Scott Sheaffer, CBCC-KA, CDBC, CPDT-KA

In this insightful episode of the USA Dog Behavior Podcast, certified dog behavior consultant and behaviorist Scott Sheaffer delves into the complex topic of canine aggression. He explains that aggression in dogs often stems from fear rather than inherent hostility, serving as a defensive mechanism to create distance from perceived threats. 

Sheaffer distinguishes between reactivity and aggression, highlighting how reactive behaviors like barking or lunging can escalate into aggression, especially when dogs feel cornered or threatened. Key factors contributing to fear-based aggression—such as lack of socialization, past trauma, genetics, and medical issues—are explored, offering listeners a deeper understanding of their dog's behavior.

Sheaffer also shares practical strategies for addressing aggression, including desensitization, counter-conditioning, and professional training. Emphasizing the importance of patience and proper intervention, he reassures owners that many dogs can overcome these challenges with the right approach.

Welcome to the USA Dog Behavior podcast! I'm Scott Sheaffer, a certified dog behavior consultant and behaviorist specializing in all types of canine behavior issues. Today’s episode: Why Are Some Dogs Aggressive?

Aggression in dogs is a complex behavior that normally stems from fear rather than inherent hostility. Understanding the root cause of aggression is crucial for effective management and rehabilitation.

Fear is the primary driver of aggressive behavior in dogs. When a dog perceives a threat—be it a person, another dog, or an unfamiliar object—it may react aggressively to protect itself. This type of aggression is a defensive mechanism aimed at increasing distance from the perceived threat. In the dog behavioral world, we call this defensive aggression, even though it appears as if it is purely offensive in nature.

It’s important to distinguish between reactivity and aggression. Reactivity is the umbrella term we use when a dog overreacts to stimuli. This overreaction can manifest as aggressive and/or avoidant behaviors. Examples of reactive behaviors include barking, lunging, trying to get away, hiding, and a host of other behaviors. 

In my experience I’ve found approximately 90% of dogs choose aggression when they are reactive to humans or other dogs. In short, most dogs who are fearful of other dogs or humans react with aggression toward them instead of just trying to get away.

There are a number of reasons for this, one of which is leash-frustration which I cover in other podcasts and blog posts.

Several factors can contribute to fear-based aggression:

  • Lack of Socialization: Dogs who haven’t been exposed to various people, animals, and environments during their critical socialization period (i.e., the first 16 weeks of life) may develop fear responses to unfamiliar stimuli.
  • Past Trauma: Negative experiences, such as abuse or neglect, can lead to heightened fear and defensive aggression.
  • Genetics: Some breeds may have a predisposition to reactive behaviors, especially if bred for guarding or herding.
  • Medical Issues: Pain or neurological problems can cause changes in behavior, including aggression.

Addressing fear-based aggression involves a combination of strategies:

  • Desensitization and Counter-Conditioning: Gradually exposing the dog to the fear-inducing stimulus in a controlled manner while associating it with positive experiences can reduce fear responses.
  • Professional Training: Working with a qualified dog behaviorist can provide tailored strategies to manage and modify aggressive behaviors.
  • Medical Evaluation: Consulting a veterinarian to rule out or treat underlying medical conditions if indicated.

Understanding that aggression in dogs normally stems from fear rather than malice on the part of the dog is key to addressing the behavior effectively. With proper intervention, many dogs can greatly improve and lead much happier lives.
