The 9 Best Krill Oils for Dogs

1. Bark Bistro Krill Oil Chews for Dogs – Best Overall

Bark Bistro Krill Oil Chews is our choice for best overall krill oil for dogs, and you might agree! Soft chews really get your pups’ appetite—they are moist and tasty (our pups told us so.)

These treats are made in the United States, using ingredients alongside other additives. The formula was designed to nourish your dog’s system and improve skin and coat, and the primary point of the product is to reduce shedding.

In addition to omega fatty acids, this product also contains a terrific antioxidant called astaxanthin. Rigorous testing is done to ensure that there are no toxic substances inside these treats.

2. Hanzi Pets Tru Krill Antarctic – Best Value

If you’re looking for the biggest bang for your buck, check out Hanzi Pets Tru-Krill. We looked at all and feel that these chews are the best krill oil product for dogs for the money. Your dog will enjoy the daily dose of fishy flavor and you will notice the results!

This product contains 100% organic krill from Antarctica. Each treat contains 18% crude protein, 24% crude fat, and 5% crude fiber. A feeding chart on the back tells you how much you should give your dog per day.

This product is very straightforward, targeting itchy skin and shedding. This product is guaranteed free of toxins – specifically mercury, PCBs, and heavy metals. So, you can happily know you’re giving your guy or gal the good stuff.

3. NWC Naturals Tri-Krill – Premium Choice

We love NWC naturals Tri-Krill Antioxidant Dog Supplement. It is formulated to work in your dog’s system and includes feline friends. So if you have a multi-pet household, all of them could benefit.

This particular brand comes in a small dispenser with a pump. You can pump out the portions into your dog’s food or treats to make the eating process seamless. Rationing is simple. You simply pump for every 10 pounds of body weight. Your dog can benefit from the omega fatty acids, DHA and EPA.

This product has an airless pump design, making distribution a breeze. It has a natural krill taste with no additional flavor, which can enhance an existing meal. It also has 100% genuine AsaREAL astaxanthin, a patented antioxidant to fight free radicals in the body.

What we love most about this product is how much you get. It looks pricey initially, but when you consider how far this product stretches, it is definitely worth it for some pet parents.

4. Wonder Paws Fish Oil

If you have a puppy, we have to recommend Wonder Paws Fish Oil. This type of krill oil can be added to any diet, but it has a concentrated dose of DHA and EPA, which aids in your pup’s brain and cognitive development.

In addition to krill, this is a power-packed trio containing wild-caught Alaskan salmon and cod—two additional supplements high in omega fatty acids. It also contains astaxanthin oil, which is an ultra-powerful antioxidant.

This product really helps soothe itching, irritation, and abrasions from allergies, but it targets joint and immune health, too. So, it’s a terrific supplement to give your pup, enhancing daily nutrition.

This product is GMP-certified and made in the USA.

Since this is an oil you can add to regular meals, this cuts back on the risk of your dog not liking other krill products, like soft chews. It would help if you only gave this to your pup while symptoms persist. Once you see that their coat is shiny and their skin is blemish free, cut back for the time being.

All-in-all, we highly recommend this product and think you will love it, too.

5. Pet Vitamin Co Krill Oil

We really enjoyed giving our dogs Pet Vitamin Co Krill Oil Soft Chews. This particular kind of krill oil could help dogs with mobility problems, as it serves the joints and connective tissues. So, if your dog isn’t quite getting around how they used to, this could also help in that area.

We were impressed with the size of these treats. They are perfect for breaking in half and splitting up throughout the day. So if you have a senior, this can help with the overall joint range of motion and soothe issues like arthritis and other age-related problems.

The cheesy fishy flavor is sure to appeal to your dog’s senses. It will be like a regular yummy reward. Your dog will happily sit, tails a waggin’, waiting to get a bite.

Good for any age, these soft chews definitely work for the intended purpose. Or you can serve it to your dog in one swoop, using the serving instructions located on the back of the package. Each treat is made right here in the USA with healthy, traceable ingredients that you can count on.

6. Krill MAX Fish Oil for Dogs

Krill MAX Fish Oil for Dogs is terrific for dogs of all ages and with all dental conditions. They’re soft enough for dogs that are aging to chew up. It’s made with very high-quality krill oil replacements with lesser quality sea-caught products.

These little chews have a lot to offer—packed with essential vitamins, minerals, oils, and antioxidants. Healthy and tasty, these cheese-flavored treats are sure to be a hit with your pooch. All ingredients are completely natural and made in the USA.

This particular chew targets shedding decrease, creates healthy skin and coat, boosts joint support, and aids in heart and brain function. Of all the krill oil products on our list, this one definitely has tons of added benefits.

But since this targets so many health areas, it might take away from a target tissue. Say, for example, your dog has an allergy. You might want a krill product that targets allergies explicitly—and this isn’t the one for that.

7. Dr. Mercola Antarctic Krill Oil Liquid

Dr. Mercola Antarctic Krill Oil Liquid deserves some serious recognition. This oil is a cure-all, treating cardiovascular, vision, joint, and bone health systems. The way that they market this product is to target several different health areas in the body, including creating a healthy coat and skin, but that’s definitely not all.

This company formulates this particular product for maximum absorption. It contains a bountiful list of ingredients including vitamins A, E, astaxanthin, and canthaxanthin. That means your dog is getting the most out of the contents.

You can easily pump the recommended dosage into a bowl with their regular kibble. This product is a little on the expensive side, so make sure you pay attention to quantity and consider it before purchasing. It has a mess-free pump design to make things easy and tidy.

We really love the ownership the company takes over their product. They are so certain of it, they even put their GPS coordinates on the label. You can trace any ingredients and check any part of the product you wish. The transparency is much appreciated—and approved by the Marine Stewardship Council.

8. Max & Morgen Pure Krill Joy

Max & Morgen Pure Krill Joy targets the improvement of allergies. We think that these treats are both effective and tasty – so do our pooches. This treat will definitely cut back on your pet’s allergies, but it will also reduce shedding and dander on your pet.

These chews are easy to dish out, following the weight chart on the back. In a few weeks, you’ll really start to notice the shiny coat and healthy skin of your pup.

These chews are considered an eco-friendly, natural product—certified on the label. So, if you have concerns about questionable ingredients, they have a solid reputation for healthy products. These treats can be offered daily and are considered “low-allergen.”

The only downfall here is that they do contain a novel synthetic flavor.

9. Zesty Paws Krill Cognition Bites for Dogs

Lastly, we have Zesty Paws Krill Cognition Bites. We have to give the product props right off the rip—it has more chews than any other product on our list. Considering the price, this deal is very fair! They work, too. Many happy customers report improvement in their dog’s cognition—and we must agree.

These soft chews have a lot to offer, containing “qrill,” DHAgold, and other enhanced ingredients. It also contains organic hemp, which is supposed to soothe skin itching and irritation. It also targets joint health and mobility, bringing life back into pups that have trouble with movement.

These chews are bacon flavored, so they should appeal to the palate of any pooch—but be mindful of allergies. The natural bacon flavoring isn’t specified, so sensitive dogs might have adverse reactions to the formula, but it looks like a clean list otherwise, with globally sourced ingredients.

Complete Benefits of Krill for Dogs

Krill, alongside other sea creatures, has a very high omega fatty acid content. These components nourish the skin and coat, helping promote healthy oils for healthy skin—but that’s not all.

Krill has natural antioxidants and other goodies. Plus, lots of companies enhance their products to include vitamins, minerals, and other improvements.

Effectiveness

Krill can be an excellent source of nutrients that definitely benefit your dog’s health. But some products are more effective than others. Often, this is due to the quality of sourced ingredients, overall recipe composition, and enhancements or additional ingredients.

Types of Krill for Dogs

Krill comes in two main forms for dogs—treats or dispensable oil. Either one is beneficial for your pooch, so it really comes down to preference.

Oil

In oil form, you can easily add it to your dog’s traditional food. It is usually flavorless, blending in with the food you mix it with. It will carry the natural fishy flavor, as this is a sea-sourced product. But this type can certainly sneak past a picky pup’s radar.

Oil is a more concentrated version of the substance, so a little goes a long way. From our experience, the oil stretched more for the dollar compared to chews.

Krill oil can contain other ingredients, like additional fish oils, vitamins, minerals, antioxidants, and other perks. Some concoctions can be used for target areas, usually joints, heart, cognition, and allergies.

It’s typically best to buy oil in pump form, as pouring it can get messy quickly!

Chews

Chews could be a more profitable way to let your pup enjoy the benefits of krill oil. Chews can come in different flavors, but most generally, you will see cheese or bacon. These are specially formulated to appeal to a dog’s taste buds, making them more likely to indulge.

This type of krill can double as a reward. So, your pup will think they are getting a delicious snack, but really it’s a health enhancer—everyone wins.

In our experience, krill tends to be a little more expensive when it’s in chew form. So, if you are looking for something to last, you should closely compare the two to see how much you’d be saving in either direction.

Chews can combine krill with other ingredients to target specific areas of health. Be more mindful of the ingredients here, as certain ones can trigger allergies in sensitive pups.

Krill Oil: Full Benefits

Krill oil doesn’t have a primary focus. It basically helps “oil” your dog’s hinges, so to speak. It can work fabulously for dry, irritated, cracked skin or brittle, dull coats. It can also help with mobility by strengthening joints and muscles.

Omega Fatty Acids

Omega fatty acids are what make sea oils like krill really work for the skin. These excess omega 3 and 6 elements help create natural oil production, enrich the coat, and improve the skin. Often, you can find a wallop of omegas in allergy-soothing products for canines due to these qualities.

Antioxidants

Krill oil (permitting it isn’t too diluted) contains favorable antioxidants that remove free radicals from your dog’s body.

DHA

DHA is a significant part of brain development. It is both essential and terrific for puppies during the growth stages. However, it also helps adults and seniors with mental maintenance.

EPA

EPA is a cold-water fatty fish compound. It helps lower the risk of heart disease and is one of many omega-fatty acids. It can decrease inflammation and help with age-related issues like arthritis. It can also aid in pup development.
