This post contains affiliate links. As an Amazon Associate, we earn from qualifying purchases.
The Nordic Naturals Omega-3 Pet Fish Oil takes our Best Overall spot thanks to its 1380 mg omega-3 per teaspoon in the highly absorbable triglyceride form, backed by wild-caught, non-GMO sourcing. For owners who prefer a pre-portioned chew, the Nutramax Welactin Omega-3 Soft Chews earned our Best Vet-Recommended Chews award, while the Nordic Naturals Omega-3 Fish Oil Softgels won Best Softgel Supplement for mess-free precision.
Most dog owners know omega-3s support a shiny coat and healthy joints, but the real challenge is picking the right form, dose, and source among dozens of oils, chews, and softgels. A liquid might offer a higher dose per serving but requires measuring, while a soft chew is convenient but often contains a lower omega-3 count. This guide cuts through the noise.
We built this guide by examining manufacturer specifications, ingredient sourcing, and patterns in owner feedback across the top-rated products. Our goal is to give you a clear, research-based framework for choosing the right supplement for your dog’s size, taste preferences, and health needs.

The Best Omega 3 Supplements For Dogs, Reviewed
Nordic Naturals Omega-3 Pet Fish Oil
What We Like
- 1380 mg omega-3 per teaspoon
- Triglyceride form for optimal absorption
- Wild-caught, non-GMO, gluten-free ingredients
- Ethical and sustainable sourcing
Trade-offs
- Liquid form requires measuring each dose
- Not suitable for owners who prefer chews or softgels
A single teaspoon delivers 1380 mg of omega-3s in the triglyceride molecular form naturally found in fish, which supports optimal absorption. The oil is sourced from wild-caught fish and contains no GMOs, gluten, dairy, or artificial colors, flavors, or preservatives. This makes it a straightforward liquid supplement for owners who prioritize sourcing and purity.
It’s a liquid, not a chew or softgel. You’ll need to measure each serving and mix it into food. If your dog is a finicky eater or you’d rather not deal with a bottle and a dropper, the Nordic Naturals Omega-3 Fish Oil Softgels offer the same brand quality in a capsule form, though at a lower omega-3 count per serving (320 mg per serving). For owners who want a high-dose liquid with clean ingredients, this version fits the bill.
Nutramax Welactin Omega-3 Soft Chews
What We Like
- Soft chews for easy daily dosing
- Includes beta-glucan for immune support
- Contains EPA and DHA from fish oil
Trade-offs
- Contains added vitamins and minerals some dogs don't need
- Soft chews have a strong fishy odor some dogs refuse
Nutramax has been a leader in pet health for over 25 years, and their Welactin soft chews are a rich source of EPA and DHA from fish oil, plus beta-glucan to support immune function. That means you get skin and coat benefits along with broader health support in one daily chew. The company runs thorough quality inspections, so you can feel confident giving this to your dog every day.
Choosing between a liquid and a soft chew comes down to how your dog handles supplements. Soft chews are convenient for most dogs, but if yours spits out pill pockets or turns up a nose at anything that smells like a treat, you will have a harder time getting the dose in. Compare that to the liquid oil from Nordic Naturals, which comes in a 16 oz bottle and delivers 1380 mg of omega-3s per teaspoon, offering a different administration method.
Nordic Naturals Omega-3 Fish Oil Softgels
What We Like
- Triglyceride form for optimal absorption
- Wild-caught, sustainably sourced fish oil
- Free of artificial colors, flavors, preservatives
- Formulated specifically for dogs
Trade-offs
- Only 320 mg omega-3 per serving
- Not suitable for cats, use only pet-specific products
The 320 mg of omega-3 per serving in triglyceride molecular form means your dog gets the same naturally structured fatty acids found in fresh fish, which research shows absorb better than synthetic forms. That makes these softgels a smart choice for owners who want a precise, mess-free dose without the sticky bottle or fishy fridge smell that comes with liquid oils. They are especially suited for dogs who need consistent heart, skin, coat, and immune support without the guesswork of measuring teaspoons.
The trade-off is the softgel itself: if your dog is a picky chewer or very small, you might end up cutting or poking each capsule to squeeze the oil onto food, which defeats the convenience. Compared to the liquid Nordic Naturals Omega-3 Pet Fish Oil that delivers 1380 mg per teaspoon, these softgels are better for portion control but offer less total omega-3 per serving. For medium to large dogs who swallow pills easily, this is a clean, reliable way to supplement.
Grizzly Wild Alaskan Salmon Oil
What We Like
- Certified wild caught Alaskan salmon
- Medical grade air-tight pump
- Balanced EPA and DHA blend
- Supports whole body health
Trade-offs
- Only one size offered in this line
- Pump can be difficult for arthritic hands to press
Grizzly Wild Alaskan Salmon Oil delivers a balanced blend of EPA and DHA from certified wild caught salmon, with every batch verified by third-party labs. The medical-grade pump provides exact measurement for dosing. For owners who want a liquid supplement with verified sourcing and quality control, this is a straightforward option.
The pump bottle delivers an exact measurement with a medical-grade pump, so you don’t have to guess how much omega‑3 your dog is getting. That precision means every meal gets a consistent dose of EPA and DHA, which helps support the immune system, heart, organ health, cognition, vision, fertility, nerve function, and a healthy skin and coat. Owners who want to adjust the amount per serving will appreciate the control the pump gives them, though the liquid form does require a steady hand to avoid spills.
Wuffes Omega-3 Fish Oil for Dogs
What We Like
- 100% pure wild Alaskan pollock oil
- No added fillers or artificial ingredients
- Supports skin, coat, joint, and heart health
- Sustainably sourced and scientifically backed
Trade-offs
- Only one flavor option: pollock.
- Not suitable for dogs allergic to pollock.
Wild Alaskan pollock oil is the single ingredient here, with no fillers or additives to dilute the EPA and DHA your dog gets. That means each serving delivers straight omega-3s for skin, coat, joints, and general health, without you having to guess what else is in the bottle. If you want a clean, single-source oil and value sustainability as much as ingredients, this is a straightforward pick that doesn’t try to be anything else.
An 8-ounce bottle of this pollock oil is smaller than the 16-ounce Grizzly Wild Alaskan Salmon Oil, so if you have a larger dog or multiple pups, you may need to buy more frequently. But the oil is 100% pure Wild Alaskan Pollock Oil, made in the USA from sustainably caught Pollock, with no added fillers or nasties.
Zesty Paws Salmon Oil for Dogs & Cats
What We Like
- Easy-to-mix liquid pump formula
- Blend of salmon and pollock oils
- Supports skin, coat, joints, and immune system
- Gentle for skin and coat nourishment
Trade-offs
- Pump dispenser can clog without regular cleaning
This supplement combines salmon oil and pollock oil, giving your pet omega-3s from two marine sources instead of just one. The liquid pump design makes it simple to add to food, no capsules or chews to wrestle with. The EPA and DHA content supports skin, coat, joints, heart function, and immune health all at once, covering multiple bases in a single product.

Native Pet Omega 3 Fish Oil for Dogs
What We Like
- Leak-proof locking pump dispenser
- Two wild-caught fish for broader omega profile
- Zero fillers, non-GMO ingredients
- Vet-developed formula
Trade-offs
- Daily pumping for multi-dog households
- Liquid requires a moment of attention at each meal
The pump dispenser with a locking mechanism means you can portion out omega-3s one-handed, no sticky drips or guessing how much came out. Two pumps per twenty pounds of body weight is straightforward enough that you don’t need a measuring spoon or a second cup of coffee to get it right. That matters when you’re adding a supplement to every meal and want the routine to stay simple. The blend of wild-caught Alaskan salmon oil and pollock oil gives a wider fatty-acid profile than a single-fish source. The NASC Quality Seal means the manufacturer submits to third-party audits for ingredient purity and label accuracy. For anyone who values convenience without wanting to chase a greasy bottle around the kitchen counter, this is the most practical liquid option in the guide.
The pump bottle delivers two precise pumps per 20 pounds of body weight, so there is no guesswork at mealtime. Compared to the pour-top bottles used by other brands, the locking mechanism keeps the bottle clean and leak-proof in the fridge. For owners with one dog and a consistent routine, this design eliminates the mess of over-pouring or wiping oil off the bottle exterior. Travelers or multi-dog households might prefer a different format, but for daily use at home the pump is a clear win.

Natural Dog Company Wild Alaskan Salmon Oil
What We Like
- Wild-caught Alaskan salmon and pollock oil
- Pump dispenser for easy dosing
- Supports skin, coat, joints, heart, immune
- Verified by Orivo for species and origin
Trade-offs
- Pump dosing requires remembering correct number of pumps per weight
- Not suitable for dogs that refuse fish-flavored toppers
A 16-ounce bottle of wild-caught Alaskan salmon and pollock oil gives you a straightforward way to add omega-3s to a dog’s bowl, with a pump that meters out the right amount by weight. The blend of two fish oils delivers EPA and DHA for skin moisture, coat shine, joint mobility, and immune support. That makes it a practical daily topper for dogs who scratch through seasonal changes or need a little extra help with shedding. The pump dispenses directly onto meals, so you avoid measuring spoons and messy bottles.
The pump requires you to remember the right number of pumps for your dog’s weight and to introduce the oil gradually to avoid digestive upset. For owners who prefer pre-portioned supplements, soft chews offer a different convenience. But if you want a flexible, pumpable topper that targets itch relief and coat quality, this oil does the job without fillers or artificial additives.

BARK&SPARK Omega 3 Fish Oil Treats
What We Like
- 500 mg omega per chewable treat
- 180-count jar lasts up to 3 months
- Human grade ingredients made in USA
- Natural flavors for picky eaters
Trade-offs
- Only 500 mg omega per serving, lower dose than some oils
- Not suitable for dogs that refuse soft chews
Each serving provides 500 mg of EPA and DHA, so you get meaningful omega-3 support for skin, coat, and joint health in a form your dog actually wants to eat. The 180-count jar stretches to a three-month supply, which makes it a practical choice for owners who want consistent daily dosing without wrestling with a dropper or syringe. Picky eaters are a non-issue here, the natural salmon flavor does the convincing for you.
Each serving delivers a lower omega dose than a liquid oil like Nordic Naturals Omega-3 Pet, which gives 1380 mg per teaspoon. If your large breed needs a higher daily dose, you will need multiple servings. For most owners looking to stop itching and shedding without a fuss, this is a straightforward option in the guide.

PlanoPaws Wild Caught Omega 3 Fish Oil
What We Like
- Low-odor formula for picky dogs
- Molecularly distilled to remove toxins
- Human-grade quality from Icelandic waters
- Pump bottle makes dosing easy
Trade-offs
- Not suitable for dogs that refuse liquid supplements
A 32-ounce pump bottle of human-grade fish oil from wild-caught Icelandic anchovies, herring, mackerel, and sardines means you’re getting a concentrated dose of EPA and DHA without the fishy smell that sends dogs running. The molecular distillation strips out heavy metals and toxins, so you’re not trading one health problem for another. This is the liquid to grab if your dog turns up their nose at standard fish oils or you’re tired of your kitchen smelling like a cannery.
Liquid oils demand a bit more care than soft chews or capsules. Compared to Nordic Naturals’ soft gels, which are pre-portioned, the PlanoPaws requires a little more daily effort. But for owners whose dogs refuse anything with a strong odor, that extra step is worth skipping the wrestling match at mealtime.

How We Evaluated Omega 3 Supplements For Dogs
Our evaluation started with a deep dive into each product’s stated omega-3 content per serving, the molecular form (triglyceride versus ethyl ester), and the source of the oil. We cross-referenced these specs with manufacturer documentation on sourcing, purity testing, and ingredient transparency. We also looked at patterns in owner feedback to understand real-world palatability and ease of use.
The three criteria that mattered most were omega-3 potency per dose, the form of the supplement (liquid, softgel, or chew), and the quality of sourcing. Potency determines how many pumps or chews you need per day. The form affects whether your dog will actually take it. Sourcing, wild-caught versus farmed, single-source versus blended, determines the fatty acid profile and overall purity.
A research-led evaluation has limits: we did not lab-test these products ourselves, and individual dog preferences vary widely. What works for a Labrador that gulps anything may not work for a picky Pomeranian. That is why we emphasize form and palatability alongside potency in our rankings.
What To Look For In Omega 3 Supplements For Dogs
Choosing the right omega-3 supplement means balancing your dog’s taste preferences, your dosing convenience, and the quality of the oil itself. Here are the key factors to weigh.
Focus on the omega-3 dose per serving, the molecular form (triglyceride absorbs best), and whether your dog will actually eat the delivery method you pick.
Omega-3 Potency And Molecular Form
The total omega-3 content per serving, measured in milligrams of EPA and DHA combined, determines how much you need to give. A high-potency liquid like the Nordic Naturals Omega-3 Pet Fish Oil delivers 1380 mg per teaspoon, which is enough for large breeds in a single serving.
Lower-potency options like the BARK&SPARK Omega 3 Fish Oil Treats provide 500 mg per chew, requiring multiple treats per day for bigger dogs. The molecular form matters, too: triglyceride-form omega-3s are absorbed more efficiently than ethyl ester forms, so you get more benefit from each milligram.
Delivery Form: Liquid, Softgel, Or Chew
Liquids offer the highest dose per serving and are easy to mix into food, but they require measuring and can be messy. The liquid fish oil category includes pump bottles like the Grizzly Wild Alaskan Salmon Oil and the Native Pet Omega 3 Fish Oil for Dogs, which simplify dosing.
Softgels give you a precise, no-mess dose but require your dog to swallow a pill. That is easier for large breeds than small ones. Chews like the Nutramax Welactin Omega-3 Soft Chews are the most convenient for picky dogs, but they often contain added vitamins and a lower omega-3 count. Check the label to ensure the dose matches your dog’s needs.
Sourcing And Purity
Wild-caught, single-source fish oils from Alaska or Iceland generally have a cleaner fatty acid profile and fewer contaminants than farmed or blended oils. The Natural Dog Company Wild Alaskan Salmon Oil is verified by Orivo for species and origin, while the PlanoPaws Wild Caught Omega 3 Fish Oil is molecularly distilled to remove toxins.
If your dog has a known fish allergy, a single-source oil like the Wuffes Omega-3 Fish Oil for Dogs (100% pollock) lets you avoid the trigger. For owners exploring alternatives, krill oil offers a different fatty acid profile that some dogs tolerate better.
- Confirm the omega-3 dose per serving matches your dog’s weight, small breeds need less, large breeds need more.
- Choose a form your dog will reliably eat: liquid for mixers, softgels for gulpers, chews for treat-motivated dogs.
- Check for third-party purity testing or molecular distillation, especially for liquid oils.
- Look for a pump dispenser on liquids to reduce mess and oxidation from repeated bottle opening.
- Avoid supplements with long lists of added vitamins or fillers unless your dog specifically needs them.
A simple rule: the best omega-3 supplement is the one your dog will actually take every day at the correct dose.

Frequently Asked Questions
How much omega-3 does my dog need each day?
The general guideline is about 100 mg of combined EPA and DHA per 10 pounds of body weight for maintenance, and up to double that for dogs with joint or skin issues. Check the label for the per-serving omega-3 content and adjust the number of pumps, softgels, or chews to hit that target. Always consult your veterinarian for a dose tailored to your dog’s specific health conditions.
What is the difference between triglyceride and ethyl ester omega-3s?
Triglyceride form is the natural molecular structure found in fish, and it is absorbed by the body more efficiently than ethyl ester form, which is a synthetic, concentrated version. Supplements that specify “triglyceride form” on the label, like the Nordic Naturals line, deliver more usable omega-3 per milligram. Ethyl ester oils are still effective but may require a slightly higher dose for the same benefit.
Can I give my dog human omega-3 supplements?
It is safer to use a supplement formulated specifically for dogs, because human products may contain different dosages, added ingredients like xylitol, or higher concentrations of vitamins that can be harmful to pets. The Nordic Naturals Omega-3 Fish Oil Softgels, for example, are formulated specifically for dogs. Stick to pet-labeled products unless your veterinarian directs otherwise.
Will omega-3 supplements help my dog’s itchy skin?
Many owners report improvements in skin and coat condition after adding omega-3s, particularly from salmon oil or pollock oil sources. The Natural Dog Company Wild Alaskan Salmon Oil and the BARK&SPARK Omega 3 Fish Oil Treats are both popular choices for supporting skin allergies. For persistent itching, a veterinary evaluation is important to rule out underlying allergies or infections.
How long does it take to see results from omega-3 supplements?
Most owners notice improvements in coat shine and reduced shedding within weeks of consistent daily dosing. For joint health and mobility benefits, it can take weeks to months before changes are noticeable. Consistency matters more than a high initial dose, so pick a form you can stick with daily.
The Bottom Line
For most dog owners, the Nordic Naturals Omega-3 Pet Fish Oil is the best overall choice because it delivers a high dose of triglyceride-form omega-3s from wild-caught, sustainably sourced fish in a single teaspoon serving. It works well for medium to large dogs that don’t mind a fishy flavor mixed into their food.
If your dog refuses liquids or you prefer the convenience of a pre-portioned chew, the Nutramax Welactin Omega-3 Soft Chews offer the added benefit of beta-glucan for immune support. For owners who want a precise, no-mess softgel, the Nordic Naturals Omega-3 Fish Oil Softgels provide the same high-quality sourcing in a pill form.
The single most important factor is finding a supplement your dog will actually eat every day at the correct dose. Start with the form that fits your routine, then check the omega-3 content per serving against your dog’s weight. A supplement you can stick with beats a perfect formula that sits untouched in the cupboard.
