Aggressive and Fearful Behavior in Dogs: Understanding the Misunderstandings

I believe there is a significant lack of knowledge about animal social behavior, especially in the dog training world. Aggressive and fearful behavior are probably the most misunderstood, seconded by dominant and submissive behavior. These misunderstandings are at the origins of stereotypes, labels, and popular trends, creating much confusion among professionals, dog owners, and the new generation of trainers.

The term “reactivity” is trendy and an easy label to explain all dog behaviors. There are several explanations and definitions of “reactive behavior,” the most popular being “Reactivity: fear, aggression, or frustration responses that are over the level that dog-savvy humans consider ‘normal.’” (Stewart, G. 2016. BAT 2.0). According to that definition, aggressive, fearful, dominant, and submissive behaviors become reactive just because of their high intensity. How do we, then, label any low-intensity versions of the same behaviors? Does that mean a dog can show a little aggressive behavior but as soon as it offers more of the same, the behavior changes and becomes reactive? Or is it only the name that changes? How does that work? Are these low-intensity behaviors normal even when displayed in the wrong context, e.g., showing aggressive behavior when submissive behavior would be the most obvious beneficial strategy?

The term “fear-aggression” doesn’t make sense at all from an ethological point of view. How can two different behaviors (evolutionary strategies) with quite distinct functions be present simultaneously?

I have compiled a comprehensive set of papers about this subject from authorities in animal behavior. I will update it regularly.

I expect these articles will help you to formulate an educated opinion about this topic.
