Nordic Naturals Omega-3 Pet Review: Fish Oil for Dogs Worth Trying

Quick Verdict

The Nordic Naturals Omega-3 Pet is a genuinely well-made fish oil supplement for dogs built on the same quality standards as their human products. If you want a clean, triglyceride-form omega-3 with solid sourcing credentials, this is worth the investment. I'd rate it 4.5 out of 5 — the only real downsides are cost and the fact that you'll need to hide the soft gels in something tasty.

What Is the Nordic Naturals Omega-3 Pet?

Let's be honest — when I first heard about a premium human supplement brand making a pet version, my first thought was "marketing play." But Nordic Naturals Omega-3 Pet isn't just a rebranded human product. The company uses the same cold-water fish sourcing and manufacturing quality protocols, but adjusts the soft gel size and concentration for dogs and cats. Each soft gel delivers 320 mg of total omega-3s, including EPA and DHA, in the triglyceride molecular form — the form your dog's body actually absorbs best.

The product comes in an unflavoured soft gel format with 180 gels per bottle. No artificial colours, flavours or preservatives. Non-GMO, gluten-free and dairy-free. Nordic Naturals also emphasises its sustainable and ethical wild-caught fish sourcing, which is worth knowing if you're the type of pet owner who reads the back of the bottle twice.

Key Features

• 320 mg omega-3 per soft gel, including meaningful EPA and DHA levels
• Triglyceride molecular form for better absorption than cheaper ethyl ester oils
• Wild-caught, sustainably sourced fish with full traceability
• No artificial colours, flavours, preservatives or common allergens
• Non-GMO, gluten-free and dairy-free formula
• 180 soft gels per bottle — good value at standard dosing
• Same manufacturing quality standards as Nordic Naturals' human supplements

Hands-On Review

Three years ago I gave my previous dog a generic fish oil from a pet store shelf. She smelled like a fish processing plant for two days, wouldn't let me near her ears to check them, and I'm still not sure she absorbed much of it. When Nordic Naturals reached out — or rather, when I decided to finally test one properly — I approached it with the scepticism of someone who's been burned before.

My Labrador, Mochi, is a 62-pound senior who has developed that dry, flaky skin that comes with age. Within the first week of giving her one soft gel daily hidden inside a piece of cheese, I noticed zero fishy smell or aftertaste on her breath. That was the first pleasant surprise. By week four, the skin on her flanks — previously prone to visible flaking — had smoothed out noticeably.

What surprised me was the coat change. I expected the skin improvement because omega-3s are well-documented for supporting skin hydration. But the shine? That came faster than I anticipated. By week five, Mochi's coat had a glossiness that honestly made her look two years younger. I caught myself running my hand along her back just because it felt different.

The soft gels themselves are small enough to swallow whole if your dog is cooperative, but I found it easier to pierce them with a fork and squeeze the oil onto her kibble. The oil has a faint amber colour and a mild but not unpleasant fish scent — nothing like the overwhelming ocean smell I associate with cheaper fish oils. Refrigeration after opening kept them fresh throughout the two-month test period.

Will I keep using it? Honestly, yes — with one caveat. At roughly $30-35 per bottle and one gel daily for a medium-to-large dog, the cost is reasonable but not negligible. For small dogs the daily dose is lower, making it more economical. Skip this if you have a dog that absolutely refuses any supplementation — no amount of quality oil helps if it ends up on the floor.

Who Should Buy It?

Dog owners whose pets show signs of dry, flaky or itchy skin will likely see meaningful improvement within four to eight weeks. If your dog has a dull coat that lacks shine despite a balanced diet, the EPA and DHA in these soft gels can help restore lustre from the inside out. Senior dogs like Mochi seem to benefit particularly well, since ageing skin loses moisture and elasticity faster. Pet owners who value clean supplements — non-GMO, allergen-free, sustainably sourced — will appreciate the transparency in Nordic Naturals' sourcing and formulation.

Skip this if you have a small dog on a tight budget, since daily dosing over months adds up faster at smaller body weights. If your dog is already eating a high-quality food with significant fish content, you may not need additional omega-3 supplementation. And if your dog actively refuses any hidden supplements despite your best efforts, this format won't solve that behavioural challenge.

Alternatives Worth Considering

If you want a similar triglyceride-form omega-3 but at a lower price point, the VETRISCIENCE NuCat Plus soft chews include omega-3s alongside antioxidants in a format cats love — though the omega-3 concentration per serving is lower. For owners who prefer a liquid fish oil that can be mixed into food, Grizzly Salmon Oil offers a pump-dispensable format with no soft gels to manage, though the flavour can be stronger. If you need a veterinary-prescribed high-dose option for a dog with specific skin conditions, ask your vet about Welactin Omega-3, which offers a concentrated EPA/DHA ratio specifically formulated for dermatological use.

FAQ

Final Verdict

After two months with the Nordic Naturals Omega-3 Pet, I'm confident recommending it as a quality option for dog owners who want to supplement their pet's diet with clean, well-absorbed omega-3 fatty acids. The triglyceride form matters — it's the difference between what your dog swallows and what your dog actually uses. Combine that with wild-caught sourcing and the company's third-party purity testing, and you've got a supplement that earns its price tag. The main reasons to look elsewhere are cost over long-term use and administration practicality for finicky dogs. If those aren't dealbreakers for you, the Nordic Naturals Omega-3 Pet is a solid addition to your dog's wellness routine.
