For decades, dog parents have been told that their beloved companions are just domesticated wolves, implying that they should eat and behave like their wild ancestors. However, modern scientific research paints a different picture—one that challenges outdated beliefs and highlights the true evolutionary journey of dogs.
📌 The Evolutionary Link: From Miacis to Modern Dogs
Dogs, wolves, bears, and raccoons all trace their origins back to a common ancestor—a group of carnivorous mammals known as Miacis, which lived around 65–55 million years ago.
🔎 Key Evolutionary Events in Canine History: ✅ Miacis (65–55 million years ago): The ancient carnivore that gave rise to canines, bears, and raccoons. ✅ Pleistocene Wolf (~10,000–13,000 years ago): A now-extinct species that was an ancestor of both modern wolves and domestic dogs. (Read Study) ✅ Genetic Split Between Wolves & Dogs (27,000–40,000 years ago): Research confirms that dogs became a distinct species long before domestication began, becoming a distinct species with different nutritional requirements. (Read Study)
📌 Why does this matter? Because genetic divergence means that dogs have developed distinct biological, digestive, and nutritional needs, separate from those of wild wolves.
📌 The Science of Canine Domestication & Diet Evolution
📌 The genetic split between dogs and wolves happened between 27,000 and 40,000 years ago. That’s tens of thousands of years of separate evolution—enough time for significant biological changes to occur, particularly in digestion, metabolism, and behavior.
💡 Key Differences Between Dogs & Wolves:
✅ Dogs Have Adapted to Digesting Starches 📌 A groundbreaking 2013 study published in Nature revealed that modern dogs have multiple copies of the AMY2B gene, which allows them to efficiently digest starches and carbohydrates—something wolves lack.
Dogs have up to 30 copies of the start-digestive gene Amy2B, similar to humans, when wolves only have two.(Read Study)
✅ Dogs Have Different Digestive Enzymes 📌 Compared to wolves, dogs produce significantly more amylase and maltase, the enzymes responsible for breaking down plant-based foods.
✅ Domestication Changed Dogs' Nutritional Needs 📌 As dogs evolved alongside humans, their diets naturally shifted to include grains, legumes, fruits, and vegetables as main ingredients—a key distinction from wolves, who rely primarily on meat.
📌 Wolves are obligate carnivores, but domestic dogs are facultative omnivores, meaning they can thrive on a variety of foods, including plants.
📌 What Does This Mean for Your Dog’s Diet?
📌 Feeding a dog like a wolf ignores thousands of years of evolution. Despite marketing claims from raw food brands and pet food companies, modern domestic dogs do not require a diet that mimics that of a wolf.
🔎 Scientific research overwhelmingly supports the fact that dogs can thrive on a plant-based diet as long as it is nutritionally complete. (Read Study)
📌 The idea that dogs must eat meat is a myth based on outdated science.
💡 Instead of focusing on “wolf-like” diets, dog parents should prioritize: ✅ Fresh, whole, nutrient-dense foods. ✅ Anti-inflammatory, disease-preventing ingredients. ✅ A balanced diet that meets all nutritional requirements, regardless of source.
📌 As a Canine Nutritionist, I create evidence-based meal plans tailored to your dog’s unique needs—based on science, not outdated myths.
Why Wolves Aren't Obligate Carnivores:
1️⃣ Wolves Consume Plant Matter in the Wild
Studies on wolf scat (feces analysis) reveal that wolves regularly eat berries, fruits, grasses, and even the partially digested plant matter found in the stomachs of their prey.
In summer and fall, when prey is scarce, wolves have been observed eating blueberries, apples, and other seasonal fruits.
Research on North American gray wolves has found up to 83% plant material in their diet during certain seasons! (Source)
2️⃣ Wolves Can Digest Carbohydrates
While wolves prefer animal protein, they can digest starch and fiber to some extent.
A study comparing wolf and dog genetics found that while dogs have more copies of the AMY2B gene (which helps digest starch), wolves still possess some ability to digest carbohydrates (PubMed Study).
Wolves also eat the stomach contents of herbivorous prey, which includes partially digested plant material, suggesting they gain nutrients from plant-based foods.
3️⃣ Evolutionary Adaptability
Wolves are opportunistic feeders—meaning they will eat whatever is available to survive.
During harsh winters or when prey is scarce, wolves scavenge and consume roots, grasses, and fruits to sustain themselves.
4️⃣ Social Carnivores vs. Obligate Carnivores
Obligate carnivore must eat meat to survive because they lack enzymes needed to process plant nutrients efficiently.
Wolves, however, can survive on plant-based foods when necessary, making them facultative carnivores.
📌 Bottom Line:
🟢 Wolves are NOT obligate carnivores because they can digest plant materials and adapt their diet when necessary. While they thrive on meat, they have been observed consuming fruits, berries, grasses, and other plant-based foods both in the wild and in controlled studies.
📌 Final Thoughts: Are Dogs Really Wolves?
📌 🚫 No—modern dogs are NOT wolves. 📌 ✅ They are a distinct species with unique nutritional needs. 📌 🚫 Feeding them like wolves ignores thousands of years of evolution. 📌 ✅ A fresh, balanced, whole-food diet is the best way to support long-term health.

One of the most common misconceptions about dogs is that they are strict carnivores, requiring a diet composed primarily of meat. However, scientific research and evolutionary biology tell a different story—one that highlights dogs as omnivorous scavengers, capable of thriving on a wide variety of foods, including plant-based ingredients.
📌 The Science: Dogs Are Omnivorous Scavengers, Not Carnivores
📌 The National Research Council of the National Academies has classified domesticated dogs as omnivorous scavengers, meaning they have evolved to consume and digest both plant and animal-based foods. (Read Study)
🔎 Key Evolutionary Adaptations That Support an Omnivorous Diet in Dogs:
✅ Digestive System Adaptations 📌 Unlike obligate carnivores, dogs have evolved to digest and utilize carbohydrates efficiently. They possess higher levels of amylase, an enzyme that breaks down starches, which is nearly absent in true carnivores. (Read Study)
✅ Tooth Structure Changes 📌 Compared to wolves, dogs have shorter, more compact teeth, better suited for crushing plant materials rather than just tearing flesh. (Read Study)
✅ Metabolic Adaptations 📌 Dogs can derive essential nutrients from plants, including vitamin A from beta-carotene, something wolves and obligate carnivores cannot do. (Read Study)
📌 Bottom line: Over thousands of years, dogs have adapted to thrive on an omnivorous diet, including plant-based foods, rather than requiring a meat-exclusive diet.
📌 Wolves: Not Even They Are True Carnivores
📌 Even wolves—which share a common ancestors with modern dogs—are not strict carnivores. Despite their reputation as top predators, wolves are classified as facultative carnivores, meaning they primarily eat meat but also consume plant matter when necessary for nutrition and digestive health.
🔎 Surprising Facts About Wolves’ Diets:
✅ Wolves Have Been Observed Eating Fruits & Vegetables 📌 A study on wild wolves in Voyageurs National Park found that they regularly consume blueberries, apples, and other plant matter in addition to meat. (Read Study)
✅ Wolves Actively Seek Out Plant-Based Foods 📌 Research on Bronze Age and Iron Age dog remains showed that ancient dogs were already consuming plant-rich diets. (Read Study)
📌 If even wolves rely on plant-based nutrition, why should dogs be fed as if they are strict carnivores?
📌 The Myth of “Obligate Carnivore” Diets for Dogs
📌 What is an obligate carnivore? Animals like lions and tigers require at least 70% meat in their diet to survive because they lack the ability to extract nutrients many essential nutrients from plant matter.
📌 What about dogs? ❌ Dogs are not obligate carnivores. ❌They can digest and thrive on plant-based ingredients. ❌ Science has repeatedly confirmed that dogs do not need meat to meet their nutritional needs. (Read Study)
💡 Dogs are not only capable of thriving on a well-formulated plant-based diet, but studies show it may actually be the healthiest and least hazardous feeding approach.
🔬 Why Do Most Carnivore Species Eat Plant Matter?
1️⃣ Nutritional Benefits from Plant Foods
Wild carnivores instinctively consume plants for essential nutrients that may be lacking in meat.
Berries, fruits, and grasses provide antioxidants, fiber, vitamins, and minerals that help maintain overall health.
Studies show that even predominantly carnivorous species benefit from phytochemicals and fiber to support gut health and immunity.
📖 Scientific Evidence: ✔️ Study on Wild Wolves: Up to 83% plant matter was found in wolf diets during certain seasons, including blueberries, grass, and apples. (PubMed) ✔️ Big Cats & Fruits: Leopards and tigers have been documented eating berries and grasses for digestive aid and nutrient supplementation. (Smithsonian Research)
2️⃣ Seasonal Availability & Opportunistic Feeding
Carnivores often adjust their diet based on food availability.
During summer and fall, fruits and berries become more abundant and are readily consumed.
When prey is scarce, carnivores turn to alternative food sources like plants for survival.
📖 Scientific Evidence: ✔️ Arctic Foxes consume berries in late summer and fall due to scarce prey availability. (NCBI Study) ✔️ Coyotes in Urban Areas eat up to 23% plant matter in their diet due to food scarcity and adaptation. (University of California Study)
3️⃣ Digestive Health & Natural Parasite Control
Some carnivores eat grass and fibrous plants to aid digestion, help with hairball removal, or eliminate internal parasites.
Grass-eating behavior has been observed in wild and domestic carnivores to stimulate the digestive tract.
📖 Scientific Evidence: ✔️ Lions & Tigers: Occasionally eat grass to cleanse their digestive system and induce vomiting when needed. Tigers have been shown to consume grass and berries on a regular basis for digestion aid. (NCBI Study) ✔️ Canids (Wolves, Coyotes, Foxes): Frequently consume grasses for fiber to improve digestion and gut motility. (Journal of Mammalogy)
4️⃣ Scavenging & Survival Adaptability
Carnivores are opportunistic feeders, meaning they eat what’s available to survive.
During food shortages, they consume plant-based foods like fruits, roots, and even agricultural crops.
This adaptive behavior ensures survival during harsh environmental conditions.
📖 Scientific Evidence: ✔️ Black Bears (technically omnivores, but with a carnivorous ancestry) eat up to 90% plant-based foods when meat is unavailable. (National Park Service) ✔️ Dholes (Wild Asian Dogs): Though hypercarnivores, they have been observed eating wild figs and berries in times of low prey availability. (IUCN Dhole Conservation Research)
A comprehensive study titled "Plant‐eating carnivores: Multispecies analysis on factors influencing plant consumption in felids" analyzed data from 213 published articles covering 24 felid species.The findings revealed that smaller felid species exhibited higher frequencies of plant consumption compared to larger ones.This behavior is attributed to various factors, including digestive health and nutritional benefits. (Study)
It highlighted that plant consumption is a common behavior among felids, influenced by factors such as body size and environmental conditions.This behavior is thought to aid in digestion and provide essential nutrients not readily available in a strictly carnivorous diet.
🟢 Wolves are NOT obligate carnivores because they can digest plant materials and adapt their diet when necessary. While they thrive on meat, they have been observed consuming fruits, berries, grasses, and other plant-based foods both in the wild and in controlled studies.
📌 What Should You Feed Your Dog?
📌 The healthiest diet for dogs is one that is: ✅ Balanced & complete—provides all essential nutrients. ✅ Fresh & anti-inflammatory—reduces the risk of chronic disease. ✅ Whole-food based—avoids ultra-processed pet foods (kibble, canned food).
💡 A fresh, plant-based diet formulated for dogs meets all of these criteria and has been scientifically proven to support long-term health and longevity.

One of the biggest misconceptions about canine nutrition is that dogs cannot digest plant-based foods. However, scientific research has proven otherwise—dogs have undergone significant genetic adaptations that allow them to efficiently digest and utilize starches and plant-based nutrients.
📌 The Science: How Dogs Evolved to Digest Starch Efficiently
📌 Dogs Have Been Eating Starch-Rich Diets for Over 7,000 Years Scientific evidence shows that domesticated dogs were fed whole grains and plant-based foods as main ingredients in their diet starting as early as the Neolithic period. These dietary changes led to a major genetic adaptation in their ability to digest starch. (Read Study)
📌 Dogs Have Up to 30 Copies of the AMY2B Gene for Starch Digestion One of the most significant genetic adaptations in dogs compared to wolves is the duplication of the AMY2B gene, which codes for amylase, an enzyme that breaks down starch.
✅ Dogs Have: Up to 30 copies of the AMY2B gene. ❌ Wolves Have: Only 2 copies of the gene.
📌 What Does This Mean? 🔎 The more copies of the AMY2B gene an animal has, the better it is at digesting and metabolizing starches. This means that dogs are naturally adapted to thrive on plant-based and carbohydrate-rich diets. (Read Study)
📌 This genetic adaptation is similar to that seen in humans, who also evolved to digest starch more efficiently as they transitioned to agriculture-based diets. (Read Study)
📌 What About Wolves? Aren’t Dogs Just Carnivores?
📌 While dogs evolved to digest starch efficiently, wolves remained primarily meat eaters. 📌 Wolves still only have 2 copies of the AMY2B gene, making them less capable of digesting carbohydrates.
🔎 This is one of the key genetic differences between dogs and wolves, proving that dogs have adapted to a more omnivorous diet over thousands of years of domestication. (Read Study)
📌 Dogs Are Not Wolves—They Have Different Nutritional Needs.
❌ Feeding dogs like wolves ignores their evolutionary adaptations. ✅ Providing dogs with well-balanced, plant-based nutrition supports their natural digestive capabilities and overall health.
📌 Why Does This Matter for Your Dog’s Health?
📌 A diet that includes fresh, whole plant foods supports: ✅ Better digestion—Dogs are fully capable of digesting starches and plant-based nutrients. ✅ Longer lifespan—Studies show plant-based diets support longevity and disease prevention. ✅ Reduced inflammation—Fresh, whole plant foods are anti-inflammatory and support gut health.
📌 The Takeaway? Science confirms that dogs are adapted to digest plant-based foods efficiently. A properly balanced, fresh, plant-based diet is not only safe but highly beneficial for canine health and longevity.
📌 What Should You Feed Your Dog?
📌 The healthiest diet for dogs is one that is: ✅ Nutritionally complete & balanced—meeting all essential nutrient requirements. ✅ Fresh & anti-inflammatory—reducing the risk of chronic disease. ✅ Whole-food based—avoiding ultra-processed pet foods (kibble, canned food).
💡 A well-formulated plant-based diet provides all the necessary nutrients while supporting long-term health.

A common misconception is that a dog’s teeth indicate they must consume a carnivorous, meat-heavy diet. However, when we analyze their dental structure and compare it to other members of the Carnivora order, including omnivores and even herbivores, we see a different picture.
One of the most compelling examples is the giant panda, which, despite having a very similar dental structure to dogs and belonging to the same Carnivora order, is 100% herbivorous.
Understanding a Dog’s Teeth Structure
To properly assess the role of teeth in dietary adaptation, let's break down the key components of a dog's dentition:
1. Incisors (Front Teeth)
📌 Dogs & Pandas: Both species have 12 incisors, which are used for nibbling, grooming, and picking up food rather than tearing through flesh.
2. Canines ("Fangs")
📌 Dogs & Pandas: Both species have 4 prominent canine teeth, which are often mistaken as a defining feature of carnivory. However, these teeth also serve non-carnivorous functions, such as grasping, carrying, and defense.
3. Premolars (Teeth for Crushing & Grinding)
📌 Dogs: 16 premolars 📌 Pandas: 12 premolars
Premolars are essential for breaking down all types of food, not just meat. Both species have similar enamel structures, which still retain traits from their carnivorous ancestors but serve a more omnivorous function today.
Interestingly, herbivores tend to have more premolars (around 16), while carnivores usually have fewer (12–16). The panda is an exception, with 12 premolars despite its herbivorous diet.
4. Molars (Chewing & Grinding)
📌 Dogs: 16 molars 📌 Pandas: 12 molars
Molars are designed to grind and chew food for better digestion. Dogs have even more molars than pandas, suggesting a diet requiring significant mechanical processing—consistent with omnivory rather than obligate carnivory.
In contrast, strict carnivores, like lions and tigers, have only 30–34 teeth, with fewer molars because they swallow large chunks of meat without chewing extensively.
Does Bite Force Define Diet?
Some claim that dogs’ bite force is evidence of a meat-based diet. However, research shows that bite strength varies widely across dietary categories:
📌 The Giant Panda ranks 5th in bite force among Carnivora species, surpassing wolves and some big cats. 📌 Hippos, herbivores, have the strongest bite force of all land animals—far greater than any carnivore. 📌 Dogs’ bite forces range from 13 to 1,394 Newtons, with 77% of dogs showing a force below 400 Newtons.
This evidence indicates that bite force does not determine diet, as strong bite forces are found in carnivores, omnivores, and herbivores alike.
Dogs Have an Omnivorous Dental Structure
When we compare domesticated dogs to omnivorous species like raccoons, foxes, and bears, we find they all have 40–42 teeth, suitable for both plant and animal matter. In contrast, obligate carnivores (lions, tigers, etc.) have fewer teeth (30–34) and lack extensive grinding surfaces.
This evidence, combined with studies on dog genetics, metabolism, and digestive enzymes, demonstrates that dogs are not obligate carnivores but omnivorous scavengers—fully capable of digesting and thriving on a plant-based diet.
1️⃣ Giant Panda Teeth (First Image)
🦷 Giant Panda's Teeth: A Perfect Example of Evolutionary Adaptation Despite having large, sharp canines, the Giant Panda (Ailuropoda melanoleuca) is an herbivore that consumes 99% bamboo. Their teeth resemble those of carnivores, yet their digestive system has evolved to break down fibrous plant material rather than meat. Studies confirm that pandas have digestive enzymes suited for plant-based diets, despite their classification under the order Carnivora.
📌 Evidence: 🔹 Nature Journal (2013): Genetic adaptations in pandas support a plant-based diet. 🔹 Scientific Reports (2021): Panda gut microbiome mirrors that of herbivores, despite having a carnivore-like dentition.
2️⃣ Dog Teeth (Second Image)
🐶 A Dog’s Teeth: Adapted for an Omnivorous Diet Domesticated dogs (Canis lupus familiaris) have 42 teeth, including sharp canines (for gripping) and broad molars(for grinding plant matter). Unlike obligate carnivores, dogs produce amylase—an enzyme for digesting starch—indicating they have evolved for plant consumption as well.
📌 Evidence: 🔹 Nature (2013): Dogs have up to 30 copies of the AMY2B gene, allowing them to efficiently digest starch. 🔹 PubMed (2014): Dogs can extract nutrition from plant-based foods as effectively as from meat.
3️⃣ Dog Skull (Third Image)
💀 The Skull of a Dog: Built for Versatility This dog skull shows mixed dentition, suitable for consuming both meat and plants. Unlike obligate carnivores (which lack molars suited for grinding), dogs have large, flat molars, proving they have adapted to process starches and fibrous plant material over thousands of years.
📌 Evidence: 🔹 Proceedings of the Royal Society (2022): Domesticated dogs adapted to omnivorous diets over 40,000 years ago. 🔹 Journal of Animal Science (2023): Dogs meet all their nutritional needs from plant-based sources.
4️⃣ Giant Panda Skull (Fourth Image)
🐼 Giant Panda Skull: The Carnivore That Eats Plants Although pandas belong to the Carnivora order, their diet is almost exclusively plant-based. This challenges the assumption that sharp canines = meat diet. Pandas have evolved a unique digestive system, including gut bacteria adapted to break down bamboo.
📌 Evidence: 🔹 Science Advances (2019): Panda gut microbiome resembles that of herbivores. 🔹 Cell Metabolism (2021): Genetic evolution in pandas favors plant digestion despite their dentition.
Key Takeaway
🔎 Dental anatomy alone is not proof of dietary needs! Both dogs and giant pandas have sharp teeth, yet one thrives on bamboo while the other has evolved to digest starch and plant matter. This challenges the outdated idea that dogs require a high-meat diet based on their dental structure.

Final Takeaway
📌 Teeth alone do not determine diet. If they did, the giant panda would still be eating meat instead of bamboo. 📌 Dogs share more dental similarities with omnivores than with obligate carnivores. 📌 Their teeth are designed to process a mixed diet, not exclusively meat.
This makes it clear that dogs are adapted to thrive on plant-based diets, just as they have evolved to digest starch and plant-based foods.

The dietary history of domesticated dogs spans thousands of years and has undergone significant transformations, primarily influenced by human civilization, food availability, and cultural practices. Contrary to popular belief, meat has never been a major component of domesticated dogs' diets until very recently in history.
📌 Prehistoric to Early 1900s: Dogs Lived on an Omnivorous Diet
Based on archaeological findings and historical texts, the average meat content in a dog’s diet ranged from 0% to 10%, depending on factors like food availability, economic status, and the dog's role in society.
Hunting dogs were an exception, often receiving slightly higher meat rations to support their physical activity.
However, for most domesticated dogs, meat scraps and bones were the least significant part of their dietcompared to grains, legumes, and vegetables.
🔬 Scientific Evidence on Ancient Dog Diets:
A study on Bronze & Iron Age dog diets in Spain revealed that dogs primarily consumed grains, legumes, and plant-based proteins mixed with occasional animal proteins (UB Research, 2023).
A PNAS study on ancient human and dog bones found that dogs and humans ate similar diets, with little to no emphasis on meat, showing their dietary evolution mirrored each other over time (PNAS, 2009).
📌 The 20th Century: The Rise of Meat-Heavy Diets
Before 1940, dogs were commonly fed stale bread, grains, boiled vegetables, legumes, and table scraps with minimal meat content.
Starting around 1941, commercial pet food companies drastically increased the amount of meat and animal by-products in dog food, reaching 60%–90% of the total diet today.
This abrupt dietary shift contradicts the natural adaptation period required for the canine body, as scientific evidence suggests it takes between 3,000 and 4,000 years for a species to fully adapt to a new diet.
🔬 Scientific Evidence Against Sudden Dietary Shifts:
Evolutionary biology confirms that long-term dietary adaptation requires thousands of years, meaning a drastic increase in meat consumption over just a few decades does not align with natural adaptation (Royal Society, 2016).
A 2021 study in Frontiers in Veterinary Science found that modern dog microbiomes still closely resemble those of plant-eating scavengers, rather than obligate carnivores (PMC, 2021).
📌 Dogs Have Always Been Omnivorous, Not Carnivorous
Since their domestication, dogs have thrived primarily on whole grains, cooked vegetables, legumes, and even dairy in some regions.
Ancient civilizations, such as Egypt and Rome, fed dogs based on what was accessible—not meat-heavy meals, as meat was an expensive commodity reserved for the wealthy.
A comprehensive historical dietary analysis found that even working dogs in ancient societies rarely received meat as their primary food source (Columella, 1st Century AD).
🔬 Historical Evidence Supporting a Low-Meat Diet in Dogs:
Ancient Roman texts describe dog diets consisting mostly of barley, wheat, vegetables, and legumes (Latin Library).
Medieval literature documents dog feeding habits, where dogs received leftover grains and vegetables with minimal meat consumption (Medieval Cuisine, Wikipedia).
Ancient Egyptian records show that meat was primarily reserved for humans, while dogs were fed grains, vegetables, and dairy (Ancient Egyptian Diet, Wikipedia).
📌 Genetic Adaptation: Dogs Evolved to Digest Starch
Over 7,000 years ago, dogs experienced a significant increase in starch digestion genes, as a result of consuming grains and plant-based foods for an extended period.
Today, dogs have up to 30 copies of the Amy2B gene (the gene responsible for starch digestion), while wolves have only two—proving a genetic adaptation to a plant-based diet.
🔬 Genetic Studies on Canine Starch Digestion:
A groundbreaking study in Nature (2013) showed that domesticated dogs possess genetic mutations allowing them to digest starch-rich diets, unlike wolves (Nature, 2013).
A study on starch digestion genes (PNAS, 2017) found that dogs and humans evolved in parallel, adapting to carbohydrate-rich diets as early as 10,000 years ago (PNAS, 2017).
📌 What This Means for Modern Dogs
The idea that dogs require a high-meat diet is a modern marketing construct, not a biological necessity.
A diet rich in whole plant foods aligns better with their long history and genetic adaptations than today’s ultra-processed, meat-heavy diets.
With proper formulation, dogs can thrive on a plant-based diet, just as they have for thousands of years.

Are Dogs and Humans More Similar Than We Think? The Science Behind Our Genetic Connection
The bond between humans and dogs goes far beyond companionship—it’s written in our DNA. Did you know that dogs and humans share up to 95% of their genetic makeup? Due to thousands of years of co-evolution, our four-legged companions have developed striking genetic, physiological, and even disease-related similarities to us. But what does this mean for their health, nutrition, and longevity?
📌 How Genetically Similar Are Humans and Dogs?
📌 The Numbers Behind Our Genetic Connection
The human genome contains around 19,900 genes, while dogs have approximately 19,000 genes.
Scientists estimate that over 17,000 of these genes are identical between dogs and humans, affecting biological functions, immune responses, and disease susceptibility.
Dr. Rodney Page, professor of medical oncology, highlights this close genetic link: 🗣 "The genetic difference between humans and dogs is quite small. Humans and dogs are 95 percent identical genetically—and the diseases that affect humans, including breast cancer, prostate cancer, and melanoma, are almost identical." (NBC News)
📌 What Does This Mean for Health & Disease?
Because of these genetic similarities, dogs naturally develop many of the same chronic diseases as humans (over 300 diseases in common), making them crucial in medical research and highly responsive to dietary and lifestyle changes.
📌 Shared Health Conditions Between Dogs & Humans
🐶 Cancer Research 🔬 Dogs are used as models for human cancer research because they develop spontaneous tumors that mimic human cancers closely in behavior, response to treatment, and progression. (Read Study)
💓 Heart Disease 🔎 Studies show that the structure and function of the canine heart are nearly identical to humans, making them prone to similar cardiac conditions. Both dogs and humans benefit from heart-healthy diets rich in anti-inflammatory foods. (Harvard Study)
🦠 The Gut Microbiome 💡 Harvard research shows that dogs' gut microbiomes closely are almost 100% identical of those of humans, particularly those following Western diets. This means that processed foods harm dogs in the same way they harm humans—leading to inflammation, digestive disorders, and chronic disease. (Read Study)
🌿 Allergies & Immune Disorders 📌 Dogs develop autoimmune conditions, atopic dermatitis, and chronic inflammatory diseases, just like humans—many of which are exacerbated by poor diet and ultra-processed pet food. (Read Study)
📌 The Evolutionary Perspective: Why Are Dogs So Similar to Humans?
🕰 Dogs have been evolving alongside humans for over 40,000 years—and their genetics, metabolism, and nutritional needs have shifted to reflect human diets.
📌 The AMY2B Gene & Starch Digestion
Wolves have only 2 copies of the AMY2B gene, which helps break down starch.
Dogs have evolved to have up to 30 copies—allowing them to thrive on plant-based foods. (Read Study)
📌 What This Means for Your Dog ✅ Dogs are not biologically required to eat meat—they can thrive on a well-formulated, fresh, plant-based diet that supports their genetic adaptations and reduces the risk of chronic disease.

The Science Behind Plant-Based Protein for Dogs
Many dog parents worry that a plant-based diet might not provide enough protein for their canine companions. However, scientific research shows that dogs can not only meet but exceed their protein needs through plant-based sources. In fact, plant proteins are often the preferred type of dietary protein for dogs, offering numerous health benefits compared to animal proteins, while being naturally anti-inflammatory.
📌 Are Plant Proteins Sufficient for Dogs?
✅ Yes! Dogs can obtain all essential proteins from plant-based sources. Proteins are made up of amino acids, which are the true building blocks of a dog’s body. These essential amino acids are found in both animal and plant-based ingredients, and dogs can synthesize protein just as effectively from plant sources.
📌 Dogs have evolved to digest plant proteins efficiently, with studies showing no significant difference in protein absorption when meat proteins are replaced with plant proteins. A study published in the journal Frontiers in Animal Science evaluated the apparent total tract digestibility (ATTD) of canine diets differing in protein sources. The findings indicated that plant-based (vegan) and animal-based diets with similar nutrient profiles had comparable nutrient digestibility, suggesting that dogs can efficiently utilize plant proteins.
📌Plant-based protein consumption is associated with lower risks of chronic diseases, including cancer and heart disease. Research indicates that plant-based diets are linked to a reduced risk of chronic diseases. For instance, the Dietary Guidelines for Americans highlight that plant-based protein sources, such as beans, peas, and lentils, provide essential nutrients and are associated with health benefits, including lower risks of heart disease and certain cancers.
📌According to the USDA, tempeh contains more protein per cup than salmon, making it an exceptionally high-quality plant-based protein source for dogs. USDA data reveals that one cup (166 grams) of tempeh contains approximately 34 grams of protein, whereas a comparable serving size of salmon provides about 31 grams of protein. This makes tempeh a highly potent plant-based protein source.
These insights underscore that dogs can effectively digest plant proteins, and incorporating high-quality plant-based protein sources like tempeh can contribute to their overall health and well-being.
📌 Why Are Plant Proteins Healthier Than Animal Proteins?
📌 Plant-Based Proteins Reduce Disease Risk Just as in human nutrition, consuming more plant-based proteins and fewer animal proteins has been linked to: ✅ Lower risks of cancer (Read Study) ✅ Reduced inflammation & better heart health (Read Study). ✅ Healthier weight and longevity (Read Study)
📌 Plant Proteins Are Easier to Digest & Absorb While plant proteins have slightly lower bioavailability than animal proteins, there are simple ways to improve their absorption, such as: 🌱 Soaking & sprouting plant-based proteins to make them more digestible. 🌾 Using complete plant protein sources like quinoa, which contains all essential amino acids dogs need. (Read Study)
📌 Fermented Proteins Increase Nutrient Absorption Tempeh, a fermented soybean product, enhances protein digestibility due to its fermentation process, making it a superior plant-based protein source for dogs.
📌 Dogs Create Their Own Proteins Many people assume dogs must eat meat for protein, but in reality: 🔎 Proteins are not "eaten"—they are built from amino acids in a dog's body. 🌱 Essential amino acids are equally available from plant-based foods.
📌 What This Means for Your Dog
✅ Dogs do not need meat to meet their protein needs—as long as their diet includes a variety of complete and complementary plant proteins. ✅ A fresh, plant-based diet provides all the essential nutrients dogs need while avoiding the health risks of animal proteins and ultra-processed pet food.
📌 As a Canine Nutritionist, I specialize in formulating fresh, plant-based meal plans tailored to support your dog’s optimal protein intake, gut health, and longevity.

Debunking the Taurine Deficiency Myth
A common misconception is that dogs must eat meat to get taurine, and without it, they risk taurine deficiency and life-threatening heart disease, such as dilated cardiomyopathy (DCM).
📌 But is this true? No! Science confirms that dogs naturally produce taurine on their own and do not require meat to obtain it.
📌 What Is Taurine & Do Dogs Need It in Their Diet?
✅ Taurine is a non-essential amino acid for dogs, meaning they can synthesize it within their own bodies—unlike cats, who require it from food. ✅ Dogs produce taurine from methionine and cysteine, two amino acids that are widely available in plant-based foods and vegan supplements. ✅ Taurine deficiencies in dogs are rare and typically due to genetic factors, malabsorption, or pre-existing health conditions.
📌 If a dog is unable to synthesize taurine properly, a vegan taurine supplement can be used—but this is not necessary for the vast majority of dogs.
📌 The Truth About Taurine & Dilated Cardiomyopathy (DCM)
Many dog parents worry that a plant-based diet may cause DCM (Dilated Cardiomyopathy)—a heart condition linked to low taurine levels. However, after years of investigation, the FDA (Food and Drug Administration) found no direct link between grain-free or legume-rich diets and DCM.
🔎 What Did Scientists Discover? "We wanted to gain the best understanding of this issue, so we examined the results of more than 150 studies, which taken together, did not support a link between grain-free and legume-rich diets and DCM," said Sydney McCauley, PhD, an animal nutritionist and lead author of the study. (Read More)
📌 Key Takeaways on DCM & Taurine: ✅ There is no proven connection between plant-based diets and DCM. ✅ Taurine deficiency is not caused by a plant-based diet but rather by genetics, medical conditions, or ultra-processed pet foods with poor bioavailability. ✅ A fresh, balanced, plant-based diet provides all necessary amino acids for dogs to synthesize taurine naturally.
📌 Where Do Dogs Get Taurine & L-Carnitine From in a Plant-Based Diet?
📌 Dogs also need L-carnitine, another amino acid linked to heart health. 🔎 L-carnitine is naturally synthesized from methionine and lysine, both of which are abundant in plant-based foods. 📌 Excellent Plant-Based Sources of Taurine, Methionine & Lysine for Dogs: 🌱 Lentils, chickpeas, and black beans (rich in lysine & methionine) (Read Study) 🌱 Tempeh (fermented soybeans)—contains higher protein than salmon and boosts amino acid absorption (Read USDA Data) 🌱 Quinoa, hemp seeds, pumpkin seeds, and oats—all provide essential amino acids for heart and muscle health (Read Study)
📌 Conclusion: Your dog does NOT need meat to meet their taurine needs! A well-balanced, plant-based diet provides all the essential amino acids for taurine synthesis, supporting heart health, longevity, and overall well-being.
📌 What This Means for Your Dog
✅ Dogs naturally produce taurine from plant-based amino acids. ✅ There is no scientific evidence that plant-based diets cause taurine deficiency. ✅ DCM is not caused by a properly balanced, plant-based diet. ✅ A fresh, plant-based diet can provide optimal nutrition for long-term heart health.
📌 As a Canine Nutritionist, I specialize in formulating fresh, plant-based meal plans that ensure your dog gets the essential amino acids they need for heart health, longevity, and disease prevention.

The Shocking Truth About Commercial Pet Food
Many dog parents trust that commercial pet food—especially veterinary diets—provide all the essential nutrients their dogs need. However, scientific research has found alarming gaps in nutrient levels, raising serious concerns about the long-term impact on canine health.
📌 Are Commercial Dog Foods Really Nutritionally Complete?
A study published in Scientific Reports analyzed 177 commercial pet foods (97 wet and 80 dry) sold in the UK, testing them against established nutritional standards.
🔎 The Findings:
❌ Only 6% of wet foods (6/97) were nutritionally complete. ❌ Only 38% of dry foods met minimum nutrient requirements. ❌ 20% of wet foods failed to meet the minimum nutritional standards for canine health. ❌ 76% of wet foods exceeded the maximum safe levels of nutrients—posing health risks for dogs and cats. ❌ Significant nutrient variations between batches, raising concerns about consistency.
📌 What This Means: "If fed exclusively and over an extended period, a number of these pet foods could impact the general health of companion animals." (Read Study)
📌 The Risks of Nutritional Imbalances in Pet Food
Many kibble and canned diets fail to provide adequate nutrition, while others contain excessive, even harmful, nutrient levels. Both can contribute to long-term health problems in dogs.
🔴 Nutrient Deficiencies in Pet Food:
❌ Vitamin D Deficiency – Studies show that many commercial pet foods contain insufficient vitamin D, which can lead to bone disorders, immune dysfunction, and increased cancer risk. (Read Study) ❌ Low B Vitamins (B12, B6, Folate) – Critical for nerve function, digestion, and energy metabolism. Deficiencies can cause anemia, cognitive decline, and digestive disorders. (Read Study) ❌ Amino Acid Imbalances – Low methionine, cysteine, and taurine levels have been linked to dilated cardiomyopathy (DCM) and poor skin health. (Read Study) ❌ Low Omega-3 Fatty Acids – Most kibble is rich in inflammatory omega-6 fats but lacks anti-inflammatory omega-3s, which are essential for heart, brain, and skin health. (Read Study)
🟡 Excess Nutrients Can Be Harmful Too!
❌ Over-supplementation of Calcium & Phosphorus – Found in many commercial pet foods, excessive amounts can cause kidney disease and urinary issues, especially in senior dogs. (Read Study) ❌ Excess Vitamin A – Found in some pet foods, high levels can lead to toxicity, causing bone deformities and liver damage. (Read Study) ❌ Synthetic Additives & Preservatives – Many pet foods contain synthetic antioxidants (BHA, BHT, ethoxyquin), which have been linked to organ damage, cancer, and hormone disruption. (Read Study)
📌 Why Do So Many Commercial Diets Fail to Meet Nutritional Standards?
🔎 1️⃣ Ultra-Processing Depletes Nutrients Most kibble and canned pet food undergo extreme heat processing, destroying delicate vitamins, amino acids, and antioxidants. To compensate, synthetic supplements are added—but these have poor bioavailability compared to whole-food sources. (Read Study)
🔎 2️⃣ Low-Quality Ingredients & Fillers Many kibble and canned foods contain: ❌ Rendered animal by-products (low-grade meats, bones, and waste tissues). ❌ High-carb fillers (corn, wheat, soy) that provide little nutritional value but increase inflammation. ❌ Chemical preservatives & artificial flavors to extend shelf life, despite evidence linking them to chronic disease. (Read Study)
🔎 3️⃣ Loose Regulatory Standards Pet food regulations allow for significant nutrient variations, meaning brands can claim "complete and balanced" status even if their food fails to meet essential nutrient guidelines. (Read Study)
📌 The Bioavailability Problem: Why Ultra-Processed Pet Foods Fail Dogs
Even if a pet food contains adequate nutrient levels on paper, the bioavailability (how well those nutrients are absorbed and utilized) is often poor in ultra-processed foods. 🔎 Studies show: ✅ Fresh diets result in significantly better nutrient absorption than kibble or canned food. (Read Study) ✅ Many synthetic vitamins and minerals in commercial pet food are poorly absorbed. (Read Study) ✅ Heat processing reduces the bioavailability of amino acids and essential fatty acids. (Read Study)
📌 What’s the Alternative? Fresh, Anti-Inflammatory Nutrition for Dogs
Instead of relying on ultra-processed, nutritionally inconsistent kibble and canned foods, a fresh, whole-food diet provides superior nutrition with better bioavailability. ✅ Whole, fresh, plant-based foods naturally provide essential nutrients compared to synthetic additives in pet food. ✅ A properly formulated fresh diet ensures dogs receive balanced nutrition without harmful fillers or preservatives. ✅ Research shows that dogs thrive on diets rich in plant proteins, whole grains, vegetables, and essential fatty acids—supporting longevity, gut health, and disease prevention.

The Truth About Synthetic Nutrients in Pet Food
Many dog parents trust that commercial pet food contains all the essential nutrients their dogs need. However, scientific research shows that synthetic nutrients—commonly used in pet foods—are poorly absorbed and can contribute to long-term nutritional deficiencies, organ damage, and even toxicity.
📌 Why Are Synthetic Nutrients a Concern? Most kibble and canned pet foods rely on synthetic vitamins and minerals to compensate for nutrient losses during ultra-processing. However, these lab-made nutrients differ significantly from naturally occurring vitamins found in whole foods.
🔎 Key Problems with Synthetic Nutrients: 1️⃣ Poor Bioavailability: The canine body struggles to recognize and absorb synthetic nutrients properly. 2️⃣ Lack of Co-Factors: Natural vitamins come with co-factors (enzymes, minerals, and antioxidants) that aid absorption. Synthetic nutrients lack these, making them far less effective and having a poor bioavailability. 3️⃣ Potential for Toxicity: Unlike water-soluble vitamins that are excreted in urine, fat-soluble synthetic vitamins (like Vitamin D and A) accumulate in the body, leading to toxic effects over time. 4️⃣ Hidden Nutrient Deficiencies: Blood tests may show nutrients in the bloodstream, but this does not mean they are properly absorbed or utilized by the body. This can create a false sense of nutritional adequacy while deficiencies silently develop.
🛑 The Hidden Dangers of Vitamin D in Pet Food
📌 Synthetic Vitamin D Toxicity: A Major Issue in Commercial Pet Food
🔎 Studies have found that most pet foods—both kibble and canned—contain excessive amounts of synthetic Vitamin D, leading to a high risk of toxicity.
❌ Vitamin D is fat-soluble, meaning it accumulates in tissues and organs over time. Unlike water-soluble vitamins, excess Vitamin D cannot be easily eliminated, leading to poisoning. ❌ High levels of synthetic Vitamin D cause:
Kidney damage and failure
Heart problems
Vomiting, lethargy, and weight loss
Death in severe cases
🔎 Pet Food Recalls Due to Vitamin D Toxicity:
2018 Recall: The FDA recalled multiple dog food brands due to dangerously high Vitamin D levels. (Read FDA Report)
2023 Recall: Purina recalled dry dog food due to toxic Vitamin D levels. (Read Study)
🟡 What This Means: Many pet foods contain synthetic Vitamin D levels far above safe limits, increasing the risk of toxicity over time.
🔎 Canine Nutritional Deficiencies from Synthetic Nutrients
Even when synthetic vitamins and minerals meet “minimum nutritional requirements” on paper, they may not be properly utilized by the body. This can lead to long-term nutrient deficiencies, which increase the risk of chronic diseases.
📌 Common Nutritional Deficiencies in Dogs Fed Commercial Pet Food: 1️⃣ Vitamin B Deficiency (B12, B6, Folate) – Essential for nerve function, digestion, and red blood cell production. Deficiencies can cause anemia, cognitive decline, and poor gut health. (Read Study) 2️⃣ Magnesium Deficiency – Increases risk of heart disease, muscle weakness, and nervous system disorders. (Read Study) 3️⃣ Zinc Deficiency – Linked to skin conditions, immune dysfunction, and poor coat health. (Read Study) 4️⃣ Taurine & Carnitine Deficiencies – Contribute to heart disease, particularly dilated cardiomyopathy (DCM). (Read Study)
📌 Why Are These Deficiencies So Dangerous? Nutrient deficiencies play a major role in many chronic diseases, including: ✅ Cancer – Linked to deficiencies in Vitamin D, B vitamins, and antioxidants. (Read Study) ✅ Heart Disease – Deficiencies in taurine, carnitine, magnesium, and omega-3s are major contributors. (Read Study) ✅ Arthritis & Joint Disease – Caused by low levels of key anti-inflammatory nutrients, including Vitamin C, Omega-3s, and glucosamine. (Read Study)
🔎 Blood Tests Don’t Always Reveal Deficiencies! 📌 Many veterinarians assume that if a dog’s bloodwork shows normal nutrient levels, they are getting enough nutrition. But synthetic nutrients may circulate in the blood without being properly absorbed or utilized. 📌 This means that deficiencies can go undetected for years—only appearing when disease has already developed.
📌 What’s the Solution? Fresh, Bioavailable Nutrition
Instead of relying on poorly absorbed synthetic nutrients in pet food, dogs benefit most from whole-food, bioavailable nutrition that provides vitamins, minerals, and co-factors in their natural form.
✅ Fresh, anti-inflammatory, plant-based foods naturally provide essential nutrients with high bioavailability. ✅ Whole foods come with co-factors, ensuring better absorption and utilization compared to synthetic additives. ✅ A properly formulated fresh diet ensures dogs receive the right balance of nutrients—without harmful fillers or synthetic chemicals.
📌 As a Canine Nutritionist, I specialize in creating science-backed, fresh meal plans tailored to your dog's needs—ensuring they get the right nutrients, in the right form, without the risks of synthetic additives.

Yes! Whether your dog eats meat-based, fish-based, or plant-based commercial pet food—kibble or canned—the vast majority of their nutrients already come from vegan sources. 🥦🐶
🔬 The Science Behind It
Most pet foods rely on synthetic nutrients rather than real, whole foods. These nutrients are lab-made and vegan by definition—not sourced from meat, but from synthetic chemical compounds.
💡 How is Commercial Pet Food Made?
To understand this, let’s break down the process:
1️⃣ The Food Extrusion Process 🔥
Ingredients are mixed and heated to extreme temperatures (typically 250°C) for an extended period.
This intense heat destroys most naturally occurring vitamins, minerals, and amino acids.
The final result? A brown paste with almost zero natural nutrients.
2️⃣ Nutrient Loss & Synthetic Replacement ⚗️
Because extreme processing eliminates almost all nutrients, pet food manufacturers re-add synthetic vitamins, minerals, and amino acids to meet regulations.
These lab-made nutrients are derived from chemical processes, petroleum derivatives, and synthetic compounds—making them vegan.
3️⃣ Kibble Formation 🍪
The synthetic nutrient-infused paste is shaped into kibble using perforated plates ("dies").
The final product is sprayed with fats and artificial flavors to make it palatable.
❓ Why 99% and not 100%?
A tiny fraction of pet food brands include:
Animal-derived vitamin D (though most use synthetic vitamin D).
Fish-based Omega-3 (instead of plant-based sources like algae).
🚨 But make no mistake! Even if you feed your dog a meat-based kibble, they’re already getting almost all their nutrients from vegan sources.
⚠️ The Problem with Ultra-Processed Pet Food
🔎 Did you know? All kibble and canned pet food are classified as ultra-processed foods (UPFs)—the lowest nutritional category of food.
📉 Research shows that UPFs: ❌ Destroy natural food structures due to industrial processing. ❌ Are linked to chronic diseases and reduced lifespan in both humans and animals. ❌ Contribute to inflammation, digestive issues, and weakened immunity in dogs.
📖 Scientific Evidence: 📌 Increased UPF intake is correlated with higher disease risks (PMC8538030). 📌 Synthetic vitamins in pet food have poor bioavailability, meaning dogs absorb fewer nutrients (Dr. Judy Morgan). 📌 A fresh, whole-food diet can significantly improve gut health and longevity (Harvard).
🌱 Whole Foods vs. Ultra-Processed Foods
According to Medical News Today: 🗣️ “Fruits, vegetables, and grains contain health-promoting plant compounds with antioxidant, anti-inflammatory, and anti-carcinogenic properties. These include flavonoids, anthocyanins, tannins, and carotenoids. The best way to obtain essential nutrients is through whole, unprocessed, or minimally processed foods.” (Source)
🔬 Scientific research has confirmed it: A fresh, whole-food diet beats ultra-processed pet food every time when it comes to: ✅ Reducing inflammation 🔥 ✅ Supporting gut health 🦠 ✅ Preventing chronic disease 🏥 ✅ Improving longevity ⏳
1️⃣ Industry Reports & Expert Statements
🔍 Key Fact: Almost all pet food relies on synthetic vitamins, minerals, and amino acids—which are lab-made and not derived from animal sources.
Evidence & Reports to Use:
✔️ The Global Alliance of Pet Food Associations (GAPFA) confirms that most pet food nutrients are synthetic: 📌 GAPFA Report: How Pet Food is Made

✔️ Big Dog Pet Foods Report: 🔬 Explains how heating and extrusion destroy essential vitamins like Vitamin A, B-complex, C, and E, making it necessary to add synthetic versions. 📌 Big Dog Pet Foods: The Impact of Processing
3️⃣ Ingredient Breakdown: Where Do Nutrients in Pet Food Come From?
To prove that pet food is 99% nutritionally vegan, we need to break down key nutrients and their sources:
📌 𝗖𝗼𝗺𝗺𝗼𝗻 𝗦𝘆𝗻𝘁𝗵𝗲𝘁𝗶𝗰 𝗡𝘂𝘁𝗿𝗶𝗲𝗻𝘁𝘀 𝗶𝗻 𝗣𝗲𝘁 𝗙𝗼𝗼𝗱 (Vegan Sources):
Vitamin A (Retinol Acetate / Palmitate) – Made from petroleum derivatives 🛢️
Vitamin D2 (Ergocalciferol) & D3 (Cholecalciferol) – Mostly synthetic, sometimes from animal sources 🟡
Vitamin E (dl-α-Tocopherol Acetate) – Produced from vegetable oils 🌿
Vitamin K (Menadione Sodium Bisulfite Complex) – Completely synthetic ⚗️
B Vitamins (B1, B2, B3, B6, B12, Biotin, Folic Acid, Pantothenic Acid) – Made from chemical fermentation 🏭
Vitamin C (Ascorbic Acid) – Made synthetically from glucose 🍊
Calcium & Phosphorus – From mineral deposits ⛰️
Zinc, Iron, Copper, Manganese, Selenium – Derived from inorganic minerals 🪨
Taurine – Lab-made through bacterial fermentation 🦠
Amino Acids (Lysine, Methionine, Threonine, Tryptophan, etc.) – Fermented from plant-based sugars 🌽
📌 𝗥𝗲𝗮𝗹𝗶𝘁𝘆 𝗖𝗵𝗲𝗰𝗸: ➡️ 99% of these nutrients are not from animals—they are either synthetic or derived from plant sources. ➡️ The only exceptions are vitamin D3 (sometimes from lanolin) and Omega-3s (sometimes from fish).
📌 𝗙𝗔𝗖𝗧: Even meat-based kibble gets its nutrients from vegan sources because real meat does not survive extreme processing temperatures.
4️⃣ Expert Quotes
💬 Dr. Richard Patton (Animal Nutritionist, PhD): "The pet food industry is entirely dependent on synthetic nutrients. Without them, kibble would be nutritionally deficient."
💬 Dr. Karen Becker (Holistic Vet, Pet Nutritionist): "Pet food companies know that extreme heat destroys natural nutrition. That’s why they add synthetic vitamins and minerals—it’s the only way to meet AAFCO requirements."
