Canine Evolutions

07/31/2025

In my decades of work no concept has proven more pervasive, nor more fundamentally misleading, than that of "distraction." It is the universal scapegoat for a lapse in connection, the label we apply when a dog’s attention strays from our intended path to a squirrel, a scent, or a sound on the wind. We frame it as a failure of focus, a moment of willful disobedience. But after countless hours observing the intricate dance between human and canine, and immersing myself in the neuroscience that governs it, I have come to see this interpretation for what it is: a profound delusion. The dog that turns away is not broken, nor is he defying you. He is, in fact, operating flawlessly according to a biological imperative far more powerful than our desire for compliance.

This article is an invitation to join me in a paradigm shift—one I call The Salience Shift. We will move beyond the flawed language of distraction and into the precise world of motivational neuroscience, where we learn that attention is a currency allocated only to what the brain deems most salient, or motivationally relevant. Your dog is not ignoring you; he is making a valid neurological choice to engage with a stimulus that has, in that moment, won the auction for his attention. Our task, then, is not to suppress the world, but to change our place within it. We will journey through the architecture of the canine mind to answer the most critical question in training: not "How do I stop my dog from being distracted?", but "How do I become the most salient, rewarding, and engaging phenomenon in my dog’s world?

In his decades of work as a cynologist, Bart De Gols has found no concept more pervasive, nor more fundamentally misleading, than that of "distraction." He identifies it as the universal scapegoat for a lapse in connection—the label handlers apply when a dog’s attention strays from an intended path to a squirrel, a scent, or a sound on the wind. This behavior is often framed as a failure of focus or a moment of willful disobedience. But after countless hours observing the intricate dance between human and canine, and immersing himself in the neuroscience that governs it, de Gols has come to see this interpretation as a profound delusion. The dog that turns away is not broken, he argues, nor is it defying its handler. It is, in fact, operating flawlessly according to a biological imperative far more powerful than the desire for compliance.

This podcast is an invitation to explore a paradigm shift de Gols calls The Salience Shift. The episode moves beyond the flawed language of distraction and into the precise world of motivational neuroscience, where attention is understood as a currency allocated only to what the brain deems most salient, or motivationally relevant. According to de Gols, a dog isn't ignoring its handler; it is making a valid neurological choice to engage with a stimulus that has, in that moment, won the auction for its attention. The task for handlers, then, is not to suppress the world, but to change their place within it. Listeners will journey through the architecture of the canine mind to answer the most critical question in training: not "How do I stop my dog from being distracted?", but "How do I become the most salient, rewarding, and engaging phenomenon in my dog’s world?"

Step into the fascinating world of canine consciousness in this episode of The Canine Deep Dive, where we venture beyond wakeful behavior and explore what happens when our dogs close their eyes and drift into slumber. In this compelling episode, In Dreams They Run, Cynologist Bart de Gols unravels the neuroscience of sleep and the mystery of canine dreaming, blending cutting-edge research with philosophical curiosity to better understand the minds of our four-legged companions.

Drawing on over thirty years of behavioral science, de Gols guides listeners through the various stages of the canine sleep cycle—light sleep, slow-wave sleep, and the elusive REM stage where dreams unfold. But this isn’t just about rest; it’s about what these stages reveal. What does it mean when your dog twitches in their sleep? Are they chasing rabbits through imagined fields? Are they revisiting moments of joy—or trauma—from their waking life? And more importantly, what does this tell us about memory, emotion, and the inner world of dogs?

We explore scientific findings from comparative neurology that confirm dogs, like humans, exhibit the telltale brainwave patterns associated with dreaming. But dogs don’t just dream—they process experiences, reinforce learned behaviors, and even rehearse social interactions while they sleep. This podcast goes far deeper than simple curiosity. It challenges our assumptions about cognition in animals and compels us to reconsider how dogs experience the world—from learning new commands to recovering from trauma.

Bart introduces listeners to a concept he calls cognitive anchoring, where dream activity in dogs may serve to emotionally stabilize and neurologically consolidate both positive and negative life events. Sleep, then, becomes not only a biological need but a form of emotional hygiene. This lens is particularly relevant in behavioral rehabilitation cases, where the role of restorative sleep is often underestimated or overlooked.

Listeners will also learn about how age, breed, and training impact dream frequency and sleep quality. Puppies, for example, dream more frequently as their brains wire and rewire during development. Senior dogs may dream with less frequency, but show signs of deep-rooted memory recall. Herding breeds and working dogs tend to have highly vivid REM phases due to their active daily engagement and stimulus-rich environments. These insights open the door to more ethical and compassionate approaches to canine care, emphasizing the importance of sleep environments, routines, and emotional safety.

This episode also touches on the poetic and soulful side of dreaming. Bart reflects on the silent companionship of dogs during the night, imagining the stories they revisit in their sleep—the dogs they once met, the trails they followed, the humans they loved. With evocative language and scientific rigor, he paints a picture of the canine mind as not just instinct-driven, but richly textured with emotion, memory, and narrative.

I often return to a single image when trying to explain the perceptual divide between humans and canines: the tiger. Not just any tiger, but the now widely circulated split-image that compares how we, as trichromats, perceive a tiger’s bold orange coat against lush green vegetation versus how a dichromatic animal—like a deer, or a dog—would see it. To us, the tiger is a radiant flame in the forest: bright, striking, almost impossible to miss. But to a dichromat, the orange pigment collapses into a hue that closely resembles the background. The predator disappears. Camouflage succeeds.

This image encapsulates the fundamental truth that perception is not reality—it is a neurological construct shaped by the hardware of the sensory system and the software of the brain. The same object, the same environment, the same stimulus can be perceived radically differently depending on the biology of the observer. When it comes to dogs, this perceptual divergence has enormous implications—most of which remain dangerously underestimated by the average trainer or owner.

Dogs, like the tiger’s prey, are dichromatic. Their retinas lack the long-wavelength-sensitive cones that allow humans to differentiate between red and green. What this means in practice is that where we see a spectrum rich in reds, oranges, and bright greens, the dog sees a more muted world composed primarily of bluish-violets, greys, and yellows. A toy that appears bright red to us does not “pop” against a green lawn in the dog’s perceptual world—it fades into a background of similarly toned visual noise. This isn’t a subjective opinion—it’s a measurable fact of retinal anatomy and cone distribution.

But vision is not merely about color. It is about what grabs attention, what is meaningful, and ultimately, what creates emotional responses. The visual system is directly connected to deep emotional processing centers in the brain—most notably, the amygdala, which is responsible for assessing threat and triggering fight-or-flight responses. A dog doesn’t simply “see” a moving object—its brain evaluates that object for salience, novelty, and safety. If the visual signal lacks clarity or consistency—if it flickers, looms suddenly, or carries poor contrast—it’s more likely to trigger a primal, reflexive reaction rather than a thoughtful, cognitive response.

That’s why understanding how dogs perceive visual input is essential to creating environments and training protocols that don’t overwhelm or confuse, but instead foster clarity, calmness, and engagement. I often say that behavior is not just learned—it’s filtered through perception, and perception is rooted in neurology.

Let me give you a real-world example of how this knowledge is translated into meaningful design: the Chuckit ball. Most people assume that the iconic Chuckit ball—with its distinctive orange body and blue stripe—is designed for human aesthetics. The truth is far more scientific. The orange color, while attractive to human buyers, is almost invisible to the dog once thrown into a green or brown environment. On its own, the orange would blend in—just like the tiger in the dichromatic forest. But the designers at Chuckit, likely advised by veterinary vision science consultants, added a blue stripe across the ball. This was not decoration—it was contrast engineering.

Blue, as one of the few hues dogs perceive vividly, creates a stark edge that the dog can track visually while the ball is in motion. It introduces perceptual boundaries. It makes the object “stand out” not to us, but to them. This visual differentiation helps the dog stay engaged with the chase. It improves retrieval success. It minimizes frustration. And, perhaps most importantly, it builds confidence—because the sensory world is suddenly more navigable.

When I explain this to clients, it often opens up an entirely new way of thinking. A dog missing a recall cue or failing to find a toy isn’t necessarily inattentive or stubborn. They may simply not see what we think they see. The fault lies not in the dog’s behavior, but in our assumptions about shared perception. The addition of that simple blue stripe on a toy represents an entire philosophy I advocate for in training: meet the dog where they are, not where we want them to be.

This becomes especially critical when working with dogs that show reactivity, fear, or hypervigilance. Their visual system, optimized for motion and edge detection more than color, is constantly scanning for threats. Sudden movement in the periphery—what we might filter out as irrelevant—can be processed as a significant environmental change. A jogger in dark clothing emerging from behind a tree can appear, in their visual field, as a looming shadow-likeBart De Golsbined with previous trauma or lack of socialization, such stimuli easily trigger limbic system activation, leading to barking, lunging, or flight responses. If we don’t understand that the visual appearance of that jogger is qualitatively different to the dog, we misinterpret the reaction as bad behavior rather than what it truly is: a neuroethological response to a perceived threat.

In training, I always consider what I call the threshold of perceptual ambiguity. The more ambiguous or uncertain a visual stimulus is to the dog, the more likely it is to be processed with suspicion or fear. High-contrast, slow-moving, clearly outlined figures tend to be processed more cognitively. Sudden, low-contrast, erratic figures tend to push the dog into a primal mind state, where thinking shuts down and reflex dominates. This understanding allows us to shape training environments with careful control over visual load: clothing colors, lighting conditions, distance to stimuli, and motion patterns. It is not merely kindness—it is neuroscience-informed efficiency.

So when I see that Chuckit ball fly through the air, its blue stripe slicing across the landscape, I don’t just see a toy. I see a rare example of human design aligning with canine perception. I see cognition being made possible through perceptual accommodation. I see a product designed not for the purchaser, but for the user—the dog. And I wish more of the dog training world would follow suit.

Because the lesson of the tiger is not about stripes. It’s about assumptions. The assumption that others perceive as we do. The assumption that behavior is always volitional, rather than reflexive. The assumption that if a dog doesn’t respond, it’s a training failure—when in fact, it may be a perception mismatch. If we want to build ethical, relationship-based training systems, we must begin by discarding our anthropocentric view of the world. We must replace it with a sensory empathy rooted in biology and respect.

Our dogs are not red-green blind. They are not defective. They are different. And when we train with that difference in mind, something beautiful happens: we stop commanding behavior, and we start cultivating connection.

What do classical music, the ocean’s twilight zone, off-road motorcycles, and dog training have in common? For cynologist Bart De Gols, the answer is simple: connection without words.

In this candid episode, listeners are invited into the remarkable life of Bart De Gols—a man whose journey through music, deep-sea exploration, and the canine mind reveals a profound philosophy rooted in empathy, trust, and presence. Bart’s story begins in Aalst, Belgium, where as a child he trained in trumpet, piano, and organ. That early devotion to classical music didn’t just shape his discipline—it refined his ear for the rhythms and subtleties that now guide his work with dogs.

In 2004, Bart led a joined Andi and National Geographic expedition to the Bunaken twilight zone—a mysterious region of the ocean between light and darkness—diving into the twilight zone to document the elusive Coelacanth fish. The intense focus, silence, and nonverbal coordination demanded in those dives left a lasting imprint on his understanding of communication and trust—principles he would later carry into the world of dog behavior.

After medical retirement from diving in 2005, Bart turned fully to cynology. But the spirit of adventure never left him. In recent years, he’s embraced off-road motorcycling, challenging himself across rugged terrain and translating those lessons directly into his training methods: break challenges into manageable steps, stay calm under pressure, and never underestimate the power of persistence.

Throughout all these pursuits, Bart’s philosophy has remained consistent—real growth begins where words fall short. In his educational series From Tyrant to Teacher and throughout his work, Bart teaches that every dog has a “unique music” of their own, an internal world that deserves to be heard, not silenced. His approach rejects domination in favor of collaboration, guiding struggling dogs through compassion, not control.

This episode explores how Bart’s diverse life experiences—across music halls, ocean depths, and dusty trails—inform his deeply human, deeply spiritual approach to the human-canine bond. For Bart, working with dogs isn’t just a job—it’s a sacred mission.

In this powerful episode 7 of The Canine Deep Dive, we explore the mind of the dog through the lens of cynologist Bart de Gols and his article “Human Decoders.” Dogs are more than just companions—they are highly sensitive interpreters of human behavior, capable of detecting subtle emotional shifts, body language cues, vocal tone, and even hormonal changes. Over thousands of years of co-evolution, they have developed an almost psychic ability to read us—not through magic, but through biology, behavior, and deeply embedded neural adaptations.

This episode unpacks the science behind this extraordinary interspecies connection. While many animals can respond to human signals, dogs are uniquely attuned to us. Research shows that dogs outperform even chimpanzees in understanding human gestures like pointing and gaze-following. This isn’t just learned behavior; dogs are born into a world shaped by human communication. They pay close attention to ostensive cues—signals that indicate communicative intent, such as eye contact, changes in vocal pitch, and body orientation. These cues trigger cognitive shifts in the canine brain, activating regions responsible for empathy, attention, and social processing.

We explore how dogs don’t simply react to what we do—they resonate with how we feel. Dogs exhibit mirror-like brain responses to human emotions. This is called motor resonance, and it allows them to synchronize their behavior with ours in real time. Functional brain studies show that dogs respond to human laughter, crying, and even silence by adjusting their own emotional states. They aren’t just watching us—they’re feeling with us.

Olfaction plays a central role in this decoding ability. Dogs can detect chemical changes in our bodies when we’re anxious, fearful, excited, or ill. Through scent, they can interpret our internal states with astonishing precision—explaining why dogs can be trained to detect seizures, blood sugar changes, or PTSD episodes before they happen. Combined with visual and auditory cues, this makes dogs true multisensory interpreters of the human condition.

But beyond science, there is a poetic truth: dogs understand us. When we meet their eyes, the oxytocin loop is activated in both species—creating a feedback cycle of trust, bonding, and emotional regulation. This is the same hormone responsible for parent-infant bonding. What looks like affection from your dog is actually a profound biological link rooted in evolutionary survival and emotional safety.

Cynologist Bart de Gols challenges us to look beyond obedience and into relationship. A dog’s ability to decode us should reshape how we train, communicate, and live alongside them. When we rely too heavily on commands and forget the emotional context in which those commands exist, we miss the essence of our relationship. Dogs don’t just respond to what we say—they respond to who we are in that moment. Our intentions, energy, and emotional coherence all shape their responses.

This episode invites you to rethink your dog—not as a subordinate, but as a sophisticated social partner whose brain is wired to understand you. Whether you’re a professional trainer, behaviorist, or passionate owner, you’ll come away with a deeper respect for what it truly means to be known by a dog.

Join us for a profound and scientifically grounded conversation about one of the most unique relationships in the natural world. Your dog is decoding you—moment by moment, gesture by gesture, breath by breath. The question is: are you paying attention?

Aggression in dogs is rarely “random.” Behind every growl, snap, or bite lies a complex network of biological, emotional, and environmental factors. In this episode of The Canine Deep Dive, we unravel the science of the “angry brain” and explore the true roots of aggressive behavior in dogs—beyond myths, assumptions, and quick-fix labels.

Dogs may be domesticated, but they still carry ancient instincts shaped by survival. In the wild, aggression was never about chaos—it was strategic. It defended territory, settled conflict, and protected resources. Most displays were ritualistic, meant to avoid actual harm. But in today’s homes, that same wiring can backfire, especially when misunderstood or ignored.

This episode examines the three primary neural pathways that give rise to aggression:
• Reactive (fear-based) aggression – triggered by perceived threats or overwhelming stimuli.
• Proactive aggression – calculated and purposeful, used to gain access to food, space, or control.
• Predatory aggression – driven by hardwired hunting sequences, often misread as “play” or “random.”

We explore how brain regions like the amygdala, hypothalamus, and periaqueductal gray orchestrate aggression and how the prefrontal cortex—the brain’s “braking system”—regulates or fails to regulate it. Genetics also play a powerful role. Some breeds were intentionally developed for traits tied to aggression, such as territoriality, guarding, or prey drive. These aren’t flaws—they’re functional adaptations—but without proper guidance and context, they can become liabilities.

Hormones, life experiences, trauma, and even diet can further modulate aggression thresholds. A lack of socialization, physical activity, or mental stimulation doesn’t just create boredom—it can foster neurochemical instability. Dogs under chronic stress may appear fine until one small trigger pushes them over the edge.

Rather than labeling a dog as “aggressive,” we ask: What’s happening inside the brain and body? Understanding this is essential for real, lasting change.

We also touch on:
• How early experiences shape brain development and reactivity
• Why punishment can worsen aggression by bypassing the cognitive brain
• How age, pain, and neurological decline can shift a dog’s tolerance over time
• The difference between management and true behavior modification

As science advances, we’re entering a new era of behavior therapy—one that blends neuroscience, genetics, behaviorism, and training. The goal isn’t to suppress aggression but to understand it and redirect it.

This conversation isn’t just for professionals—it’s for anyone who’s ever asked, “Why did my dog do that?” The answer isn’t simple, but it’s knowable. And that knowledge is the first step toward safer, more connected lives with our dogs.

Episode 5 of The Canine Deep Dive explores one of the most visually striking yet behaviorally complex traits in the dog world: blue eyes. Often admired for their piercing beauty, blue eyes in dogs carry more than just aesthetic value—they may also serve as a window into the genetic and neurological makeup of the animal. This episode delves into the intricate relationship between canine eye color, genetics, sensory perception, and behavior, unraveling a puzzle that is as scientifically rich as it is emotionally resonant.

At the center of this exploration are two compelling case studies: Tater Tot, a Miniature Australian Shepherd with merle coloring, and Finnley, a Catahoula Leopard Dog. Both dogs exhibit severe anxiety, reactivity, and sensitivity to light and sound. Their behaviors, often misunderstood as stubbornness or aggression, are examined through the lens of genetic predisposition. Tater Tot squints and blinks in bright light, revealing discomfort likely linked to sensory overload and vision irregularities. Finnley, on the other hand, displays intense stress responses, coupled with an unusual red pigmentation in one eye under duress, signaling possible vascular or neurological changes. These stories illustrate that behavior is rarely random—it is often the external expression of deeply rooted biological factors.

The episode outlines three primary genetic mechanisms responsible for blue eyes in dogs, each with potential implications for health and behavior. The first is the merle gene, known for producing mottled coat patterns and blue eyes in breeds like the Australian Shepherd. This gene doesn’t just affect appearance; it can influence pigmentation in the inner ear and eyes, leading to compromised sensory processing. The second mechanism is a mutation in the ALX4 gene, found in many Catahoula Leopard Dogs, which affects melanin distribution in the iris and potentially in other sensory tissues, contributing to hyper-reactivity. The third involves a general reduction of melanin in the iris, which can occur independently of breed-specific mutations and is associated with increased light sensitivity.

Through this genetic lens, the episode draws a compelling connection between physical traits and behavioral tendencies. Blue-eyed dogs may have lower thresholds for sensory stimuli, making them more prone to stress, reactivity, and anxiety. This isn’t a flaw but rather a neurological reality shaped by their DNA. Training and behavioral support must account for these underlying sensitivities, shifting the focus from obedience to understanding. Rather than labeling these dogs as difficult or untrainable, the episode advocates for customized training environments—ones with reduced sensory input, careful socialization, and a keen awareness of the dog’s threshold for stress.

Listeners are invited to rethink how they interpret canine behavior, especially in breeds that carry the genetic blueprints for both striking appearance and unique neurological wiring. Blue eyes, it turns out, may be more than just a quirk of nature—they may be indicators of how a dog experiences the world, both physically and emotionally. Episode 5 ultimately challenges conventional thinking by suggesting that what we see in a dog’s eyes is not just reflection or color, but biology whispering truths about perception, discomfort, and resilience.

This installment of The Canine Deep Dive offers a nuanced and science-backed perspective on a topic rarely discussed in mainstream dog training. It is a compelling call to look beyond the surface and understand the silent stories carried in every glance from a blue-eyed dog.
