Natural Dog Company Salmon Oil Honest Review: Pros and Cons

I kept the receipt in the kitchen drawer for months, which tells you how much I expected from a bottle of fish oil. I started the Natural Dog Company Wild Alaskan Salmon Oil in January 2025 because Dr. Amsel, Hattie's vet since she was a puppy, went through every label on my counter and said fish oil was the one he would add if she were his. Hattie is a ten-year-old golden retriever, sixty-eight pounds, with arthritis in both hips that showed up on X-rays in September 2024. By the time I bought this, I had spent three months watching her stand at the top of the four wooden steps off our back deck and think about it before she went down.

So this is not a review written from a product page. It is what twenty-two months of two pumps a day over dinner looked like in a house with one dog, a coach's clipboard on the counter, and a husband who handles the evening meal once in a while. I write down how Hattie gets up, how she does on the deck steps, and how far we walk. That clipboard is the only reason I can tell you anything at all, including the parts that are not flattering to the product.

How I've Used It

Two pumps a day at her weight, over dinner, and that has not changed in twenty-two months. Breakfast is a separate operation in our house, so the salmon oil goes on the evening meal, pumped straight onto the kibble and stirred once with a fork. Hattie is not a picky dog and she has never turned her nose up at it. Dan does dinner on the nights I am out, and he can do it without asking me anything, which is a small thing that matters more than it sounds when you are keeping track of five different containers.

The bottle is sixteen fluid ounces with a pump in the neck, and in our house it lives in the refrigerator door after it is opened. The label says a cool, dry place. I put it in the door anyway, because I spent thirty-one years watching what heat does to things that contain oil, and because I would rather be wrong about storage than wrong about a bottle going off in my pantry. That is my call, not a direction from the company. If you keep yours in a cabinet, you are following the label more closely than I am.

The first night I primed the pump over the sink, six or seven presses before anything came out, and then set the bottle down and read the weight chart on the label twice before I trusted myself. Two pumps. That was it. I stood there feeling slightly foolish that a thing I had worried about for three months took about four seconds. Dan's first attempt, a week later when I was at a school reunion, went fine, which is more than I can say for the first time he tried to level a scoop of the mussel powder.

Two pumps is the amount for her weight and I want to be plain that I am not measuring it in a laboratory. It is two presses of the pump into the bowl. That pump has given me the same two presses every night for nearly two years, without clogging or spitting or half a dose landing on the counter. That sounds like nothing to praise. It is not nothing. I have thrown out a supplement I liked because the scoop was impossible to fill evenly, and I have complained about it to anyone who would listen.

What Changed and What Didn't

Here is the honest part, and it is the reason I am writing this instead of just telling you to buy it. I saw no joint change that I could point to. Nothing on the clipboard moved in February or March or April of 2025 that I could credit to this bottle. She was still slow off the floor in the morning. She was still thinking about the deck steps before she took them. The walk did not get longer.

I will give you one specific morning instead of a vague impression. It was the second week of March 2025, still cold enough for a coat, and I stood at the kitchen window with my coffee and watched her come down the deck steps. She took them the way she had taken them in December. No shorter pause at the top, no change in how she placed that back left foot. I wrote down the same line I had been writing since January, and then I made a second note underneath it that said the coat looks better.

What did change was the coat. By about eight weeks in, the flaking along her back was gone and her coat had a shine to it that I had not seen since she was seven. That is a real thing that happened, and I wrote it down. It is also not the reason I started the bottle, and I am not going to pretend it was. If you are buying this for a stiff dog, understand that the improvement I can actually document is cosmetic. That is worth knowing before you order, not after.

By then she was already on the VetIQ chews, which she started in October 2024 on Dr. Amsel's suggestion, and those are the ones that got the first change on the clipboard at six to eight weeks. So I cannot tell you the salmon oil did nothing for her joints. I can only tell you I could not see it while everything else was happening around it. There is a difference between a review and a claim, and I am not going to blur it for you to make a nicer paragraph.

The improvement I can document is a coat that stopped flaking. The improvement I hoped for is one I cannot prove, and I am not going to dress it up.

Reading the Label Without the Marketing

Natural prints the active ingredients plainly on the back panel: EPA, DHA, omega-3 and omega-6. The benefits line covers antioxidant support, digestive health, heart health, immune support, joint health and skin care. I read that as a list of things fish oil is generally thought to help with, not as six promises about my dog. The joint health line is the one that got me to buy. The skin care line is the one that turned out to be true for us. Both of those can be true at once, and a label that lists six benefits is not lying when only one of them shows up on my clipboard.

The bottle is sixteen fluid ounces, about eight inches tall and two and a half inches wide, and it arrives with the pump in the neck. The label says it suits small, medium and large breeds, which is a way of saying the amount is dosed by weight and you should read the chart rather than guess. I would say what Dr. Amsel says about everything on my counter: the amount on the label is a starting point, and your vet knows your dog's weight and bloodwork better than a bottle does.

It is an oil. Not a chew, not a powder, not a capsule. That matters more than people expect. A dog who will not take a tablet will usually take oil mixed into food. A dog with a touchy stomach may not, and if I were starting over I would introduce it slowly over a week rather than going straight to the full amount. Natural calls it a food topper and that is exactly how it behaves in our house. It is not a meal and it is not a medicine. It goes on top of dinner and disappears into it.

The Parts Nobody Mentions

It smells like fish. Not faintly. The refrigerator door smells like fish, and Dan has opinions about it going onto the kibble while he is eating his own dinner at the same table. Hattie does not care in the least and has never once left a bite behind. If smell is going to bother you at seven in the evening, that is a real cost of this product and you should know it before you order rather than after.

Second thing. Nothing about this replaced anything else. It did not replace the chews, the mussel powder, the hyaluronic acid or the turmeric. It sits alongside all of them. I started it because my vet recommended it, and I have kept it for twenty-two months because my vet recommended it and because her coat looks better than it did. That is a quieter reason to keep buying something than most reviews will give you, and it is the true one.

Third thing. It is not a pain reliever and I would be careful with anyone who tells you it is. Hattie still has arthritis in both hips, worse on the left. She is still slow coming up the deck steps. Cold, wet mornings are still her worst. No bottle in my kitchen changed that, and I have five of them lined up on the counter with her name on the list taped to the cabinet door.

Fourth thing, and it is a small one. A sixteen ounce bottle does not announce itself when it is running low. I check the level every Sunday when I write the shopping list, and twice I have caught it with about two nights left in it. Neither time was a crisis because I ordered in time, but if you are the sort of person who notices a thing is gone only when it is gone, put a reminder in your week and thank me later.

How It Fits With the Other Four

I added five things over about fifteen months, one at a time and months apart, so the clipboard had a chance to show something. That was the plan and it was a reasonable one. What I did not account for is that once all five are running, none of them can be measured alone. VetIQ came first in October 2024 and is the only one I will say worked first. The salmon oil came in January 2025. Super Snouts came in April 2025, LubriSyn in August 2025, and the turmeric this past January.

So when somebody asks me which one to buy, I have to say what I actually know. I know the order they went in. I know what the clipboard looked like after each one. I know the walk went from about fifteen minutes in September 2024 to about twenty-five by the summer of 2025 and has held there since. I cannot hand any single container credit for that, and neither can anyone who is selling you one. Anyone who tells you otherwise is guessing with confidence.

What I Would Do Differently

I would have started the salmon oil first. Of the five, it is the one my vet brought up without being asked, and it is the easiest to serve because it is liquid and it goes on food that is already in the bowl. Starting it before the chews would have given me a cleaner eight weeks to look at. I did not do that, and I am not going to invent a result to cover for it.

I also would have taken a photograph of her back on day one. The coat change is the one thing I can honestly claim and my only evidence is a clipboard line that says back looks better, no flaking. A picture from January 2025 next to a picture from March 2025 would have ended the argument in my own head. If you are starting this tonight, take the photograph tonight.

Who This Is For

This is for the person whose vet has already mentioned fish oil and who wants to know whether this particular bottle belongs on the counter. It is for a dog who eats dinner without drama and a household that can tolerate a fish smell in the refrigerator door. It is for someone who wants a topper they can pump and walk away from, not a capsule they have to hide in cheese twice a day for the rest of the dog's life.

It is also for the person who reads the word joint on a label and expects the joint to change. I did. My advice is to buy it for the coat and the omega-3s and because your vet suggested it, and then to write down what you see for eight weeks so that you know what you got. If the coat improves and the walking does not, that is still a real result. Count it honestly and decide from there.

One more thing on that. If your dog is already on four other things, as mine is, adding a fifth means being honest about what you will be able to measure. I added this one knowing it would disappear into the mix. Natural doses by weight and puts a chart on the label that covers small, medium and large dogs, which helps, but no chart can tell you what a fifth product did on top of four. I bought it anyway because my vet asked for it, and I would make that trade again.

Who Should Skip It

Skip it if your dog has a fish allergy, which sounds obvious until you are standing in a kitchen at seven in the evening with a pump in your hand. Skip it if your dog turns her nose up at wet food, because oil changes the texture of kibble and some dogs notice immediately. Skip it if you have a small kitchen and no tolerance for smell, or if the person doing the evening feeding is going to object to it every single night.

And skip it if you are looking for the one thing that fixes a stiff dog by itself. This is one line in a longer plan, and Dr. Amsel would be the first to say the plan matters more than any single container on my counter. Ask him before you start, the way I did. Ask him before you stop, too. He has looked at every label in this house and he has never once told me a bottle would do more than it can.
