The bottle sat in our refrigerator door for three weeks before I opened it. I had a yellow Lab and golden retriever mix named Biscuit, ten years old and 72 pounds, and X-rays in September 2024 had shown arthritis in both hips and stiffness in his left knee. Our vet, Dr. Amundsen, had read every label I brought her, and the one she kept pointing back to was Nordic Naturals Omega-3 Pet. I put it off, because I did not want to be a woman who bought five bottles and called it a cure.
What changed my mind was smaller than that. Biscuit had stopped getting up off the kitchen floor without a pause, and our walks had gone from about 40 minutes to about 15. I keep a paper practice log on the kitchen counter, the same kind I used to hand to students, one line a day: how he got up, how the stairs went, how far we walked. I started the Nordic Naturals liquid in January 2025, months after his Cosequin and months before anything else, so the log had a chance to say something. It is November 2026 now and the bottle is still in the door. Here is what I would tell you about it, in the order I would tell a friend.
The one bottle I did not quietly stop giving after two months
Nordic Naturals Omega-3 Pet is an unflavored liquid fish oil for dogs, eight ounces, poured over kibble at breakfast. It did not touch Biscuit's hips. It did change his coat, and it is the one Dr. Amundsen asked me to keep.

I want to be straight with you from the first item. I never saw Nordic Naturals do anything for Biscuit's hips. What I saw was his coat. He had been flaky along the back and dull all that first winter, and about eight weeks after he started the oil, my hand came away clean when I ruffled him. The listing names coat, eyes and heart. Coat is the one I can vouch for from my own kitchen.
A liquid goes over kibble without the tablet problem
Biscuit eats nearly anything out of a bowl, but in his first week of Cosequin he spat a tablet onto the floor when I handed it to him. Ever since, everything goes on top of the kibble. A liquid is the easiest version of that. The label's amount for his weight goes over his breakfast at seven in the morning, and by five he has forgotten it was ever there. No pill pocket. No peanut butter. No negotiation at the counter.
Unflavored means breakfast stays breakfast
It is unflavored, which matters more to Glen than to Biscuit. It smells like fish when you pour it, and Glen has opinions about that at seven in the morning. Biscuit has never once turned his nose up at it. I raise this because a supplement your dog refuses is a supplement you stop buying, and in 22 months this one has never caused a skipped meal.
It lives in the refrigerator door, so it stays part of the morning
The bottle goes in the refrigerator door after opening, never in the cupboard with the other four. I like that more than I expected to. Things that live in a cupboard get buried behind the turmeric. Things in the door get poured, because my hand is already there for the milk. It is a silly reason to trust a supplement. It is also the reason it actually gets given.
Eight ounces goes a long way at one pour a morning
The bottle is eight ounces, 237 milliliters, sized about like a small bottle of vanilla. At the label's amount for his weight, one bottle covers a good stretch of mornings, so you are not reordering every other week. That sounds like a small point and it is not. The supplements I have quietly stopped giving over the years were the ones that ran out and needed replacing in a hurry.
I cannot tell you the oil touched his hips. I can tell you my hand comes away clean when I ruffle his back.
The EPA and DHA are on the label, not buried in a blend
The bottle reads 1380 mg fish oil for dogs, with EPA and DHA named. I spent most of 2024 squinting at the backs of joint chews trying to work out what was in them and how much. Dr. Amundsen read every one of those labels before Biscuit started anything, and this is the one she kept coming back to. Sometimes a short label is the whole recommendation.
Triglyceride form, which is the line my vet checked
The listing says the oil is in the triglyceride molecular form, the form naturally found in fish. I am not a veterinarian and I am not going to pretend I follow the chemistry better than she does. What I know is that Dr. Amundsen turned the bottle over, read that line, and nodded. When your vet reads a label and sets it back on the counter without a lecture, that is your answer.
Nothing artificial in it, which mattered at his age
No artificial colors, flavors or preservatives, and it is non-GMO, gluten free and dairy free. At ten years old I did not want to be piling extra ingredients into a dog already taking four other things every morning. The shorter the list, the less I lie awake wondering about it at two in the morning. That is not science. It is what a person does when the dog is old.
It gave me a second thing to watch besides the stairs
Most of my log is stairs and walks. The oil gave me a line I could actually see change, and it was not the line I wanted. Week eight: coat softer, less flaking along the back. That is a modest win and I will not dress it up as more. But when you are watching a dog get older, one thing that visibly improved is worth something to the person holding the pen.
It is the one I would keep even though it did not fix his hips
If you are reading this hoping fish oil will get your dog up off the floor, let me be plain. It did not do that for Biscuit. His Cosequin did more for his mornings and I have said so. I keep the Nordic Naturals because his coat is better, because Dr. Amundsen recommended it, and because a fish oil is a reasonable thing to have in an older dog's bowl. That is the whole of my case.
What I'd Skip
A few things I would not spend on. I would skip anyone who tells you fish oil replaces what your vet prescribes, and I would skip the chew that promises the world in big letters on the front of the bag. I would also skip starting three supplements in one month. I added mine months apart precisely so the log could speak, and even then I cannot prove which one did what, because all five are still in the bowl today. Ask your own vet before you add anything, including this. Supplements support a dog. They do not treat arthritis, and no bottle has ever made an old dog young again.
Twenty two months in, the bottle is still in my refrigerator door
Nordic Naturals Omega-3 Pet is an unflavored liquid fish oil for dogs, eight ounces, poured over breakfast kibble. It is not the thing that fixed Biscuit's hips. It is the thing his vet asked me to keep, and the one I would buy again.
