The Nervous System of Dogs: How Modern Civilization Affects It

The Nervous System of Dogs: How Modern Civilization Affects It

How Exploring Nature and Biology Brings Us Closer to Understanding Our Dogs

When we observe nature, it is difficult not to notice one fascinating fact. Whether we are talking about a wolf in the forest, an eagle on a mountain peak, a dolphin in the ocean, or an ant beneath the soil, every living being appears to know exactly where it belongs. Its body, nervous system, behavior, and way of life have evolved over millions of years in harmony with the environment in which it lives. Nature did not create perfect beings; it created beings capable of adaptation.

On the other hand, there is the human being: the only species that did not merely adapt to the world around it, but developed the ability to reshape the world according to its own needs. Humans can build cities in deserts, illuminate the night as if it were day, redirect rivers, control indoor temperatures, and produce food thousands of miles away from where it originated. No other species on Earth possesses such power.

Yet this is precisely where one of nature’s greatest paradoxes begins. The more humans mastered their environment, the less they seemed able to master themselves. Never in history have we had more comfort, choices, or opportunities to decide where we live, what we eat, whom we build relationships with, and how we organize our lives. At the same time, there has never been more anxiety, chronic fatigue, sleep disturbances, emotional exhaustion, and feelings of inner instability. Consequently, it seems as though we conquered the external world while losing connection with our internal one.

This may sound provocative, but sometimes it seems that humans are the only species that systematically creates conditions that reduce the quality of its own life. I am not speaking only about wars, pollution, or social conflict. I am speaking about everyday decisions: the way we eat, sleep, work, build relationships, and shape our environment. We have the freedom to choose, yet very often we choose what moves us further away from balance. Therefore, in this downward spiral, humans bring with them all those they love: their families, their children, and the animals with whom they share their lives. That is why this is not only a story about humans; it is also a story about dogs.

The Impact of the Environment on the Dog’s Nervous System

Many of the problems we attribute to dogs may actually be consequences of the environment we have created.

For most of their evolutionary history, dogs lived in a world that was relatively predictable. The cycles of day and night were clear. Scents came directly from nature. Sounds generally carried meaning related to survival. Their biological systems evolved within an environment that was far simpler than the world we inhabit today.

The modern dog, however, no longer lives in nature. As we have discussed before, mineral balance within the body is deeply connected to nature, yet today’s dog spends most of its life within human civilization. Dogs live surrounded by traffic, screens, artificial lighting, noise, chemicals, constantly changing schedules, and an enormous amount of stimulation that the nervous system of dogs must process every single day.

MODERN STIMULATION AND THE CHALLENGE OF MAINTAINING HOMEOSTASIS.

Ironically, many of the behavioral problems we now attribute to dogs may not have originated in dogs at all. Perhaps they originated in the artificial environment we created around them. We frequently talk about anxious dogs, reactive dogs, and overly sensitive dogs. However, far less often do we ask whether the nervous system of dogs is simply trying to adapt to living conditions that no generation before it ever experienced.

To understand why this matters, we must return to one of the most important principles in biology: homeostasis. Simultaneously, we must recognize that when it comes to the nervous system of dogs, homeostasis serves as the foundation of survival, balance, and inner peace in an increasingly chaotic world.

Ultimately, that balance will be the subject of the next column.

Why Dogs Become Anxious: The Unconscious Mistakes Owners Make

Why Dogs Become Anxious: The Unconscious Mistakes Owners Make

Anxiety in dogs is not random and it does not appear by accident. It is built through daily dynamics, tone of voice, and the emotions we express—or even more, the emotions we suppress. Many owners believe they have done everything “by the book,” yet they wonder why dogs become anxious. The answer almost never lies in the dog itself, but in what the dog feels from us.

The Dog Listens to the Heart, Not the Words

Imagine a young wolf in nature. If his mother panics, he concludes the world is dangerous. Your dog does the same. When an owner is emotionally unstable or insecure, the dog doesn’t listen to words—the dog listens to the heart, the breathing, and the body language. If the human feels unsafe, the dog forms an anxious pattern.

Common Mistakes That Lead to Anxiety

To understand why dogs become anxious, we must look at how we treat them:

  1. Treating the Dog Like a Child: Phrases like „You are my everything“ place an emotional burden on the dog. They feel responsible for your state, a weight no dog can carry.

  2. Suppressed Anxiety: You might say you aren’t anxious, but the dog feels what you hide. Suppressed fear transfers directly to them.

  3. Overprotection: Constant „careful“ warnings signal that the world is a dangerous place where even you cannot protect them.

  4. Inconsistent Boundaries: When rules change daily, the dog loses the structure they need for peace.

When we impose our emotions on a dog, we create a burden they don’t know how to carry.

 

How to Help a Dog Live a Stable Life

A dog does not need emotional worship; they need a stable owner. To resolve why dogs become anxious, provide:

  • Calm energy and routine

  • Clear rules and boundaries

  • Space for the dog to simply be a dog

  • The feeling that someone else is responsible for safety

When the owner is centered, the dog no longer feels the need to take over that role, and anxiety disappears as a natural consequence.


At Sasha Riess, we believe that a stable dog starts with a centered owner. By understanding why dogs become anxious, you can stop being an emotional burden and start being a calm guide, leading your pet back to pureloveandharmony. Discover more:Linktree Sasha Riess

The Dog Only Wants to Go Outside When Dressed: A Dog Who Refuses to Go Out Without Clothes

The real issue isn’t temperature. Dogs have a completely different system of thermoregulation from humans — they don’t sweat like we do. Their fur creates a thin layer of air between the skin and the outer coat, forming a natural “insulating bubble.”

When you take a dog outside, that thin layer of air warms him in winter and cools him in summer. That’s why shaving dogs too short — especially in the summer — can cause major problems: it prevents them from maintaining that protective air layer. Even short-haired dogs, like Pinschers or Boxers, have this natural protection.

Shedding and the Protective Role of Hair

Short-haired dogs shed frequently. Their coat’s life cycle lasts about 21 days, while the undercoat renews every one to two weeks. Within three weeks, the entire coat regenerates. Even short hair lifts slightly — often invisible to the human eye — creating a thin air space that protects the dog from the cold in winter and from overheating in summer.

The Real Cause: Anxiety

The dog described in the question is not reacting to cold but to dog anxiety — deep-seated anxiety rooted in his relationship with the owner. When a dog obeys out of fear rather than trust, he feels responsible for protecting his owner in the car, on walks, or from other people. He lives in a constant state of alertness, trying to control a world that feels too big for him. Through this behavior, the dog is showing that he doesn’t believe his human can keep things safe.

Signs of Dog Anxiety

It wouldn’t be surprising if such a dog also:

  • Pulls on the leash,

  • Barks excessively at people or doorbells,

  • Refuses to stay home alone,

  • Loses appetite,

  • Shows constant stress-related behaviors.

Eventually, under the pressure of chronic stress, the dog’s body begins to break down.

Dressing Is Not the Solution

Dressing a dog has nothing to do with the cold. Think about what happens when we humans are nervous — our stomach tightens. This is because the vagus nerve connects the digestive organs with the heart and the parasympathetic nervous system.

Dogs have the same mechanism. When fear activates this nerve, it triggers physical symptoms — and in winter, these reactions become more visible. Winter awakens the ancient instinct for survival, where the body prepares for scarcity and danger.

How to Help Your Dog

Dogs that can’t handle the emotional tension of their environment often take on the family’s stress. Most emotional “breakdowns” in dogs happen in winter because we fail to prepare their nervous systems.

Support your dog through:

  • A proper diet,

  • The use of prebiotics and probiotics,

  • Regular parasite cleansing,

  • Following the Harmony Manual that helps establish healthy boundaries.

When this balance is restored, the dog can finally relax — living as a dog should: calm, trusting, and ready to follow you everywhere. This is the goal of a healthy human dog relationship.
