I’m starting with a puppy video today. It shows some of my puppies eating their first meal at 4 weeks … and they’re eating raw food.
You might think it’s not a good idea to feed puppies a raw diet until they’re older. But before you make that choice … you need to understand something called epigenetics.
Some people call this nature vs nurture. It’s all about the importance of your dog’s genes (nature) … and how his food and environment (nurture) can affect his gene expression.
But epigenetics isn’t just about puppies. Your adult dog can also reap HUGE benefits from this cool science.
How Genes Influence Your Dog
Your dog has over 20,000 genes, each made up of DNA. DNA is long strings of proteins called bases – about 3 billion of them. The order of these bases is your dog’s genetic code.
DNA determines your dog’s size, shape and appearance … even his behavior.
Genetically, your dog is very close to the wolf. He shares 98.8% of his genes with the wolf. That might not surprise you. But it’s also the same amount of DNA we share with chimpanzees. So our base physiology is very similar.
Collectively, DNA sequences are called the genome. The genome for all dogs (and wolves) is pretty much the same. DNA sequences also combine with proteins to form your dog’s chromosomes.
When puppies are conceived, one egg and one sperm cell from his parents form a single cell. But the DNA from each parent’s chromosomes is recombined. This genetic shuffling makes every puppy unique. But most physical traits (like size and appearance) are pretty much set.
This is why all dogs have the same number of legs, a furry coat and tail … and why they like to chase and hunt. It’s in their genes.
But what about identical twins? They share the exact same genes and DNA sequence, so they look exactly the same. Yet identical twins have different behaviors, preferences … and diseases.
Studies on identical twins show that only half of their traits are determined by their genes. The other half are determined by their environment. Again, this is nature vs nurture. And their effects are pretty evenly balanced.
The non-genetic factors that shape half of your dog are called epigenetics.
How Epigenetics Affect Cells
In Latin, the word epigenetics means “on top of genetics.” What’s on top of the genes doesn’t change the DNA sequence … but it does change the gene expression (how your dog’s body reads a DNA sequence).
Here’s a simple way to think of it …
Your dog’s cells are constantly dividing. Inside every cell is your dog’s DNA. DNA is the genetic material that gives his cells instructions on how to make other cells and proteins.
But not every cell needs every protein. Almost every cell in the body contains the same DNA sequence. But different cell types will use it in different ways.
A liver cell has a different job than a brain cell. So they get different instructions. In brain cells, the genes that make proteins for liver cells are turned off. And in liver cells, the genes that make proteins for brain cells are turned off.
Skin cells are another example. Most cells don’t need collagen. But skin cells do. So other cells have the gene that makes collagen turned off … while it’s turned on in skin cells.
Epigenetics influences a cell’s specialization through gene expression or silencing. And epigenetics is what makes us unique. It’s why puppies in the same litter grow to be different sizes and have different personalities. The different combinations of genes that are turned on or off make each puppy a different individual.
We humans (and our close genetic cousins the apes) can make our own vitamin D. When our skin is exposed to sunlight, UV rays help us make vitamin D3.
Dogs’ bodies don’t do this. The vitamin D-making gene has been turned off. On the other hand, dogs and wolves can manufacture vitamin C … but in humans and apes, this gene is turned off.
It makes sense. Primal humans naturally eat a diet that’s rich in vitamin C, while the primal dog doesn’t. Human bodies don’t need to make vitamin C so that gene is turned off.
And the primal dog eats a lot of animals that make their own vitamin D. So again, that gene is silenced. Dogs do have the blueprint to convert UV rays to vitamin D … but that gene has been turned off.
This ability to turn genes on and off means our environment can change our gene expression. And that’s true for your dog too.
Now what has that to do with his health?

What Agouti Mice Tell Us
Methylation is the process epigenetics use to regulate gene expression. Methylation turns genes off, while demethylation turns them on. This story illustrates how it works.
Scientists first studied epigenetic changes in an inbred little mouse called the agouti mouse. These mice have a piece of repetitive DNA near their agouti gene. (Agouti is a type of fur coloration).
Normally, agouti mice are brown, normal-looking mice. But if their agouti gene is activated, the mice have a yellow coat. They’re also much more prone to develop obesity, diabetes and cancer.
Here’s the really interesting part …
When agouti mouse mothers get a diet rich in folic acid, their babies’ agouti gene is silenced. This is because folic acid is rich in a substance called methyl. When methyl is added to the agouti mouse’s DNA … the DNA becomes methylated or inactivated.
This is why a mother’s diet and toxin exposure is so important to her baby’s health. It can methylate or unmethylate DNA. This turns some genes on and other genes off.
And it’s not only about what mothers eat. Our ancestors also leave their mark on our genes. Things like how our grandparents or great grandparents ate, affect us now.
One example is the impact of famine on future populations. Several studies show that malnutrition causes higher incidence of diabetes, obesity, heart disease and cancer in later generations. These problems showed up as long as 3 generations later after starvation conditions in China, Netherlands and Norway.
But the good news is .. we can control these effects through epigenetics.
RELATED: Epigenetics aren’t the only way you can prevent cancer in dogs …
Your Dog’s Genes Are Not His Destiny
Epigenetics is great news for your dog. That’s because it means it’s not just his genes that impact his health. It’s also his environment.
Think of it like a movie script. The script is your puppy’s genes. His diet and environment are the director and actors. But with a different director and different actors the movie can turn out completely different. That’s epigenetics at work.
Your puppy is most susceptible to epigenetic changes when he’s still developing … either in the womb or while his cells are still quickly dividing.
So, getting back to my little 4-week-old puppies … now you can see why it’s important to start puppies (and their mom) on a high-quality diet as early as you can.
Even though many vets advise waiting to feed a fresh food diet until your puppy is older … that reduces the quality of the puppy’s diet when he needs it most. So don’t listen to your vet if she tells you to wait! Get your puppy onto fresh food as soon as you can!
RELATED: How to start your puppy on a raw diet …
When I mention the importance of your puppy’s environment … it’s not only about his diet. Epigenetic effects are everywhere. It can be where your dog lives, or how he exercises. Or the chemicals he’s exposed to. Vaccinations, de-wormers, medications, pesticides, heavy metals and other toxins can all change your puppy’s epigenome and contribute to unwanted epigenetic changes.
But what about adult dogs … is epigenetics still important? Well, it’s so important, it has its own word …
Nutrigenomics Is Epigenetics For Adult Dogs
One of the key causes of impaired methylation is poor nutrition. Poor nutrition is simply a diet that’s lacking key bioactive food components that help prevent unwanted methylation.
Nutrigenomics is the science of using these bioactive food components to manipulate health and disease. If we can control methylation, we can control …
- Organ disease
So it’s important that dogs get a good serving of bioactive food components. These foods don’t just prevent disease … they can also treat it.
There are a few powerful bioactive food components you should focus on. That’s because they can change DNA methylation …
Polyphenols are the bioactive parts of fruits, berries and veggies. They can significantly change the epigenome of cancer cells. And they can reactivate silenced genes that allow cancer to grow.
Some important polyphenols include:
- Epigallocatechin-3-gallate (EGCG) from berries, plums, peaches kiwi and avocado
- Resveratrol from cranberries and blueberries
- Curcumin from turmeric
- Isoflavones from alfalfa, lentils and beans
- Isothiocyanates in cruciferous veggies that can inhibit cancer cell growth and modulate methylation
This antioxidant is a trace mineral that can restore the expression of silenced cancer genes. Selenium is found in most meats. Selenium deficiency can lower immune function and stress tolerance.
3. Other Vitamins And Minerals
Most vitamins and minerals play a key role in your dog’s epigenetics. If his diet lacks micronutrients, it can change the way his genes are expressed … and that can silence key functions.
So there’s a lot you can do to change your dog’s disease destiny.
Start by feeding a nutritionally complete diet that supplies folic acid and other important vitamins and minerals. Then include a daily serving of cruciferous veggies, berries and fruits.
You can also get more specific to address specific health issues in your dog. Veterinary homeopath Dr Dee Blanco offers these helpful tips on how different colors of fruits and veggies can help your dog.
- White = strengthen the immune system
- Yellow = improve skin elasticity
- Orange = prevent inflammation
- Red = support heart and blood health
- Purple = protect the nervous system
- Green = detoxify
Keep these colors and your dog’s needs in mind as you shop for his produce. For example, during the spring consider extra green veggies for a detox. Feed orange foods to manage inflammation if he’s got some arthritis. Or feed a rainbow of colors for all-around support.
And remember … avoid all chemicals and toxins that can change your dog’s epigenome. And don’t forget the importance of exercise.
How Exercise Helps
Exercise silences genes that are involved in inflammation. This could explain why regular exercise lowers the risk of cancer and other chronic diseases. But it ties into epigenetics in other ways too.
Exercise increases the expression of genes that suppress tumors. And it lowers the expression of oncogenes. These are abnormal genes that predispose cells to develop cancer. Cancer cells have abnormal DNA methylation. And exercise can reduce and even reverse methylation.
You always knew that a healthy diet and clean living was better for your dog … and now you know the science behind it. So give your dog a fresh, whole food diet. Avoid chemicals and toxins. And keep him moving. You’ll find you can influence your dog’s health more than you thought!

Ahiflower Oil: Why Your Dog Needs It
One of the most important supplements your dog needs is omega fatty acids. Without them, your dog’s immune system, hormones, and inflammatory responses will not function properly. And that increases his risk of illness.
The good news is that omega fats can easily be added to your dog’s diet. And one of the best sources is a tiny flower that you’ve probably never heard of …
What is Ahiflower?
Ahiflower is also known as Buglossoides arvensis. It grows on Prince Edward Island in Canada, but historically it originated in the UK. In fact, Ahiflower has a rich history in the English countryside since it was first recorded in 1597. Its common names also include stone seeds and corn gromwell.
Each Ahiflower flower produces up to four seeds, which are then collected and pressed to create Ahiflower Oil. Ahiflower Oil is a sustainable omega-rich oil and the best comprehensive omega blend on the market. This means that ahiflower oil is an incredibly healthy resource for your dog.
Why you should give Ahiflower Oil to your dog
After protein, fats are the second most important part of your dog’s diet. Omega fatty acids are essential to a dog’s health. The right fats can make your dog healthier and happier, reduce inflammation, and create a soft, silky coat. They also provide energy, control hormones, and aid in cell growth. Fats are even involved in the immune system, which makes them essential for a healthy dog. Studies have even shown that omega-3 fatty acids can protect your dog from cancer.
Dogs need both omega-3 and omega-6 fatty acids. And ahiflower oil is the best all-round blend of the two. It is a rich resource for the omega-3 and omega-6 fatty acids your dog needs to be healthy.
CONNECTED: Why your dog needs more omega-3s …
What Omega Fats Does Your Dog Need?
There are many different omega-3 and omega-6 fatty acids that your dog will need in their diet. Common omega-6 fatty acids and their sources include:
- Linoleic acid (LA) – Omega anti-inflammatory fat associated with healthy skin and coat.
- Gamma linolenic acid (GLA) – an important anti-inflammatory agent found only in vegetable oils. It helps with your dog’s skin, coat, and hormone control.
- Arachidonic acid (AA) – triggers the inflammatory immune response. If your dog gets too much AA or other inflammatory fats, it can lead to chronic inflammation.
Common omega-3 fatty acids and their sources include:
- Eicosapentaenoic acid (EPA) – an anti-inflammatory agent that competes with anti-inflammatory omega-6 fatty acids to improve the immune response.
- Docosahexaenoic acid (DHA) – Makes healthy cell membranes to keep eyes, brain and nervous system healthy.
- Alpha Linolenic Acid (ALA) – Converted to EPA and DHA. It can also improve heart health, immune response, and the nervous system.
- Stearidonic acid (SDA) – an anti-inflammatory fat that keeps the heart healthy. SDA also converts to EPA and DHA more efficiently than ALA.
- Eicosatetraenoic Acid (ETA) – a powerful anti-inflammatory agent that modulates the immune system and helps restore cartilage.
You are probably familiar with many of these sources of omega-3 and omega-6 fats. Especially oils from algae, phytoplankton, flax seeds, camelina, hemp seeds, fish and krill. But cauliflower is more beneficial than all of these oils. Here’s why …
Why is Ahiflower better than other oils?
Ahiflower is a nutritional omega powerhouse in a small package. It’s high in SDA that converts to EPA more efficiently than other oils. And EPA is one of the most researched omega fats, offering anti-inflammatory and immune boosting properties.
Ahiflower Oil is also full of GLAthat most other oils lack. This is important because GLA is vital to your dog’s health. And it’s almost impossible to provide too much GLA.
While there are many sources of omega fatty acids for your dog, cauliflower oil offers more nutritional benefits than other oils. Just look at how cauliflower oil compares to other known vegetable and ocean based oils.
Ahiflower Oil against fish or krill oil
- Ahiflower oil contains 5-8% GLA, while fish and krill oil have no GLA.
- Fish and krill oil are neither vegan nor vegetarian.
- Fish and krill oil can cause unpleasant, fish-tasting burps Ahiflower has a neutral taste.
- Ahiflower oil does not cause overfishing of the ocean.
- Fish oil can contain heavy metals or toxic chemicals. Ahiflower doesn’t.
Ahiflower Oil vs Flax Oil
- There are 18-20% SDA in cauliflower oilcompared to flax oil without SDA.
- Flax oil also contains 0% GLA. Ahiflower contains 5-8% GLA.
- Ahiflower Oil has 76.2% higher adjusted levels of omega-3 and omega-6. (Adjusted amount – SDA increased to reflect improved transition to EPA compared to ALA.)
- Ahiflower oil is 400% better than flax in converting GLA to EPA.
Ahiflower Oil vs Microalgae Oil
- Microalgae oil is more expensive than cauliflower oil.
- Ahiflower oil is more sustainable, not genetically modified and comes from land rather than water.
- Microalgae have a total of 0 omega-6, compared to 18% omega-6 compared to cauliflower oil.
Ahiflower Oil versus Chia Seed Oil
- Ahiflower oil has 18-20% SDA compared to 0 SDA in chia seed oil.
- Chia seed oil has 90% GLA compared to 5-8% GLA in cauliflower oil.
- Ahiflower oil has a 55.7% higher adjusted total omega-3 and omega-6 than chia seed oil.
Ahiflower Oil vs Hemp Oil
- Ahiflower oil contains ten times more SDA than hemp oil.
- Ahiflower oil contains 60% more GLA than hemp oil.
- Ahiflower oil has a 40% higher adjusted total omega-3 and omega-6 than hemp oil.
Ahiflower Oil versus Echium Oil
- Ahiflower Oil contains 60% more SDA than Echium Oil.
- Ahiflower oil is cheaper and more affordable than echium oil.
- Ahiflower oil has 30.4% higher adjusted total omega-3 and omega-6 than echium oil.
And ahiflower oil contains more than twice as much omega-3 and omega-6 as borage and sea buckthorn.

Ahiflower is sustainable choice
Sustainability is important – there is only one earth. And it’s not sustainable to constantly deplete the ocean of small fish to make products like fish oil.
Fish oil comes from foraging for fish species such as anchovies, sardines and mackerel that are harvested in the wild. Some brands that sell fish oil use sustainable harvesting methods, but not all companies. This means that fish oil is not completely sustainable, which harms these fish and disrupts the fragile, natural ecosystem of the ocean.
Ahiflower is a much more sustainable choice.
One hectare of Ahiflower provides omegas that are equivalent to 320,000 anchovies or 100,000 sardines. This means that Ahiflower has more nutrients and takes up less space than fish oils.
Ahiflower oil is also regenerative and enriches the soil on which it grows. Agriculture and the cultivation of Ahiflower promote soil fertility and biodiversity. And it supports the diversity of pollinators that are essential for the survival of fruits, vegetables, and other plants.
How to give Ahiflower Oil to your dog
Giving your dog cauliflower oil is safe and easy! It has a mild, earthy taste and is not known to react to any cauliflower oil. And it’s available in liquid form or in capsules.
- Liquid: ¼ tsp per 20-25 pounds of body weight. It is recommended to mix oil in wet or dry food (with added water). Once opened, you can store a cauliflower oil refrigerated to extend its shelf life and keep it fresh.
- Capsule: 1 capsule (750 mg) for every 15 pounds of body weight.
Learning omegas can seem daunting, but it doesn’t have to be. Read The Ultimate Guide To Fats In Dogs To Learn More About What Fats Your Dog Needs And How To Give Them.
