  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...

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...

Why Chewing Matters for Dogs Many thanks to Joy Eriksen for sharing this article with me. Joy is a CSAN (Certified Species Appropriate Nutritionist) and a great resource if you need guidance with raw feeding. The article highlights something simple—but incredibly important: Chewing isn’t just a pastime for dogs. It’s a biological need. More Than Just a Habit We often think of chewing as something to manage or redirect—especially when it shows up as unwanted behavior. But when we look deeper, chewing serves essential functions for both physical and emotional health. Denying dogs appropriate outlets to chew doesn’t just create...

What Is Leash Reactivity, Really? Leash reactivity is one of the most commonly discussed behavior challenges in dogs, but it is also one of the most misunderstood. People often use the term as a diagnosis or label for barking, lunging, growling, or over-excited behavior on leash. While these are the visible expressions, they are not the root of the issue. Leash reactivity is not a single behavior pattern, and it is not a personality trait. It is a nervous system response that emerges under specific conditions. To understand leash reactivity, we have to look beyond what the dog is doing...

  Why Temperament Matters and How It Shapes Personality When we talk about dog behavior, we often default to describing what we can see: whether a dog is friendly, reactive, confident, sensitive, or anxious. These descriptions are usually grouped under the idea of “personality.” But personality does not emerge randomly. It is built on a deeper biological foundation: temperament. Temperament is the underlying template that shapes how a dog is likely to respond to the world. It influences thresholds for arousal, sensitivity to threat, intensity of drive, and the speed at which the nervous system activates or recovers. Personality then...
