Blog — Threat Threshold

One of the most common recommendations people receive for fearful dogs is to have strangers offer the dog treats in order to “build positive associations.” And while the intention behind this is usually compassionate, it can actually create a tremendous amount of nervous system conflict for many dogs. Especially dogs who already feel wary, pressured, hypervigilant, or uncertain around people. From the outside, it can appear successful because the dog approaches and takes the food. Humans naturally interpret this as comfort, progress, or social willingness. But taking food is not always the same thing as feeling safe. A nervous system...

Many dogs who struggle with reactivity, behavioral changes, or sudden “attitude shifts” are quietly carrying something we don't always see: pain that's being filtered through the nervous system. To understand why pain can hide during activity, show up during rest, and dramatically increase reactivity, we need to talk about three related—but often confused—concepts: Nociception, Stress-Induced Analgesia, and Pain. Nociception is not pain Nociception is the nervous system's process of detecting potential tissue damage or threat—things like excessive pressure, inflammation, chemical irritation, or joint strain—and sending that information to the brain. Importantly: Nociception is the signal Pain is the experience A...

  State Before Story: Creating Autonomic Flexibility In behavior work, we often focus on what a dog is doing and what we want them to do instead. But underneath every behavior is something more fundamental: the dog’s nervous system state. Before there is behavior, there is state. And before there is “story” or interpretation, there is physiology. This is the foundation of autonomic flexibility—the ability for a dog to move fluidly between different nervous system states without becoming stuck in any one pattern. Without this flexibility, behavior becomes rigid. The dog may appear either overly activated and reactive, or shut...

Sentinel Trauma is a one-time learning event which can leave a permanent imprint on the autonomic nervous system.  According to Dr. Stephen Porges, sentinel trauma refers to a single overwhelming event that the body–brain registers as life-threatening. This may take the form of an accident, an assault, or a medical crisis—an experience in which the organism perceives that survival itself is at risk. What makes sentinel trauma unique is that it does not require repetition to take hold. It is what we might call a one-trial learning event—an imprint that occurs instantly, reorganizing the nervous system in the service of...

What Is Biophilic Design? Biophilic design is the practice of incorporating elements of nature into the built environment to strengthen our connection to the natural world. This can include: Natural light Vegetation Water features Natural materials Designs that mimic organic shapes and patterns The goal is simple but powerful: to improve physical, mental, and emotional well-being by bringing us closer to the environments we evolved in. Why It Matters for the Nervous System I was introduced to this concept more deeply through a presentation by Dr. Niki Elliott at a Polyvagal Institute gathering. What stood out most was how biophilic...
