Omega-3 and Omega-6 Ratio in Pet Food

Pet food is often high in Omega-6 but low in Omega-3. Too much Omega-6 and too little Omega-3 can lead to several health problems for your dog or cat. The difference between Omega-3 and Omega-6 fatty acids is based on molecular structure. A ratio of about 4-1 Omega-6 to Omega-3 is considered optimum for dogs but many commercial dog foods contain ratios of 20-1.

Omega-6 vs. Omega-3 imbalance may lead to:

  • Inflammation
  • Allergy like symptoms
  • Pour coat or skin
  • Joint problems
  • Overweight and obesity

But why is there too many Omega-6 in my pet diet?

Most live-stock is grain-fed, which is high in Omega-6. Since most pet foods including raw food contain much more Omega-6 fatty acids than Omega-3 fatty acids, many pet food companies have added Omega-3 fatty acids to try and compensate for this difference.  However, the cooking and processing of most commercial pet foods does destroy some of the fatty acid content. Supplementing with a bioavailable Omega-3 can restore the balance.

Why Seal Oil?

The best Omega-3 / Omega-6 Ratio

A concrete example comes to us from Norway where a study (Bjørkkjær et al. 2006) clearly concluded: “… administration of seal oil normalised the n-6 to n-3 Fatty Acid ratio and improved the bodily pain dimension of health related quality of life of patients ….”

The ratio of SeaDNA Omega-3 Seal Oil is almost 8:1 in favour of Omega-3, an excellent balance to help promote better overall health. And as science has shown us, seal oil is proven to improve the critical Omega ratio.

Contains DPA

Seal Oil contains the link in the Omega-3 chain that all other Omega-3 supplements now sold are missing: DPA (docosapentaenoic acid). This compound occurs naturally in few places: Seal Oil and a mother’s breast milk are two.  DPA amplifies the positive impact that EPA and DHA can have on your pet.

More easy to absorb

Scientific studies have shown that the mammalian molecular triglyceride structure of the seal is more easily accepted by your pet’s body than the foreign fish molecular structure. This means optimal digestion and absorption for better results.

10 X More efficient

A scientific study has shown that the maximal stimulation of endothelial cell migration by DPA pre-treatment was achieved using only 1/10 of the required EPA concentration.  These data suggest that the effect of EPA on endothelial cell migration occurs via DPA, and that DPA plays an important role in repairing damaged vessels.

So the answer to the question “Will Omega-3 help my pet” is: “Phoque” Yeah!

There isn’t anything we wouldn’t do for our pets. They are part of our family and enhance our lives daily. We know this very well at SeaDNA and this is why we have created SeaDNA Omega-3 Seal Oil for Pets – so you can help enhance the life of your little beastie! We are beyond excited about this next stage of our mission to bring the best in Omega-3 to as many people and now pets as possible. 



Seal Oil has the power of 3 fatty acids: DPA + EPA + DHA. DPA occurs naturally in a few places. Seal Oil and mother’s breast milk are two. DPA increases overall Omega-3 retention and it intensifies the benefits of traditional Omega-3’s (DHA & EPA).


The mammalian molecular triglyceride structure of the seal will be more easily assimilated by your pet which means optimal digestion and absorption for better results.


Our seal oil comes from pristine and icy waters surrounding the Magdalen Islands and the coast of Newfoundland. Seals represent an abundant and renewable resource and their harvest is part of a responsible and sustainable marine ecosystem management.


Sourced and made right here in Canada, SeaDNA Seal Oil for Pets is processed to the same high standards as our human Omega-3 products and provides the same health supporting attributes.


Along with all these other good things, SeaDNA Seal Oil for Pets can also act as an appetite stimulant for those pets who may not always jump for joy at their usual food. The natural seal oil taste of our pet Omega-3 is one our dogs just can’t deny!


There are many benefits an Omega-3 can provide to a pet, but one of the biggest is the ability to fight inflammation. Inflammation is often directly tied to allergies in pets and many common skin and dander issues. Omega-3’s have been found to help in cases of dry skin and other similar disorders. Science has shown clearly that fatty acid supplementation has huge benefits.

There are many studies that have been done, but perhaps the clearest conclusion came from these ones:

Omega-3 fatty acid-enriched diets can be used to control inflammation associated with dermatologic conditions.”

Dogs receiving marine oil showed a significant improvement in pruritus […],self-trauma […] and coat character […] over time. When compared to the corn oil control over time, marine oil supplementation significantly improved pruritus […], alopecia […] and coat character […]. This study demonstrates the effectiveness of high doses of marine oil as an alternative anti-inflammatory for canine pruritic skin disease.

Omega-3 also works for cats: “[…] fish and flaxseed oil can reduce skin inflammatory responses in cats, however, flaxseed oil appears less immunosuppressive than fish oil.

 This means that if your pet has these issues an Omega-3 could be a life-changer for them.


There are numerous other benefits that have been tied to Omega-3 usage in pets which has veterinary professionals turning to them as a natural treatment for animals more and more. One that has been looked at and studied right here in Canada is mobility issues in dogs.

Researchers at the University of Montreal were able to determine that adding Omega-3 to a dog’s diet resulted in significant improvement for those having issues moving around. This study as compared the effect of a diet rich in omega-3 fatty acids compared to a regular diet over a period of 13 weeks in dogs afflicted by naturally occurring osteoarthritis:  “In lame occurring osteoarthritis dogs, a veterinary therapeutic diet that contains high level of omega-3 from fish origin improved the locomotor disability and the performance in activities of daily living. Such nutritional approach appears interesting for the management of osteoarthritis.

Another study concluded, “According to owners, dogs fed the [Omega-3 supplemented] food had a significantly improved ability to rise from a resting position and play at 6 weeks and improved ability to walk at 12 and 24 weeks, compared with control dogs.

Another study conducted on cats has shown that: “Cats on the fish oil revealed higher activity level, more walking up and down the stairs, less stiffness during gait, more interaction with the owner and higher jumps compared to those on corn oil supplementation.

If your family pup or kitty is getting older SeaDNA Omega-3 for pets could help ensure their later years are as good as possible.


This is one of the most well-known benefits for humans. And wouldn’t you know it, Omega-3’s can also have huge benefits for pets as well! Once again, science has investigated and come to the conclusion that Omega-3’s aren’t just helping pets, in some cases they could even be life-savers.

In general, the studies show that adding more fatty-acids to your pet’s diet can help for common issues like arrhythmia:

Long chain n-3 polyunsaturated fatty acids reduce atrial vulnerability in a novel canine pacing model.

EPA may ameliorate the decrease in adiponectin and the increase in insulin and triglyceride concentrations in obese cats. (Mazaki-Tovi, 2011)

If your dog or cat has heart issues it is certainly time to look into Omega-3’s.


This all comes back to the ability of Omega-3’s to target inflammation. Many immune system disorders in both humans, dogs and cats are related to inflammation and seal oil is very powerful at fighting this. Essential Fatty Acids like seal oil remain important mid-life and then later throughout the aging process, as they have a positive effect on the immune system:

Long-chain omega-3 fatty acids from fish oil and other marine sources appear to be capable of modifying inflammatory and immune responses in dogs.

Dietary Fatty Acid can modulate leukotriene production by neutrophils in dogs, and suggests that foods enriched in (n-3) FA from fish oil may have value in the treatment of canine inflammatory diseases.


An Omega-3 supplementation (especially DHA) is beneficial beginning with gestation and early development and is important for neurological and retinal growth:

Long-chain omega-3 fatty acids from fish oil and other marine sources appear to be capable of modifying inflammatory and immune responses in dogs. Information is provided on the capacity of dogs to metabolize omega-3 fatty acids and the effects of omega-3 fatty acids on […] neurologic development in puppies.

These findings indicate that preformed dietary (n-3) LCPUFA is more effective than ALA in enriching plasma DHA during perinatal development and results in improved visual performance in developing dogs.

Feeding dams a diet enriched with DHA during gestation and lactation has been associated with improvements in neurologic development of their puppies. Also, feeding diets or supplements containing DHA may improve memory or learning in young dogs.

These findings suggest that in juvenile felines, maintenance of 22:6n-3 status in the nervous system is important for optimal retinal function.

Therefore, any dog or cat breeder or any person who intends to get a puppy or a kitten in the near future should get a bottle of Omega-3 Seal Oil!

So, we’re shown you clearly that the science is in: and Omega-3 Seal Oil will help your dog or cat live a better life from day one to that unfortunate time we have to say goodbye. In between, SeaDNA Seal Oil can ensure that you and your cherished animal can enjoy as many great times together as possible. And really, that’s what it’s all about.

It doesn’t take much to make a huge difference!
