If you’ve ever seen your dog suddenly lunge, bolt, or freeze in place, you’ve witnessed what’s known as the “fight, flight, or freeze” response. As a dog trainer and behaviourist, I see these behaviours every day—especially in dogs who are anxious, reactive, or have a history of trauma. Understanding these responses is the first step to helping your dog feel safe and supported.
What Are Fight, Flight, and Freeze Responses?
These are natural, instinctive reactions to perceived threats. When a dog feels scared or overwhelmed, their nervous system responds in one of three main ways:
– Fight: The dog tries to make the scary thing go away—by barking, growling, lunging, snapping, or even biting.
– Flight: The dog tries to escape the situation—by running away, pulling on the lead, hiding, or avoiding eye contact.
– Freeze: The dog “shuts down”—becoming very still, refusing to move, or even collapsing to the ground. This is often mistaken for stubbornness, but it’s actually a sign of overwhelm.
Why Do Dogs React This Way?
Fight, flight, and freeze are survival mechanisms. In the wild, these responses help animals stay safe when faced with danger. For our pet dogs, these same instincts kick in during stressful or confusing situations—like meeting new people, encountering other dogs, hearing loud noises, or being handled in ways they’re not comfortable with.
What Do These Behaviours Look Like?
– Fight: Raised hackles, stiff posture, direct staring, barking, growling, snapping, or biting.
– Flight: Cowering, backing away, trying to escape the lead, running to another room, hiding under furniture.
– Freeze: Suddenly stopping, refusing to walk, lying down and not moving, glazed eyes, or holding their breath.
How Should Owners Respond?
– Don’t punish: These behaviours are not “bad” or “disobedient”—they’re signs your dog is overwhelmed. Punishment can make things worse by increasing fear.
– Create distance: If possible, calmly move your dog away from the trigger to help them feel safer.
– Offer support: Use a calm voice, avoid sudden movements, and give your dog time to recover.
– Work on confidence: Gradual, positive exposure to triggers (with professional guidance if needed) can help your dog build resilience over time.
– Know when to seek help: If your dog’s reactions are frequent or severe, working with a force-free behaviourist can make a huge difference.
Why This Matters
Understanding fight, flight, and freeze helps you see your dog’s behaviour through a lens of empathy—not frustration. With patience and the right support, even the most reactive or fearful dogs can learn to feel safer and more confident in their world.
Fight, flight, and freeze are natural responses to stress in dogs. Recognising these behaviours—and responding with compassion—lays the foundation for real progress and a stronger bond between you and your dog.
