Now let’s dive in and learn more about each product and the company that stands behind it.

K9 Nature Supplements Hip and Joint Revita Chews

star 9.7

For Canines with Arthritis

  • Form: Chewable tablets
  • Potency: 150mg of omega-3 fatty acids per chew
  • Origin: US-made at an FDA-approved and cGMP-certified facility
  • Flavor: Chicken
  • Quantity: 60 chews per bottle

The K9 Nature Supplements hip and joint chews can improve your pet’s mobility and posture, relieve pain, and restore healthy joints.

Their unique blend of 100% natural active ingredients include glucosamine and chondroitin sulfate. These dietary supplements are used for the treatment of osteoarthritis. Therefore, even an aging dog might run, walk, and play like a puppy once more.

Besides repairing joints and easing pain, the combo of glucosamine and fish oil for dogs ensures that your dog’s coat, heart, and brain stay healthy.

Each K9 Nature Revita chew contains 150mg of omega-3 fatty acids (derived from fish oil)—the ideal dosage for a medium-sized dog such as a Dalmatian or Bull Terrier.

If your dog is bigger, administer two chews—with 60 pieces per bag, and you’ll have more than enough for the entire month.

The chews taste great and are soft and small enough for dogs of all sizes and breeds. Most of the user reviews on K9 Nature Supplements rave about the effects of these chews on their senior dogs, although both young and older doggies can use them.

Active ingredients: Glucosamine, chondroitin sulfate, methylsulfonylmethane, omega-3 fatty acids (from fish oil), manganese

Other Products to Complete Our K9 Nature Review

We suggest giving the brand’s Nature’s Aches Away a try if your dog has sensitivities to glucosamine or MSM.

This dietary supplement is 100% natural and offers many of the same benefits as the K9 Nature Hip and Joint Revita chew. It also contains fewer ingredients (cat’s claw root extract and willow bark extract) and has a slightly higher fish oil content, too (160mg per chew).

K9’s Nature’s Aches Away provides an effective and natural remedy against arthritis and hip dysplasia and instant relief from aging discomfort.


  • + 100% natural
  • + Recommended by vets

Nordic Naturals Omega-3 Pet Soft Gels

star 9.8

The Top Brand in the Market for Canines

  • Form: Gel tablets
  • Potency: 1000mg of fish oil per soft gel (165mg EPA, 105mg DHA)
  • Origin: Made in Norway, bottled in California
  • Flavor: Unflavored
  • Quantity: 90 or 180 count

Nordic Naturals implements the highest quality, safety, and purity standards in both their human and pet products.

Therefore, it’s not surprising that their Nordic Naturals Omega-3 for Pets product line is one of the best-rated pet supplements by consumers and experts alike.

Nordic Naturals fish oil is sustainably-sourced. Derived from wild-caught anchovy and sardines, the company ensures using the freshest catch from the cleanest waters.

What’s more, the Nordic Naturals Pet Omega-3 formula contains fish oil in its natural triglyceride form for maximum absorption and the fastest effects.

Each softgel contains 1000mg of pure fish oil—the ideal dosage to boost your dog’s immune system and promote heart, joint, and coat health.

These supplements come in three bottle options (90, 120, and 180 ct), so you can choose the quantity based on your dog’s size. The price might be higher on the Nordic Naturals Omega-3 Pet 180 ct softgels, but this pack will last you for over a month, even if you have a giant breed like a Great Dane.

Nordic Natural softgels are unflavored (for optimal safety and effects). The fishy taste doesn’t usually go down well with dogs, but owners can easily puncture the gel covering and mix it in with their pet’s canned food or kibble.

All the brand’s products are third-party tested for purity, with results exceeding even WHO’s high standards.

With such amazing features, it’s clear why more than one Nordic Naturals fish oil review describes this product as the perfect natural supplement. It offers relief for a wide range of conditions your furry companion may have—from allergies to heart murmur.

Ingredients: Anchovy oil, sardine oil, gelatin, water, glycerin, d-alpha-tocopherol

Other Products in Our Nordic Naturals Omega-3 Pet Reviews

Besides the softgels mentioned in our Nordic Naturals Omega-3 review, this brand manufactures an equally effective fish oil in liquid form.

Namely, the Nordic Naturals Omega-3 Pet Oil is made from the same natural ingredients as their softgels, and it offers many of the same benefits.

As the product is available in three sizes (2, 8, and 16-ounce bottles), pet parents can choose the potency according to their dog’s breed.

Dogs and owners love this fish oil. There are hundreds of Nordic Naturals reviews saying it works great for dogs and cats of all sizes.

Furthermore, pet parents can also surprise their furry friends with the Nordic Naturals Pet Cod Liver Oil. This award-winning Nordic Naturals omega-3 oil for dogs is made exclusively of wild Arctic cod. It’s crafted for medium and large breeds, so it’s convenient for households with multiple pets.

Being a natural source of vitamin A, cod liver oil is highly recommended by vets for developing and maintaining cognitive skills and eyesight in dogs of all ages.

Zesty Paws Pure Wild Alaskan Salmon

star 9.9

Top for Canines With Itchy Skin

  • Form: Liquid oil
  • Potency: 1100mg of omega-3 fatty acids (390mg EPA, 480mg DHA)
  • Origin: US-made at an FDA-registered & GMP-certified facility
  • Flavor: Salmon
  • Quantity: 8oz, 16oz, and 32oz

According to the Zesty Paws Wild Alaskan Salmon Oil reviews by pet owners, this is one of the best supplements they have ever given their canines.

With no artificial colors, flavors, or preservatives, this is a no-frills, simple and effective formula that packs a ton of benefits—from maintaining healthy hearts and improving cognitive abilities to helping with hip and joint issues.

Still, Zesty Paws Pure Wild Alaskan Salmon Oil for dogs truly shines when it comes to skin and coat.

Salmon oil, especially wild-caught from Alaska’s fresh and clean waters, is not just one of the best sources of omega-3 fatty acids, but it also keeps the skin hydrated and eliminates flakes, dandruff, sores, and bald spots.

With this in mind, it’s no surprise there are over 2,000 five-star Zesty Paws Salmon Oil reviews on Amazon alone, or that 94% of pet parents on Chewy recommend this product, saying that dry and itchy skin has become a thing of the past.

Nothing is perfect, though, and there are some complaints about leaky or faulty pumps. Still, the company has excellent customer support and is always more than happy to help with any issues.

Active ingredients: Salmon oil, mixed tocopherols

Other Products From Zesty Paws

If using Zesty Paws Wild Alaskan Salmon Oil for pets is too much of a hassle, the brand makes delicious Omega Bites derived from wild Alaska pollock. These chicken and bacon-flavored bites are great for skin and coat, and they are enriched with vitamins E, B, and C.

If you want more ingredients, you can give Zesty Paws Hemp Elements Omega Bites a try. Hemp has impressive benefits for canines, and pet parents are already taking advantage of the best CBD oils to make their dogs’ lives better. This combo of hemp and fish oil can further calm your pet and significantly contribute to their skin and fur health.

Another product that comes highly recommended by Zesty Paws fish oil chews reviews is the brand’s Aller-Immune Bites —the most natural way to boost your pup’s immunity against seasonal and environmental triggers.

There are plenty more options to choose from as Zesty Paws isn’t just one of the best fish oil brands for dogs—it’s also the most versatile.


  • + Simple and effective formula
  • + Rich in omega-3 and 6 fatty acids
  • + Great website
  • + Amazing customer support
  • + 100% satisfaction guaranteed
  • + Full transparency
  • + Variety of options

Grizzly Pollock

star 10

Top Supplement for Canines Skin and Coat

  • Form: Liquid oil
  • Potency: 22% of omega-3 fatty acids (12% EPA, 6% DHA) and 1.5% of omega-6
  • Origin: Sourced from the Bering Sea and bottled in Washington, USA
  • Flavor: Pollock
  • Quantity: 4oz., 8oz., 16oz., 32oz., and 64oz. bottles

Unlike most of the products that use salmon, sardines, and anchovies, this supplement is made using pollock oil. When it comes to the best fish oil for dogs, our reviews place this one high on the list.

Pollock is a more affordable alternative to wild salmon (costs about 20% less) but offers almost the same benefits. Pollock is a white fish, and even though it isn’t as rich in fatty acids as redfish, it does have high concentrations of EPA and DHA.

What other factors make this the best-rated fish oil liquid for dogs?

The pollock that Grizzly Pet Products uses is sustainably sourced. In other words, it isn’t farmed but comes from the pristine waters of the Bering Sea, near Alaska.

What’s more, the Grizzly Pollock Oil for dogs is gently extracted, meaning that the process is completely enclosed, ensuring the oil is kept in a vacuum from start to finish. The extraction method is unique, safe, and executed at modern production plants that only work with human-grade fish oil products. On top of that, it’s regularly tested for mercury and other heavy metals.

Thanks to the unique extraction technique, Grizzly Wild Alaskan Pollock oil has the highest ratio of omega-3 and 6, thus providing the very best of both worlds.

This dietary supplement is available in five sizes, so there’s something for everyone—from the smallest Pug to the massive Bullmastiff. The bottles are equipped with an easy-to-use pump, although many Grizzly Pollock Oil reviews report leakage.

Other complaints referred to shopping convenience. The company’s products are only sold at online and brick-and-mortar retailers approved by Grizzly Pet Products, so they might be harder to get than other items on our list.

On the plus side, numerous accounts by customers say that Grizzly Pollock Oil Supplement for dogs has worked wonders with their pets’ skin and fur, from stopping itching and reducing shedding to making the coat look lustrous and silky.

Active ingredients: Pollock oil, tocopherols

Other Grizzly Coat Products

In addition to pollock oil, this company is the proud manufacturer of Grizzly Wild Alaskan Salmon Oil , one of the most popular fish oil supplements for dogs.

Can’t decide between the two?

The company recommends using both in rotation feeding so your dog can experience the effects of the Grizzly Pollock Oil dog food supplement and a more comprehensive nutritional effect, courtesy of the Grizzly Wild Alaskan Salmon Oil for dogs.

Besides these, Grizzly Pet Products has several other product lines, including superfoods and treats.

They also have three new hemp-infused items for canines.


  • + Made from wild-caught pollock fish (not farmed)
  • + 13/14 ratio of omega-3 and 6 (the highest on the market)
  • + Reduces shedding
  • + Works great for your dog’s coat
  • + Sustainably-sourced
  • + Certified by the National Animal Supplement Council
  • + Available in five bottle sizes


  • Available only at authorized retailers
  • Some complain about the strong smell

Iceland Pure Salmon for Pets

star 9.7

Suitable for Canines With Kidney Disease

  • Form: 1118mg of omega-3 fatty acids per teaspoon (644mg of EPA; 414mg of DHA)
  • Flavor: Salmon
  • Quantity: 8.75oz., 17oz., and 33oz.

If you are looking for high-quality fish oil for your pet, you’ll be hard-pressed to find a brand with more options than Iceland Pure. Still, from all the available Iceland Pure Pet Products, their unscented salmon oil is our top pick for several reasons.

Firstly, it’s made exclusively from pharmaceutical-grade, Norwegian salmon.

The oil is molecularly-distilled, i.e., it’s extracted at low temperatures to ensure that the fatty acids preserve their nutritional value and that all harmful materials, such as toxins, heavy metals, and preservatives, are removed.

The brand goes one step further to preserve freshness and purity. Iceland Pure salmon oil for dogs is stored in an aluminum bottle with a micro-thin epoxy coating to avoid contamination.

This material doesn’t degrade, allowing the oil to stay fresh and last longer. The bottle comes with an easy-to-use pump, too.

What’s more, it’s ultra-filtered to remove the fishy odor, meaning you won’t smell this oil in your kitchen or on your dog’s breath. The natural, pet-enticing flavor remains, though, so owners can use it on its own or mix it in with their pets’ food.

Doggies are guaranteed to love it either way, as confirmed by more than just one Iceland Pure fish oil review.

This product has numerous health benefits, as well. Salmon oil—especially one of such superior quality—can help reduce inflammation, soothe irritated skin, and improve mobility.

Finally, thanks to the high EPA and DHA content (644mg and 476mg, respectively), this oil can help remove specific proteins and thus improve kidney function and reduce inflammation and glomerular hypertension (the glomeruli are the small blood vessels in the kidneys).

For that reason, fish supplements high in pure omega-3 acids—like Iceland Pure fish oil for dogs—are recommended as some of the most important nutrients in the dietary management of chronic kidney disease.

Active ingredients: Salmon oil, mixed tocopherols

Other Iceland Pure Products for Canines

The company’s Premier Omega Oil is one of the best fish oil products for large dogs. It’s specially crafted for bigger dogs and contains 3,000mg of omega-3 fatty acids, three times more than other fish oils.

Next in line, we have Sardine Anchovy Oil Pharmaceutical Grade & Unscented made from wild-caught small fatty fish. This oil has much of the same effects as the Iceland Pure unscented salmon oil pharmaceutical-grade product and can be a great alternative if your dog gets tired of the taste of salmon.

You can also surprise your pet with the shark liver oil offered by the company. Although Iceland Pure can’t legally make any claims, they suggest that shark liver oil can help fight cancer and offer relief for some of the cancer treatment side-effects, making this one of the best fish oil products for dogs with cancer.

Finally, you may opt for the Next Level Premier Infused CBD Fish Oil. It uses CBD’s anti-anxiety properties, the cancer-fighting effect of shark liver oil, and the combined anti-inflammatory powers of CBD and fish oil for a relaxed, healthy, and happy pet.


  • + Available in four bottle sizes
  • + Third-party tested
  • + Sold in an eco-friendly bottle
  • + High in essential fatty acids
  • + Amazing customer service
  • + 8.75oz bottle can be refunded even if slightly used

Nutri-Vet Wild Alaskan Salmon

star 9.6

Top Product for Overall Wellness

  • Origin: Globally sourced, US-made
  • Flavor: Salmon
  • Quantity: 6.5oz. and 16.5oz.

This vet-formulated dietary supplement is the perfect choice to meet your canine’s daily omega-3 requirements. Moreover, it’s made from wild, non-farmed Alaskan salmon.

This Nutri-Vet fish oil for dogs contains ample amounts of EPA and DHA to improve coat and skin, as well as immunity and mobility. The high omega-3 count can do wonders for your dog’s heart and brain, too.

Like all other Nutri-Vet products, this one is made following the strictest standards in pet nutrition. It delivers consistent quality with every batch and is 100% safe (free of artificial preservatives, heavy metals, or contaminants).

These features make the Nutri-Vet Wild Alaskan Salmon Oil dog supplement one of the best and most effective for overall health and wellness. User accounts confirm this as well.

Owners say that the product works, adding that dogs are hooked on the mouth-watering salmon taste. Actually, most of the negative Nutri-Vet fish oil reviews refer to the packaging—the leaky pump in particular, which can make administering a bit tricky.

Active ingredients: Salmon oil, mixed tocopherols, rosemary extract

Other Products From Nutri-Vet

You can also try the Nutri-Vet Fish Oil Softgels for Dogs. These contain an individually crafted blend of fish oil and antioxidants to reduce shedding and promote healthy skin and coat. In short, they offer the same benefits as the salmon oil but are easier to administer.

This is an excellent choice for senior dogs, as these chews can easily become a part of your doggie’s daily diet.

Lastly, we have the Nutri-Vet Omega Krill & Fish Oil for Dogs, which combines two sources of omega-3 (krill and fish) for the perfect solution to dry and itchy skin. Like the Nutri-Vet Salmon Oil in our review, this product is made from wild-caught fish to ensure optimal freshness, effectiveness, and purity.

Methodology for Choosing the Top Products for Pets

With so much choice on the market, finding the best fish oil supplements for your four-legged companion can be a bit overwhelming.

Don’t worry because we’re here to help!

Using a strict set of criteria, we combed through dozens of products and narrowed the list down not to one best fish oil supplement for dogs, but a variety of the best options out there.

Here’s a closer look at the methodology we used:


Does the product contain enough omega-3 fatty acids to be effective?

This is a tricky issue since the dosage depends on the dog’s breed, age, health, and what you’re using the product for.

To make things easier, we listed only the fish oil products for dogs that meet the technical recommendation and requirements. We included the amount of fish oil, EPA, and DHA each product contains to help you out even more. This makes it easier to determine which product is best suited for your dog.


The second-biggest concern pet parents have is the safety of supplements.

All brands can say that they make the best fish oil product for dogs. However, a reputable company should be able to back up their claims of safety and purity by prominently displaying CoAs on their site or providing them upon request.

That’s why we ranked brands that have their products rigorously tested by independent labs for any contaminants, heavy metals, toxins, or other harmful materials.

Source and Quality

The sourcing and manufacturing processes behind the best fish oil for dogs and cats determine the safety of the supplements and their quality and effectiveness. That’s why we asked the following questions regarding sources and quality:

  • What is the source of the fatty acids? What kind of fish is used? Does it contain high levels of omega-3s?
  • Is it sustainably sourced? Does the company use wild-caught fish or fish farms?
  • Where are the supplements made? Does the brand provide info on its manufacturing facilities? Are the supplements made in the US?

More Than Fish Oil

Less is not always more.

Fish oil has benefits for dogs, but sometimes other ingredients can be combined to complement the effects of omega fatty acids. For that reason, we listed brands that incorporate other beneficial components, such as hemp (for a calming effect) and glucosamine (for healthier joints).

We didn’t forget about the taste of the supplements either. In our rankings of the best fish oil food and supplements for dogs, we included products with a multitude of tastes dogs love.


The price tag is another important factor.

When completing our ranking of the best omega-3 fish oil for dogs, we made sure to select products that offered the best bang for your buck. In other words, brands that provided quantity and quality at reasonable prices.

User Reviews

No listing would be complete without the opinions and experiences of satisfied (and unsatisfied) users.

This is why we checked the fish oil for dogs reviews by pet parents across various platforms and brought you the ones with the highest ratings and the greatest number of positive comments.

Buying Guide to Choose the Perfect Supplement

Before you start shopping for fish supplements for canines, make sure to check out this insightful guide to learn more about what fish oil is and how it can benefit your doggo.

What Is Fish Oil for Dogs?

Fish oil, as the name suggests, is a type of fat derived from fish. This is so-called good fat that contains two essential fatty acids: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).

These omega-3 acids are called essential for a reason.

The best omega-3 for dogs helps regulate blood flow, reduce inflammation, and improve cognition, mobility, vision, and cardiovascular health. They promote healthy skin and coat too.

They also serve to balance out the omega-6 acids.

Omega-6s are very common in processed dog food and grains, and even though they are essential, an overabundance of omega-6s could prompt inflammation rather than reduce it.

Your dog needs a balanced diet to thrive, and omega-3s provide that.

Why and How to Include the Perfect Supplements for Canines in Your Diet?

Like humans, canines can’t produce omega-3 acids on their own, so they must get them through their food.

There are three ways to include omega-3 acids in your dog’s diet:

  1. Give your dog prescription food that is rich in fish oil.
  2. Include whole fish in your dog’s diet.
  3. Supplement your dog’s diet with fish oil.

The last option is the best because it’s:

  • The most accurate in terms of dosing.
  • The most efficient, as fish oil supplements can be more potent than a whole-fish diet.
  • The safest, because the best fish oil product for dogs doesn’t contain harmful chemicals.

Where Do Omega-3s Come From?

The primary sources of omega-3 acids are cold-water fish, such as mackerel, anchovies, salmon, herring, sardines, and sablefish (black cod).

EPA and DHA are actually produced by smaller marine life such as algae and phytoplankton, which are eaten by bigger fish and stored until they become part of the bigger organism. Thus, fish that eat these tiny creatures have higher levels of omega-3 acids.

Predators like sharks, tuna, swordfish, and tilefish also have high levels of EPA and DHA. However, they might contain other harmful materials that are not safe for consumption, such as mercury, toxins, and chlordane.

How does it benefit canines?

Fish oil supplements can:

  • Reduce inflammation—Fish oil can help treat dogs with arthritis, hip dysplasia, muscle spasms, and other inflammatory conditions of the joints.
  • Improve coat and reduce shedding—Taking fish oil supplements for a few months can give your pets a complete makeover. Their coat will be shinier, silkier, and the shedding will be reduced significantly, especially if it’s caused by allergies.
  • Calm down itchy skin—In addition to promoting a healthy coat and skin, the best fish oil for dogs’ skin can reduce some of the negative consequences of allergies and food intolerances, such as dry skin and irritation and dandruff.
  • Offer pain relief—Thanks to its anti-inflammatory effects, fish oil can provide relief from sore joints and muscle stiffness, allowing your four-legged friend to run and play without any discomfort.
  • Support brain and vision development—Good fish oil for dogs is proven to boost cognitive development and improve the vision of doggies of all ages, but most of all, puppies.
  • Kidney diseases—Fish oil is recommended as a treatment for the glomerular disease, a kidney condition in dogs associated with protein loss in urine, contributing to (or worsening) chronic kidney disease. Omegas in the best fish oil products for dogs can also slow down kidney damage.
  • Could slow down tumor growth—There’s some evidence to suggest that omega-3 fatty acids could reduce tumor growth, but more research is needed before establishing a definite link between cancer and omega-3 acids.

What Types of Canines Benefit From the Top Quality Products?

Fish oil is an excellent supplement for all dogs, but the following categories of canines need it more than others:

  • Senior dogs—As dogs get older, they start experiencing mobility and cognitive issues, high blood pressure, and obesity. Fish oil can relieve some of the pain related to stiff joints and help senior doggies suffering from canine cognitive dysfunction. Stick to liquids or use only the best fish oil omega-3 chewables for dogs you can find.
  • Pregnant dams—Omega-3s are an essential part of a pregnant dog’s diet. They help fetal development and boost immunity, making sure that pregnant (or lactating females) are in top health condition during this exciting time. Fish oil can regulate blood pressure, too, contributing to a safer pregnancy and birth.
  • Puppies—DHA and omegas are a common component of puppy food because of the benefits these fatty acids give to a puppy’s development and growth (brain, bone, and vision).
  • Large breed dogs—The bigger the dog, the more prone it is to joint issues. Fish oil can reduce inflammation, allowing bigger dogs to move freely and thus improving their quality of life.

How Much Supplement Should You Give a Canine?

If you want to be on the safe side when it comes to fish oil for dogs, the dosage that is usually recommended is around 75–100 mg/kg.

If you don’t want the hassle of converting your dog’s weight to kilograms, there are easier ways to determine the correct dosage. One involves multiplying your canine’s weight by 20. This will give you an estimation of how much fish oil you should give your dog.

Let’s say your pooch weighs 15 lbs. Then the EPA (or DHA) dose will be 300 mg. A supplement containing 1000 mg fish oil for dogs would be the best dosage for a 50 lb. canine, such as a Bulldog or Spaniel.

An even easier way to get the dosage right is to use a fish oil dosage calculator for dogs, which is basically a dosing chart showing the recommended amount of fish oil your pooch needs.

It doesn’t matter if you have a small or a large dog, a fish oil overdose is uncommon, but it’s still very important to get the dosage right.

Supplement for Canines and its Side Effects

As with any supplement, fish oil also has inevitable side-effects. Luckily, the adverse effects are rare and not very serious.

These are some of the most common side effects of fish oil in dogs:

  • Dogs might not be able to digest fish oil, leading to gastrointestinal issues. Although these issues aren’t that serious and are resolved without intervention over time, they still cause discomfort.
  • Some omega-3 fatty acids can cause blood clots, usually when combined with other blood-thinning medications.
  • Because they have anti-inflammatory effects, it’s not advisable to combine fish oil tablets for dogs with other anti-inflammatory drugs without a previous discussion with a professional.
  • Fish oil might give your doggie bad breath. This is more of an inconvenience to you than your dog. The good news is that you can just reduce the amount of oil in his diet and not be troubled by fishy breath anymore.

Even though these side effects aren’t severe, it’s good to discuss any possible adverse effects and benefits with your vet. Your vet must know your dog is taking omega-3 supplements before any medical procedure is carried out (due to medication interaction).

Which Is the Top Supplement for Canines, and How to Find It?

Here are a few helpful tips on choosing high-quality fish oil:

  • Go for supplements derived from wild-caught fish, as dog food from fish farms might contain heavy metals and toxins.
  • Consider bio-availability—There are three kinds of fish oil: natural triglyceride (the easiest to absorb and possibly the best type of fish oil for dogs), ethyl ester oil (distilled with high levels of EPA and DHA), and synthetic triglyceride oil (artificial and the least bioavailable of the three).
  • Check if it’s made in a country with strict quality-control standards—This includes the US, Canada, Australia, and Western Europe, where products are made under rigorous health and safety standards.
  • The best kind of fish oil for dogs should have a Certificate of Analysis (CoA).
  • Look at the ingredients, i.e., check the EPA and DHA levels in the fish oil to make sure that the dosage is right for your dog. Look at the calorie count, too.

Decide how you want to administer it—fish oil is available in oil-form, chews, and capsules. It doesn’t matter whether you choose top-notch fish oil, soft chews, or any of the best fish oil supplements for dogs, as all are easy to administer, equally effective, and taste great.
