Why does krill top the best brain food for dogs list?



Sure, it contains omega-3 and choline, both of which are proven to support and improve dogs' cognitive functioning. Then again, plenty of other ingredients include these, too.

What makes this Antarctic find so special?


Krill: the most effective agent of delivery 


In our last blog we discussed bioavailability: if the ratio of nutrients in your pooch's food isn't right, they can't absorb them properly, no matter how healthy the meal. Something similar occurs when feeding your dog powerhouses omega-3 and choline: if they're supplied in the wrong form, your pet will see few to no benefits. Sadly, this is often the case, and their presence in most pet foods is little more than a marketing ploy.


Not so when krill is the agent of delivery. Arguably the most potent brain food for dogs, this mighty ingredient can have a major impact on your hound's mental and physical wellbeing. Here's why:


There's omega-3… and then there's omega-3


A raft of evidence demonstrates how critical omega-3 is for maintaining great canine health, from puppyhood right through to old age. What many people don't know is that omega-3 fatty acids come as long-chain omega-3s or short-chain omega-3s - andthe difference between the two is big. 


Long-chain omega-3s are linked with all the health-boosting benefits we know of: not short-chain omega-3s. The type of omega-3 fed hugely impacts the rate at which it raises a dog's omega-3 index: how we measure the amount of good fatty acids in a dog's red blood cell membranes.


QRILL Pet, our Antarctic krill supplier, cites a study of twenty Alaskan Huskies as an example of this in action. Over six weeks, ten Huskies were given krill oil, a known source of long-chain fatty acids; the other ten were given flaxseed oil, a source of short-chain fatty acids.



The Huskies started with similar omega-3 index levels. In as few as three weeks, those ingesting krill oil showed markedly higher omega-3 index levels, while those receiving flaxseed oil showed a notable decline. 


By week six, the omega-3 index levels in the Huskies dining on krill oil remained significantly raised, while the index levels of those on flaxseed oil continued to deplete. In the end, the krill group saw a 62% hike in their omega-3 index and the flaxseed group saw a 40% drop. Pretty hefty gap.


Krill as a brain food for dogs: omega-3 benefits


So, we've established that krill is a top notch brain food for dogs - one that properly provides the omega-3 goods. Here are some of the benefits its long-chain fatty acids offer your canine:


Cognitive support

Omega-3s are vital for the maintenance of cognitive function, especially during a dog’s early and senior years.


The long-chain omega-3 fatty acids in krill help pups develop and support older hounds' mental faculties, making krill an ideal brain food for both age groups, in addition to ultra active dogs such as the Huskies QRILL Pet studied.


Happy hearts

Frequent consumption of marine omega-3s has been linked to improved heart health, decreasing the risk of disease and combatting inflammation. 


Strong muscles and joints

Another standout feature of the omega-3s found in krill is their anti-inflammatory effect on muscles and joints, perfect for growing pups, ageing canines, and high-performance dogs.
