Best Fish Oil for Dogs? Why Ranking Lists Don’t Tell the Whole Story

If you have ever searched for the “best fish oil for dogs”, you have probably seen big-name articles ranking different brands.

They can look helpful. They often include vet comments, product comparisons, prices and convenient buying links.

But here is the question pet owners should be asking:

Is this truly the best fish oil for my dog — or simply the best fish oil available through that retailer?

Many online “best of” lists are commerce articles. That does not automatically make them wrong, but it does mean pet owners need to look deeper before choosing a fish oil for their dog or cat.

Because with fish oil, the brand name is only one part of the story.

The real questions are:

Where did the fish come from?
What species was used?
How fresh is the oil?
How was it handled?
Is the EPA and DHA clearly stated?
Has the oil been tested?
How is it protected from heat, light and oxidation?

Those questions matter far more than a ranking badge.

Why I Look at Fish Oil Differently

I have been working with animals for most of my life — as a pet owner, breeder, vet nurse, and founder of Newflands.

I did not choose hoki oil because it was trendy.

I chose it because I was looking for something better for my own dogs. Something clean, practical, and gentle enough to use every day.

Over the years, I have seen how much difference small daily support can make to a pet’s coat, skin, movement, comfort and overall wellbeing.

That does not mean fish oil is magic. It is not.

But I do believe pet owners deserve to know what they are putting into their animals’ bodies. They deserve more than a pretty label, a ranking badge, or a “best of” list that only shows products available through one retailer.

When I look at a fish oil, I want to know:

What fish did it come from?
Where was it sourced?
How fresh is it?
How has it been handled?
Has it been tested?
Can the company explain why they chose that oil?

That is the kind of thinking behind Newflands Hoki Oil.

It comes from years of living with animals, learning from them, caring for them, and wanting better options for owners who are trying to do the right thing.

Why “Best Fish Oil” Lists Can Be Misleading

A “best fish oil for dogs” article may still contain useful information.

The problem is that many of these articles are also designed to help people buy products through shopping links. That means the products included may be limited to what is available through certain retailers or affiliate programmes.

That does not make the products bad.

But it does mean pet owners should pause before assuming the product at the top of the list is automatically the best choice for their own dog.

The better question is:

Best based on what?

Best price?
Best-known brand?
Best affiliate link?
Best product available through one online retailer?
Best source?
Best freshness?
Best transparency?

Those are very different things.

What Pet Owners Should Check Before Buying Fish Oil

Before choosing any fish oil for your dog or cat, here are the questions I believe matter most.

1. What Fish Species Is the Oil From?

Not all fish oils are the same.

Some come from salmon. Some come from anchovy, sardine or mixed fish sources. Some come from unnamed “marine oil” blends.

At Newflands, we use New Zealand hoki oil.

Hoki is not as famous as salmon, but that is part of what makes it interesting. It is a beautiful New Zealand marine species with a strong sustainability story and naturally occurring omega-3 fatty acids.

When a company tells you exactly what species the oil comes from, that is a good sign.

When the label simply says “fish oil” without a clear species or source story, I would be asking more questions.

2. Is the EPA and DHA Clearly Listed?

EPA and DHA are the key omega-3 fatty acids pet owners are usually looking for in fish oil.

Do not judge a product only by the total amount of fish oil in the bottle.

A label might say “1000 mg fish oil”, but that does not always tell you how much EPA and DHA your pet is actually getting.

Look for clear information about EPA and DHA levels.

That matters far more than a big number on the front of the label.

3. Has the Oil Been Tested?

Fish oil should be tested.

Pet owners should be able to ask about purity, heavy metals, contaminants and freshness.

This matters because fish oil is a natural marine product. Good companies should not be afraid of testing. They should welcome it.

At Newflands, testing and transparency are part of the trust story behind our products.

4. How Is the Oil Protected From Heat, Light and Oxidation?

Fish oil is sensitive.

Heat, light, air and time can all affect oil quality. Once oils oxidise, they may smell stronger, taste unpleasant, and lose some of the freshness pet owners are trying to provide.

This is why packaging, storage and handling matter.

A good fish oil is not just about what fish it came from.

It is also about how carefully it was handled from source to bottle.

5. Is the Source Sustainable?

This is a big one.

If we are using marine resources to support pet health, we also need to care about where those resources come from.

New Zealand hoki has an important sustainability story. The New Zealand hoki fishery was the first large-scale whitefish fishery to achieve Marine Stewardship Council certification in 2001.

That matters to me because Newflands has always been about using New Zealand’s natural resources respectfully, not wastefully.

6. Is the Company Transparent?

This may be the most important question of all.

Can the company explain why they chose that oil?

Can they tell you where it comes from?

Can they tell you how it is tested?

Can they tell you how to store it?

Can they explain the difference between their product and the cheaper options?

If the answer is no, keep looking.

Why New Zealand Hoki Oil Is Different

Newflands Hoki Oil was not created because I wanted to add another fish oil to the shelf.

It came from my own experience with animals and my belief that New Zealand hoki had an important story to tell.

Hoki gives pet owners another option beyond the usual salmon oil products.

For me, hoki oil has always been about more than omega-3 numbers.

It is about source, freshness, traceability, sustainability and trust.

It is also about using a New Zealand resource in a way that respects the fish, the ocean and the animals we are caring for.

Why Freshness Matters More Than Fancy Marketing

A fish oil can have beautiful branding and still be poorly handled.

A fish oil can have a big “best” badge and still leave you wondering where the oil actually came from.

Freshness matters because fish oil is delicate.

That is why pet owners should look beyond the front label and ask practical questions:

Does it smell fresh?
Is it stored correctly?
Is the bottle protected from light?
Does the company give clear storage guidance?
Can you find the EPA and DHA information?
Can you contact the company and get a real answer?

Those questions will tell you far more than a ranking article ever will.

My Note

Newflands began because I wanted better options for pets, including my own.

My background in animal care, vet nursing, breeding and education has shaped how I look at pet wellness. I do not believe pet owners need to be overwhelmed or frightened into buying products.

But I do believe they deserve honest information.

When I see “best fish oil” lists that do not tell the full story, I worry that pet owners are being trained to choose based on ranking, price or convenience rather than quality, source and trust.

That is why I keep talking about hoki oil.

Not because it is trendy.

Because I believe it deserves to be understood.

The Bottom Line: Do Not Just Ask “What Is Best?” Ask “Best Based on What?”

The best fish oil for your pet is not always the one at the top of a shopping list.

It is the one with a clear source, honest testing, careful handling, proper storage, and a company willing to explain exactly what is inside the bottle.

For Newflands, that starts with New Zealand hoki — a beautiful, sustainable marine source of omega-3, chosen because we care about what goes into our pets as much as we care about what goes into our own families.

Why Choose Newflands Hoki Oil?

Newflands Hoki Oil is made from New Zealand hoki, clearly sourced, naturally rich in omega-3 EPA and DHA, tested for quality, and chosen by a New Zealand animal-care Vet Nurse founder who wanted a clean, practical daily oil for her own pets. It is designed for dogs and cats and can be added easily to their food each day to support skin, coat, mobility and general wellbeing.

Frequently Asked Questions About Fish Oil for Dogs

What is the best fish oil for dogs?

The best fish oil for dogs is not just the one with the biggest brand name or the highest ranking online. Look for a fish oil with a clear fish species, known source, listed EPA and DHA levels, careful storage guidance, and testing for quality and purity.

Is hoki oil good for dogs?

Hoki oil can be a useful omega-3 source for dogs because it naturally contains EPA and DHA. Newflands Hoki Oil is made from New Zealand hoki and is used to support skin, coat, mobility, comfort and general wellbeing.

Is hoki oil different from salmon oil?

Yes. Hoki oil and salmon oil come from different fish species. Hoki is a New Zealand whitefish with its own sustainability and omega-3 story. Salmon oil is more widely known, but pet owners should still check source, freshness, handling and testing for any fish oil.

What should I check on a fish oil label?

Check the fish species, EPA and DHA levels, dosage instructions, storage instructions, batch or testing information, and whether the company explains where the oil comes from.

Can fish oil go off?

Yes. Fish oil can oxidise when exposed to heat, light, air or time. This is why storage, packaging and freshness matter. Always follow the storage instructions on the product label.
