7 Best Krill Oils for Dogs in 2026 - Reviews & Top Picks

Fish oil has been a popular supplement for pets and humans alike for a long time, though the type of fish oil that is best has always been up for debate. While people swear by cod liver oil, others argue that wild Alaskan salmon oil is the only acceptable fish oil.

Krill fish oil slowly growing in popularity, and it's for a good reason. Krill is naturally toxin and mercury-free, so it's safer and cleaner than other fish. However, it can be difficult to find the right krill oil supplement for your dog.

There are many products available that have different benefits and features that may influence your decision. Thankfully, we’ve done the hard work for you. We found the highest quality krill oil supplements and made a list of our in-depth reviews. Here is our list of the best krill oil for dogs this year.

The 7 Best Krill Oil for Dogs

1. NaturVet Hemp Seed, Krill, & Salmon Oil – Best Overall

NaturVet Hemp Seed, Krill, & Salmon Oil is a dog and cat supplement that provides a healthy and natural source of omega-3 and omega-6 fatty acids. It contains antioxidants, too, to help ensure your dog’s coat and skin not only look good but feel good.

The ingredients also help maintain good bone, joint, and muscle health while improving their respiratory condition. It can prove very useful for dogs that suffer from allergies, or struggle to breathe during the summer months. It is competitively priced, easy to feed by adding a teaspoon to meals, and contains natural ingredients. If you’re looking to supplement an existing diet, or are looking for a method to improve your dog’s skin and fur condition, we found NaturVet to be the best overall krill oil for dogs, especially because of its natural ingredients. The only real issue is that the oil combines fish oil and hemp oil, which gives a somewhat pungent aroma. Despite, this we think this is the best krill oil for dogs available this year.

2. Grizzly Pet Products Krill Antioxidant – Best Value

Grizzly Pet Products Krill Liquid Antioxidant is a liquid krill oil supplement for dogs that need an extra nutrient boost in their diets. Made with wild Antarctic krill, this liquid supplement has a natural taste that your dog will love.

This liquid krill oil is rich in omega-3 and omega-6 fatty acids, which are essential nutrients for your dog’s immune system. It helps nourish the skin and coat to prevent dry skin, giving your dog the relief from constant itching. This oil is also less expensive per dose than other fish oil supplements, saving you money in the long run.

However, it does have a strong fishy odor, which can be a dealbreaker for some people. The pump can also be hard to use, which is a pain for liquid-based supplements. For these reasons, we kept it out of our #1 spot. Otherwise, we find the Grizzly Pet Products Krill Liquid Antioxidant to be the best krill oil for dogs for the money.

3. Dr. Mercola Antarctic Krill Oil Liquid

Dr. Mercola Antarctic Krill Oil is a liquid krill fish oil supplement in an airlock pump bottle that gives around 100mg doses per pump. This krill oil supplement is made with sustainably sourced Antarctic krill that contain no mercury or other dangerous toxins, while also being more nutritious than other fish oils.

It also contains essential fatty acids, which are necessary for your dog’s overall heart and brain health and wellness. It also helps nourish the skin and coat from the inside, so it may help with itching and other common skin conditions.

Although the bottle design is unique, the faulty pump jams way too easily and leaks krill oil everywhere. It has a strong fishy odor because it’s a liquid supplement, but it seems stronger than other brands.

It’s also more expensive than other kill oil per dose, which can add up quickly for bigger dogs. If you have a small dog and don’t mind the stubborn pump, Dr. Mercola Antarctic Krill Oil Liquid can be a good option.

4. Zesty Paws Krill Fish Oil for Dogs

Zesty Paws Krill Fish Oil for Dogs is a krill oil supplement to give to your dog daily for skin, coat, and immune system support. It’s made with a blend of krill oil, krill meal, and hemp for multiple health benefits and essential nutrients.

These come in a convenient bite-sized treat to make it easier to dose, with no messy liquids to handle. They’re also on the less expensive side than other krill oil supplements, saving you money in the long run. While they’re not as messy as liquids, these have an intense smell for a chewable that may not be pleasant to handle.

The bacon flavor of the Zesty Paws Krill Oil is not impressive, with some dogs not liking the taste. It may also be too rich for some dogs, which can lead to indigestion.

5. Hanzi Pets Antarctic Krill Oil Soft Chews

Hanzi Pets Antarctic Krill Oil Soft Chews are premium low-calorie krill oil soft chews. They’re made with Antarctic krill free of the toxins and pollutants that other fish have, which can be harmful to your dog’s health.

These chews contain vitamin E, an important nutrient that helps promote a shiny and soft coat. They also help reduce itching from dry skin, which can be irritating and painful for your dog. However, the Hanzi Pets Antarctic Krill Oil Soft Chews are lower in nutritional value per dose than other supplements, so your dog may not experience the full range of health benefits.

They’re more expensive per dose as well, which adds up quickly for medium and large dogs. These soft chews tend to crumble when they’re cut in half for toy-sized dogs, which makes proper dosing a nightmare. If you're looking for high-quality krill oil, we recommend trying one of our top two picks for a more nutrient-dense, less expensive krill oil supplement instead.

6. Pet Vitamin Co Krill Oil Shed-Free Chews

Pet Vitamin Co Krill Oil Shed-Free Soft Chews are krill oil supplements specifically designed for dogs that shed and scratch excessively. They may help reduce shedding and itchy skin, made with vitamins and minerals that help heal dry and irritated skin.

These soft chews contain vitamin E, which can help soften and brighten the coat. They also have a flavorful taste that most dogs like, so they can be good for dogs that tend to be picky. However, they are low in nutritional value compared to other krill oil supplements, which can make these expensive for long-term use.

Pet Vitamin Krill Oil Soft Chews are rich in flavor, so they may not be suitable for dogs with sensitive stomachs. They’re also hard to cut for proper dosing, which can also make your dog’s stomach upset or sour. For a more nutritious supplement without causing digestive issues, we recommend trying Grizzly Pet Products Liquid Krill Oil instead.

7. Max and Morgen Krill Oil Soft Chews

Max and Morgen Krill Oil Soft Chews are krill oil supplements that are aimed at reducing overall shedding. They have a tasty cheese flavor that most dogs seem to enjoy, so picky dogs are less likely to refuse them. They also have less odor than liquid fish oil, making them less unpleasant to handle.

However, these soft chews are not very soft and are hard to chew for some dogs. They also crumble when being cut, so they’re not recommended if you have smaller dogs since dosing them properly will be difficult.

Max and Morgen Krill Oil Soft Chews contain a low dose of krill oil, which makes them less of a value than other krill oil supplements. The krill content of these chews is too low for your dog to gain any benefits, so they don’t help with dry or itchy skin. We recommend trying other krill oil supplements for better results and higher quality for your money.

Buyer's Guide - Choosing the Best Krill Oil Supplements for Dogs

When it comes to choosing krill oil for your dog, it can be difficult to decide which product to choose especially when there are so many great options on the market. It helps to first consult with a veterinarian, who can recommend some great products based on your dog's needs and your budget. But here are some other things to keep in mind when choosing a krill oil supplement for your dog.

Administration

The first thing you want to consider is how the supplement is administered. Do you want a liquid supplement that you can pour over your dog's food or feed them through a dropper, or do you want a capsule or pill that your dog has to swallow? For most people, unless you know that your dog takes pills will, it may be easier to go with a liquid krill oil supplement that you can just drop over their food.

Budget

Of course your budget is an important consideration, because if you're going to use a product for a long time, you want to be able to afford it for a long time. If a product is expensive, you may not be able to afford it in the long run, so make sure you choose an affordable but effective product. The size of your dog should also be taken into consideration, because the bigger your dog is, the higher the dosage, which can effect how often you buy the product.
