✨ So you put the food down, your dog’s eyes light up and it takes a bite… let’s follow that mouthful on its wild biological journey. This is biology and watch how it puts marketing to shame…This ladies and gentleman is reality.
(This blog has taken just over 3 months to prepare. Please enjoy it. Please understand it)
👄 The Mouth – The First Bite
Whoooosh, the rollercoaster begins. Teeth crunch like turnstiles snapping shut, saliva floods in, coating the food so it can race down the track. In humans, saliva is loaded with enzymes that start breaking food apart right here. In dogs, it’s different. Their saliva is not about chemistry, it’s about physics. It slicks and slides the food down, acting like oil on rails, rushing the bite toward the oesophagus at speed.
The dog’s design is clear: not to chew for minutes like us, but to grab, crunch, swallow and send the ride on. The real chemical fireworks, those enzymes that slice food into usable parts, wait ahead in the stomach and pancreas. The mouth is the cannon launch.
The journey of nutrition begins!!!
If this bite carries weak nutrition, it simply scratches hunger but leaves the body short. If it carries true nourishment, it’s the perfect start to the ride. And if it’s part of an overload, then already the fuse has been lit on trouble to come.
Next stop, the oesophagus, a living chute built for speed and defence.
🌀 The Oesophagus – The Rush Downward
Whooooosh, the bite is hurled into a muscular tunnel, the oesophagus. This is no quiet slide. It squeezes and ripples like a living wave, propelling food with astonishing power straight toward the stomach. Here, speed is everything. A dog was built to gulp meals quickly, sometimes under threat from scavengers or rival pack members. Its instinct.
But the oesophagus is more than a food chute. Its lining is a defensive barrier, working hard to keep bacteria from climbing back up. It relies on your dog drinking enough water to flush it clean and keep it smooth. Neglect hydration and this vital passage suffers in silence.
If this mouthful is weak, it still takes the ride but delivers little. If it is balanced, the oesophagus acts like a perfectly greased track, passing on its passenger with pride. And if it carries overload, the chaos waits below, but the warning signs are already hiding in plain sight.
Next stop, the stomach, a bubbling cauldron of acid where the real battle begins.
🔥 The Stomach – The Acid Cauldron
Whoooosh, the food lands in a bubbling cauldron of hydrochloric acid. And here’s where dogs are different. Their stomach acid is far stronger than ours. It is powerful enough to dissolve bone and destroy bacteria that would leave us hospitalised. This is why a dog can eat things we never could.
🔥🤣 THE GREAT PROBIOTIC FAIRY TALE 🤣🔥
And yet, this is the bit that makes me laugh out loud. TikTok “experts”, Facebook Karen's and would be know it all dog owners would have you believe that powdered probiotics float straight past this acid inferno untouched, drifting like fairy dust on a summer breeze. Really? Here? In this roaring pit of hydrochloric acid that is one supernova punch up, where even bone is stripped apart? Nothing survives without being broken, beaten, or burned to its core.
From here the food is churned into a thick slurry, ready to be released into the small intestine where the real magic of absorption begins.
🌊 The Small Intestine – The River of Absorption
Whoooosh, the slurry spills out of the stomach through the pyloric gate and crashes into a twisting river nearly six metres long in a Labrador. This is the small intestine, the greatest nutrient extraction system nature ever built. Our creators knew organic engineering, they knew it well!
Here bile from the liver and enzymes from the pancreas flood in like carnival workers, breaking down fats, proteins, and carbohydrates into tiny particles. Walls lined with microscopic fingers called “villi” soak up nutrients like sponges, pulling amino acids, vitamins, and minerals into the bloodstream highway.
Every nutrient matters. If this mouthful is rich and balanced, the river glows with life, every cell ahead ready to be nourished. If it is poor, the river runs thin, and the body scrapes by. If it is overloaded, chaos begins, nutrients crashing into each other, disrupting balance and forcing organs to pick up the pieces.
At the end of this wild river, the slurry is split. The best of it heads into the bloodstream highway. The rest drifts onward toward the large intestine where waste will be formed. Dog poo, to you and me.
🔥 The Bloodstream Highway – Life’s Fastest Ride
Whoooosh, the nutrients burst through the walls of the small intestine and leap onto the bloodstream highway. This is no lazy river. It is a supercharged motorway pulsing with life, every surge of the heart pumping fresh energy to every corner of the dog’s body.
The first stop is the liver. Picture a grand control tower rising above the highway, it’s so huge, so magnificent, you just can’t miss it, scanning every single passenger that rushes through.
Proteins, fats, sugars, vitamins, minerals, all checked and sorted with ruthless precision. The liver decides what to store, what to send forward, and what to detoxify. It is a masterpiece of biological engineering, a filter and a factory all in one.
And yet, this is where so many owners fail their dogs. When nutrition is poor, the liver is starved of tools, left to scrape by while the rest of the body pleads for fuel.
When there is overload, the liver is buried under a mountain of excess, storing fat soluble vitamins it cannot easily discard, turning them toxic drop by drop. The dog still wags its tail, still greets you like a hero, while inside the liver whispers under its breath, words that cannot be repeated, as owners brag how healthy their dogs look as they stroke its coat, and the liver continues fighting a battle against biological stupidity it knows it cannot win unless something changes.
If only that lazy owner weighed out the food like a good owner would. Sigh!
This stop should be the beginning of enrichment, the spark of vitality, but too many owners treat their dog as a machine that can handle anything. Add this they say. Try that they are told. TikTok and Facebook echo chambers pour fuel on the fire, all while the truth sits here in the liver. The truth that balance, not imagination is what keeps life flowing.
From here, the nutrients that survive the inspection are dispatched onward to the heart, brain, muscles, skin and every other organ in need. The next phase of the ride awaits.
❤️ The Heart – The Relentless Engine
Boom Boom Boom. The heart never takes a rest, never asks for thanks, never stops. Every drop of nutrition that leaves the liver is thrown into this furnace of power, hurled forward with each beat. Imagine standing beside a jet fuelled rollercoaster car as it rockets out of the station, that is the speed and force of the heart at work.
When the food is lacking, the heart works harder for less. The fuel is thin, the spark is weak, and slowly the rhythm begins to falter. When the food is overloaded, the heart is drowned in chaos, electrolytes unbalanced, blood thickened, blood pressure rising. And yet the dog still greets you with joy, still runs to the door, hiding the discomfort only biology can reveal.
This is no place for guesswork. A weak mind feeding from imagination does not see the damage building here, but the heart feels every poor choice. Day after day, beat after beat, it carries on because that is its role. It does not complain, it simply pushes on until one day it cannot.
From here the highway branches to the brain, where the most delicate and hungry of all organs waits. The ride continues. 🧠
🧠 The Brain – The Command Centre
Whooooosh, the bloodstream now thunders into the most demanding organ of them all. The brain is greedy, it wants first pick, it claims the richest nutrients before any other part of the body gets a chance. It is the conductor of the orchestra, the master switchboard, the seat of thought and instinct. Every wag of the tail, every spark of memory, every flash of joy begins here. The brain rules over all it controls. The brain knows how well its very being is being cared for. The brain judges you!
When the food is lacking, the brain flickers like a light on a faulty wire. The amino acids that build neurotransmitters are short, clarity fades, mood dulls, behaviour changes. The dog may seem forgetful, anxious or restless, but the truth lies not in personality, it lies in missing nutrients.
When the food is overloaded, chaos reigns. Excess minerals thicken the blood, toxins creep into delicate nerve cells, the spark misfires. You may see hyperactivity, confusion, sudden crashes of energy. Owners will say the dog is quirky, unique, even funny, but biology knows it is distress, not character.
Here is where imagination-based feeding is most cruel. Because the brain controls everything, every shortfall or overload here filters down into the body like cracks spreading through glass. The dog still looks at you with love, still trusts you as its hero, but inside the control tower is flickering under strain.
Next the ride plunges towards the muscles, the great engines of strength and play. 💪
💪 The Muscles – The Great Engines
Whooooosh, the bloodstream roars into the muscles, the mighty engines that power every leap, sprint and stretch. Here the nutrients are demanded in bulk, amino acids knit together to repair fibres torn in play, minerals charge the cells like batteries, and vitamins unlock the fuel to keep the whole machine moving. This is where raw strength is born, where stamina is built, where the body proves what has been fed.
When food is lacking, the muscles quietly fade. Fibres cannot rebuild, strength is chipped away, energy drains faster than it should. The dog looks lazy or tired, but the truth is biological weakness, not choice.
When food is overloaded, the muscles swell but with imbalance. Excess proteins ferment into waste, too many minerals disrupt contraction, the very engines clog and strain. Owners smile at their dog’s bulk, calling it powerful, but it is not power, it is a body carrying a burden.
This is where the ride starts to reveal red flags. Owners will still say their dog is thriving, still claim all is well, but a tired step, a slowed chase, or heavy breathing whisper the reality. Biology never lies.
Next the bloodstream races towards the skin and coat, the first place where the chaos inside dares to show itself on the outside. ✨
✨ The Skin and Coat – The Mirror of Health
Whooooosh, the bloodstream bursts into the skin and coat, the outer curtain every passer-by admires. Here the nutrients paint their masterpiece. Amino acids weave keratin for strong fur, fatty acids pour in to make it glossy, minerals spark cell renewal, and vitamins keep the skin supple and alive. When balance is right, the coat gleams, the skin breathes, and strangers smile, saying how healthy the dog looks.
When food is lacking, the coat dulls, hairs snap, skin dries and flakes. The body has already fed heart, brain and muscles, leaving the outer curtain hungry. The sparkle vanishes and the dog itches. This is a whisper from within, a soft cry for more.
When food is overloaded, the coat erupts in chaos. Oils drown follicles, the skin inflames, red patches and sores break through. Owners rush for creams and shampoos, celebrating when the redness hides, never realising they have only shoved the problem back inside. The body always finds another door, another place to vent its frustration.
Here lies one of the clearest red flags. A coat is not decoration; it is the voice of inner balance. And yet, many miss it, proudly stroking softness that masks struggle beneath.
Next the bloodstream surges on, carrying its triumphs and failures alike to the kidneys, the great filters, where every poor decision becomes harder to hide. 💧
💧 The Kidneys – The Relentless Filters
Whooooosh, the bloodstream crashes into the kidneys, those twin gatekeepers working night and day without a pause. Every drop of blood passes through them, filtered with astonishing precision. They sift waste from treasure, toxins from nutrients, and send clean blood rushing back into circulation while the rubbish trickles away as urine.
When balance is right, the kidneys glide with elegance. Electrolytes sit in harmony, moisture levels are perfect, and the waste leaves quietly, unnoticed. The dog feels light, healthy, and in perfect rhythm.
When food is lacking, the kidneys still work, but the blood they filter is thin, underpowered, missing vital building blocks. They cannot pull out what is not there. Slowly, tissues ache, energy fades, and the weakness hides in plain sight, mistaken for laziness or age.
When food is overloaded, the chaos is brutal its cruel. Excess minerals crystallise in urine, stabbing through the urinary tract, creating stones and infections. Proteins and vitamins flood in beyond what the body can use, and the kidneys strain to clear them, scarred by the burden. The dog drinks more, pees more, and yet owners dismiss it as quirks, never realising that cruelty is unfolding quietly under their noses. Driven by poor decisions and usually treats laden with starch!!!
These filters never complain out loud. They simply wear down. And by the time the damage is obvious, it is often too late.
From here, the bloodstream surges forward, racing toward the brain, the command centre, where balance or chaos dictates thought, behaviour, and even personality. 🧠
🎢 The Final Stop – The Exit
From here, the nutrients ride the bloodstream highway, carried first to the liver for processing before being dispatched to heart, brain, muscles, skin, and every other organ. What is not absorbed continues into the large intestine as waste, ready for its final exit. And for those elite owners, this is where the poo bag awaits.
It is not the quantity of poos that matter. Some dogs will go once a day, others five or six. What matters is the consistency and how easy it is to collect. If it is sloppy it points to overload, if it is dry it points to lack of moisture, and above all weigh your dog weekly and record it. Know your dog’s ideal weight and chase it. Increase or decrease by no more than 5g each week to get to perfect. It is what the very best owners do. Those that do not always have excuses. 99.9 percent of them are born inside a lazy mind. And nobody in life is successful with a lazy mind. I have to feel for the dog whose diet is governed by one.
🏁 The Big Truth – One Mouthful, One Lesson
So that is it folks. The journey of a single mouthful.
So, the next time marketing tells you more, the next time you think a fourth pig’s ear will not hurt, remember this. Toxic overload starts with imagination. So, ask yourself what exactly is the thing I am about to feed going to achieve on its journey inside the one creature on God’s earth that thinks I am a hero?
Thank you for getting this far. This blog is an extension of a post I once had on our website. We paid to promote it and saw the numbers. It was started by over 40,000 people.
Only 15 out of 100 got to the end.
It is my belief all of these people deserve a dog.
Because this is promoting factual information and selling nothing.
Marketing always wins in the short term as it harvests weak minds.
Biology keeps quiet and just shows the truth.
Well done for getting here.
Getting here means we can be friends.
⚠️ The Silent Majority – Drowning in Toxic Overload
Around 85 to 90 percent of dogs are overfed. That is not opinion, it is biology written in every vet clinic waiting room. Most of these dogs wag their tails, look healthy enough to a blind eye, and keep eating because they trust their hero. Yet inside, their organs are fighting a daily storm, shovelling away last night’s overload, last week’s excess, last month’s chaos.
And still, with blind naivety, the same handful of food is poured in again. Owners convince themselves it shows love. They convince themselves the dog is thriving. But biology never accepts excuses. Organs cannot lie. Quiet damage builds. Quiet suffering deepens. Quiet cruelty continues.
So, stop and think. If your dog’s body is already struggling to clear the mountain of excess you gave it yesterday, what exactly do you think today’s overload will achieve? Or that extra bone broth Karen said to add on the internet? Because the truth is simple. It achieves nothing but more suffering for the one creature on this earth that calls you hero.
Thank you for reading my very best ever blog.

Hi Richard. Great read! Even if parts read like a horror story 😂.
I know our dog Olly is reaping the rewards of your hard work. So thank you.
This information is totally relatable to my dog. I can’t tell you the issues we have had with Alfie, from raw to cooked, wet food to kibble and everything in between. The “exit”.is the best and most consistent we have had. Alf will eat anything so that has never been the problem, it’s the “before” the exit that we have had the most problems with. The advice and information have been invaluable, simple really, stripped right back, common sense. We understand that it all takes time to for our dogs to recover from what we have been feeding and amounts, follow the process, we will get there in the end.
