Foreward: 

It is first about Understanding and Helping Your Reactive Dog

Many dog owners see reactive behaviours like lunging, barking, stiffening, growling and assume it’s aggression. But often, reactivity comes from a place of feeling trapped, overwhelmed, anxious, or misunderstood. The dog isn’t choosing to “be bad”; they’re trying to make sense of what they feel, especially when they don’t yet have the tools to cope.

At Good Dog Training and through our Dog Club programme, we help you and your dog uncover what’s really going on, build trust and communication, and work step by step out of those reactive habits.

6 Common Causes of Dog Reactivity Discussed in Detail Below: 

Reactivity isn’t about being stubborn or “naughty.” It’s rooted in how safe, confident, and supported a dog feels in different environments. Here are the most common causes which we will address in more detail below:

Reactivity Reason #1: Feeling Unsafe or Trapped

When on lead, a dog has no option to move away. Their natural choice to increase distance from what worries them is removed. Barking, lunging, or growling is often their way of saying, “I need space,” not “I want to fight.”

Reactivity Reason #2: Lack of Confidence

Just like people, dogs vary in confidence. A dog who hasn’t built up trust in themselves or their handler may feel overwhelmed in busy places, around new dogs, or when facing novel experiences.

Reactivity Reason #3: Lack of Social Exposure

Dogs who miss out on varied, positive experiences during puppyhood (roughly 3–14 weeks of age) may find the unfamiliar scary. Without practice, they struggle to process new situations calmly.

Reactivity Reason #4: Negative Experiences

Dogs learn strongly from “one bad moment.” Being rushed by an off-lead dog, startled by loud noises, or handled roughly can leave a lasting imprint. The dog then anticipates danger and reacts pre-emptively to protect themselves.

Reactivity Reason #5: Miscommunication

Dogs communicate first with subtle body language; Ears pinned back, yawning, sniffing, or turning away. When these signals are ignored or misunderstood, they may escalate to louder behaviours (barking, lunging) to be “heard.”

Reactivity Reason #6: Stress Thresholds & Triggers

Stress builds like water in a bucket. A dog may appear fine until that “last drop” tips them over the edge. Owners often miss the smaller stress signals that build up before the explosion.

What can you do with a Reactive Dog right now?

Even before joining Dog Club, you can help your dog with these simple steps:

Observe Body Language:

Watch for early stress signals like, licking lips, yawning, stiff posture, or turning away. Intervene early to prevent escalation.

Offer Low Stress Walks:

Choose quiet routes. Reward calm behaviour frequently. Don’t measure success by distance, but by relaxation.

Establish Foundations At Home:

Practise focus, recall, sit, and stay in distraction-free environments. This builds communication without pressure.

Play Engagement Games:

“Look at me,” hand touches, or treat-chasing games create strong, positive associations with you.

Avoid Punishment:

Don’t scold growling or barking, it’s communication. Instead, calmly create distance and reset.

Celebrate Small Wins:

Progress comes in steps. Each calm moment is a success worth rewarding.
