Why Dogs Are Reactive: Understanding Canine Behaviour

Dogs are known for their loyalty, playfulness, and the bond they share with their human companions. However, anyone who has spent time with dogs has likely encountered moments when their furry friend exhibits reactive behaviours. Whether it’s barking aggressively at another dog, lunging at a passing cyclist, or becoming anxious around strangers, reactivity in dogs is not uncommon. But what exactly causes these behaviours? In this blog post, we’ll dive into why dogs are reactive and how to address this issue in a compassionate and effective manner.

What is Reactivity in Dogs?

Reactivity in dogs refers to an exaggerated response to stimuli, whether that’s other animals, people, or environmental factors. Reactive behaviour can manifest as barking, growling, lunging, or even snapping, often in situations where a more calm or neutral response would be expected. It’s important to note that reactivity isn’t always the same as aggression, though it can sometimes lead to aggressive behaviour if not addressed.

Reactivity can stem from several underlying factors, including fear, frustration, anxiety, or a lack of proper socialisation. Understanding why dogs behave in this way can help pet owners better manage their dogs’ reactivity and improve their overall behaviour.

1. Fear and Anxiety: The Root Cause

Fear is one of the most common reasons for reactive behaviour in dogs. When a dog feels threatened or scared, its natural response is to protect itself. This can lead to reactive behaviours, like barking or lunging at a perceived threat, such as another dog, a loud noise, or a stranger.

For example, a dog that has not been properly socialised with other dogs may react aggressively when it encounters a new dog. Similarly, a dog that has had a negative experience with strangers may become fearful and reactive around new people. Fearful reactions are often triggered by a lack of confidence or a traumatic experience, which can lead to increased anxiety.

2. Frustration: Not Getting What They Want

Another common cause of reactivity is frustration. Dogs can become reactive when they are unable to get what they want, such as when they’re on a lead and unable to approach another dog or person they are interested in. This is often referred to as "lead reactivity."

Lead reactivity occurs when a dog is prevented from fulfilling a natural instinct, such as socializing or exploring. The dog may react by pulling, barking, or lunging at the lead, which can be a direct result of frustration. The more a dog is restrained from interacting with its environment, the more likely they are to react in a heightened manner.

3. Lack of Socialisation: Learning from a Young Age

Socialisation is an essential part of a dog’s development. Puppies who aren’t properly exposed to a variety of people, animals, and environments can grow up fearful or unsure of new experiences, which can lead to reactivity. A lack of early socialisation can make dogs more sensitive to unfamiliar situations and less adaptable when faced with change.

A dog that hasn’t learned how to appropriately interact with other dogs or people may become reactive when encountering new stimuli. This behaviour is often seen in dogs that have not been socialized to other dogs during their critical developmental period (around 8-12 weeks of age).

Please note that inappropriate socialisation can be more damaging than a lack of socialisation.

4. Genetics and Breeds: Some Dogs Are More Prone to Reactivity

Certain dog breeds are naturally more predisposed to reactivity, especially those that were originally bred for guarding or herding. Breeds like Border Collies, German Shepherds, and Rottweilers, for instance, are known to be more alert and protective, and may react strongly to unfamiliar situations or perceived threats.

While genetics play a role in a dog’s temperament, it's essential to remember that reactivity can still be managed and reduced through training, socialisation, and behaviour modification techniques. A dog’s breed or genetic makeup may influence their initial reactions, but it does not mean they are doomed to be reactive forever.

5. Previous Traumatic Experiences: Emotional Scars

Dogs, like humans, can carry emotional scars from traumatic experiences. If a dog has been abused, neglected, or has experienced a negative encounter, it may develop reactive behaviours as a way to protect itself from future harm. Traumatic experiences can cause a dog to become fearful or overly defensive in similar situations, leading to reactivity.

For example, a dog that was attacked by another dog might become reactive when encountering other dogs in the future, even if the new dog poses no threat. The fear of being hurt again can trigger a heightened, reactive response, even if the situation doesn't warrant it.

How to Manage and Reduce Reactivity in Dogs

Understanding why dogs are reactive is the first step in addressing the issue. Here are some strategies that can help manage and reduce reactivity in dogs:

1. Positive Reinforcement Training: Rewarding calm behaviour and redirecting a dog’s attention away from triggers can help reinforce desirable responses. Rewarding your dog for remaining calm in the presence of a trigger is key to modifying their behaviour.

2. Desensitisation: Gradually exposing your dog to the stimuli that trigger their reactivity in a controlled manner can help reduce their sensitivity to these triggers over time. This must be done slowly and with plenty of positive reinforcement to prevent overwhelming the dog.

3. Counter-Conditioning: This technique involves changing a dog’s emotional response to a trigger. For example, if a dog reacts negatively to the sight of other dogs, you can pair the sight of another dog with a positive experience, like receiving treats. Over time, the dog learns to associate the trigger with something positive.

4. Consult a Professional: If your dog’s reactivity is severe or difficult to manage on your own, seeking the help of a professional dog trainer or behaviourist is highly recommended. They can provide tailored strategies and guidance to address the underlying causes of your dog’s reactivity.

Conclusion

Reactivity in dogs is a common behaviour that can stem from a variety of factors, including fear, frustration, lack of socialisation, genetics, and past trauma. Understanding the root cause of your dog’s reactive behaviour is essential in helping them lead a calm and confident life. With patience, training, and positive reinforcement, most dogs can learn to manage their reactivity and respond more appropriately to their surroundings.

If your dog struggles with reactivity, remember: it’s not a hopeless situation. With time and effort, your dog can learn to feel more comfortable and secure in their environment.
