress, how technologists can manage aggressive behavior cases from initial contact through the functional behavioral assessment process, establishing behavior objectives, designing and implementing a systematic contingency management plan and working toward resolution from a behavioral orientation. Although the content relates to dogs, it could be applied to various species of companion animals. The third edition has been completely revamped and updated.
