Can Dogs Eat Salmon? Cooked, Plain, and Never Raw

Quick Facts

This is our own research, not veterinary advice. For nearly every food there are many sources, and they do not always agree with each other. We check each claim against the veterinary and poison control sources, and we say plainly where they disagree. Even so, if you are in any doubt, contact a vet and do your own research before you feed anything to an animal in your care.

Salmon is safe for dogs once it is cooked and plain, and raw salmon is the one fish to refuse outright, because it can carry a parasite that causes a disease that is fatal if it is not treated. The problem in practice is not the fish at all. It is that salmon is usually seasoned for a person, and salt, lemon and garlic are the things that make it a bad idea.

This is the page where the honest answer is that we mostly do not give salmon at all, and the reason is not the fish.

If you are interested in getting into house sitting, our book Travel More for Less puts the whole process in one place: clear, step by step guidance from your first questions to your first confirmed sit, and the reviews that open the door to the next one.

Can Dogs Eat Salmon? Cooked and Plain, Never Raw

Cooked, boneless salmon is safe, and weekly portion ranges by dog size are given below. The omega-3 content is the nutritional case for fish generally.

Salmon is absent from the poison control avoid lists. Raw or undercooked meat, eggs and bones are covered as a category, and no fish appears at all. So a dog eating cooked salmon is not on anybody's hazard list, and that is an absence of warning rather than a positive clearance.

The verdict is straightforward: cooked, plain, bones out. The complications are all about the other two words.

Raw Salmon and Salmon Poisoning Disease

This is the one genuinely serious thing on the page. Raw salmon can make a dog very sick, it can carry a parasite which causes salmon poisoning disease, and the disease can be fatal if it is left untreated.

The detail is worth having, because this is a disease with a name, a vector and a treatment. It is caused by Neorickettsia helminthoeca, a bacterium transmitted by the intestinal fluke Nanophyetus salmincola. The fluke needs a snail as its first host and a fish as its second, which is why the disease tracks raw or undercooked fish, and why salmon and trout are the usual route.

The veterinary manual describes the onset as sudden, usually five to seven days after the fish was eaten, with a high fever, vomiting, bloody diarrhoea, severe dehydration and generalised swollen lymph nodes. Left untreated, the mortality rate is around 90% within seven to ten days, from dehydration and anaemia.

It is treatable: doxycycline or tetracycline for at least seven days, alongside intravenous fluids and antiemetics, which is why the advice is to ring a vet rather than to wait and see. It is also preventable, because cooking or freezing the fish destroys the infectious agent. The warning is consistent across the veterinary sources and stated in the strongest terms, and the underlying science is real, even though the detail is reported from the veterinary manual rather than quoted from a page we read ourselves. For a house sitter the practical instruction does not depend on the detail: raw fish does not go to the dog.

One thing worth adding is that this is a different risk from the bacterial one. Raw meat and fish are also a salmonella and E. coli risk, which is a food hygiene problem. Salmon poisoning disease is a fluke-borne bacterium, and it is a separate reason not to feed raw fish.

The Seasoning Is the Real Problem

Here is the part that matters more than the fish, and it is the reason we rarely give salmon on a sit.

When most people cook salmon, they cook it to eat. That means salt, usually lemon, often pepper, and quite often a garlic or onion element in a marinade, a rub or a sauce. Every one of those is a problem, and garlic is the worst of them.

Onion, garlic and chives are a single category of risk, causing gastrointestinal irritation and damage to red blood cells that can lead to anaemia, and cats are more susceptible than dogs. A piece of garlic seasoned salmon is a genuinely bad thing to hand a cat. Salt is a separate problem, with signs that run from vomiting and diarrhoea up to tremors, seizures and death.

So the question is not whether salmon is safe. It is whether the salmon in front of you is plain, and on a normal evening in a normal kitchen it is not.

The Fish We Actually Give: Sardines

If you want to give a dog fish, sardines from a tin are the easier answer, and this is what we reach for.

The reasons are practical rather than nutritional. Sardines are small, so the bones are small and soft, and they do not present the blockage and perforation risk that a larger fish bone does. They come in brine or in olive oil, and if you rinse the oil off you are left with fish and very little else. And they are already cooked, which removes the raw parasite question entirely.

The thing to check is the tin. Sardines in brine are salty, so rinse them. Sardines in olive oil are better for a dog than most tinned fish, but you still do not want the oil, which is a lot of fat in a small package. What you want to avoid is anything smoked, anything in a tomato or mustard sauce, and anything with added salt or flavourings.

One or two sardines is a portion for a medium dog rather than a snack, and they are rich enough that a dog not used to them will let you know about it. If a dog will not take a tablet, a sardine is also one of the more reliable ways to hide it, which the medication page covers in more detail.

How Much Salmon Is Safe

Cooked farmed Atlantic salmon is 206 kcal per 100 g, and about 12 g of that is fat. That is a rich food, roughly four times the calorie density of chicken, and the fat is why it is a treat rather than a meal.

The guidance is weekly rather than daily, from 28 to 57 g (1 to 2 oz) for a dog between 1 and 9 kg (2 and 20 lb) up to 170 to 227 g (6 to 8 oz) for a dog over 41 kg (90 lb). Those are weekly totals, which tells you something in itself about how rich the food is.

Those calorie figures are our arithmetic on the values above. The point they make is that salmon does not behave like a treat. A piece the size of a thumb is most of the day, and the weekly ranges exist because a dog cannot have this daily.

The 10% rule we use everywhere is treats under about 10% of a dog's daily calorie intake. Salmon is rich enough that a portion on top of a full dinner will take up a large share of it.

Salmon Skin, Smoked Salmon and Canned Salmon

Skin is where most of the fat sits, which makes it the least useful part for a dog and the most likely to cause a stomach upset. If you are giving salmon, give the flesh and leave the skin.

Smoked salmon is the one to refuse outright. Our reasoning is the salt and the fat rather than the smoke, and the salt is enough on its own to put it in the same category as bacon.

Canned salmon is closer to fine, because the bones are softened and edible and it is already cooked. But check the tin the same way you would check a sardine tin: water or oil rather than brine, and no added salt or flavourings.

If a Dog Has Eaten Raw Salmon

Ring a vet and say that it was raw fish and roughly how much. Do not wait for symptoms before making the call, because this is one of the cases where the advice is time sensitive.

The signs to watch for are vomiting, diarrhoea, a high temperature, loss of appetite and lethargy, and they can appear anywhere from about five days to a few weeks after the fish was eaten. That delay is the reason we are telling you to ring rather than to observe.

If the fish was cooked and seasoned instead, the concern is the seasoning rather than the parasite, and what to do when a pet eats something dangerous covers that sequence.

Where This Research Comes From

What this page cannot tell you: no source addresses smoked salmon or cats, so those answers are our reasoning rather than a citation. The salmon poisoning detail is reported from the veterinary manual rather than quoted from a page we read ourselves.

Conclusion

Cooked plain salmon is safe for a dog, and raw salmon is not. Between those two facts sits the real issue, which is that the salmon in a normal kitchen is seasoned for a person, and salt and garlic are the things that turn a good food into a bad one.

So the useful answer on a sit is this. Leave the fillet alone, and keep a tin of sardines in the cupboard instead.

Caro and I have completed 20 house sits across 12 countries, driven 19,000km across Europe in our 1998 VW T4, and saved over $26,500 in accommodation costs over three years of house sitting.

We are not vets. This page is our own research, and every source behind it is listed at the bottom so you can check any of them yourself.

If you have a question about a specific animal, a vet beats every page on the internet, this one included. If you have a tin of sardines in your cupboard for exactly this reason, you are our kind of people, and you can DM us @housesittersguide, we answer everyone.

Frequently Asked Questions

• Can dogs eat salmon?

  Yes, as long as it is cooked, plain and boneless. Cooked salmon is treated as safe, with weekly portion ranges given by dog size.

• Can dogs eat raw salmon?

  No. Raw salmon can carry a parasite which causes salmon poisoning disease, and the disease is potentially fatal if untreated. It is the one clear refusal on this page.

• Can dogs eat salmon skin?

  We would not. The skin is where most of the fat sits, and fat is the part most likely to cause vomiting or diarrhoea. Give the flesh and leave the skin.

• Can dogs eat smoked salmon?

  Nothing addresses it. Our own answer is no, on the salt and the fat rather than the smoke, and the salt alone is enough to put it in the same bracket as bacon.

• Can dogs eat canned salmon?

  It is closer to fine than fresh salmon is, because it is cooked and the bones are softened. Check the tin the way you would a sardine tin: water or oil rather than brine, and nothing added.

• How much salmon can a dog have?

  The portions are weekly totals rather than daily ones, from 28 to 57 g (1 to 2 oz) for a small dog up to 170 to 227 g (6 to 8 oz) for a dog over 41 kg (90 lb). Our arithmetic on the published figure puts 30 g at a large share of a day's intake, so a thumb sized flake is the realistic portion.

• Can cats eat salmon?

  Cooked and plain, yes, and the same rules apply. Cats are more susceptible to onion and garlic than dogs, so a piece of seasoned salmon is a bigger problem for a cat than for a dog.
