People have different opinions on whether dogs should eat tuna or not. Some say it’s fine and even use it in dog food. But when it comes to giving tuna as an extra treat, experts don’t all agree. Some say it’s okay, while others suggest not adding more tuna to your dog’s meals.

Overview: Can Dogs Eat Tuna?

Can Dogs Eat Tuna

It’s okay to give your dog a bit of tuna as an occasional treat, but don’t make it a regular food. Tuna has good stuff like protein and omega-3 that helps keep your dog healthy. But, be careful because tuna also has something called mercury, which can be bad for your dog’s health if they eat too much of it over time.

Some dog foods have tuna, but it’s better not to give it to your dog every day. If you want your dog to have fish regularly, pick dog food with fresh fish that doesn’t have a lot of mercury.

Also, pay attention to the kind of tuna you’re giving. Canned tuna can be in brine, springwater, or oil, and each one has different things to consider for your dog. And there are different types of tuna in the ocean. So, if you’re wondering what kind of tuna is good for your dog, it depends on the species.

Now let’s address some of your questions in detail.

Can Dogs Eat Canned Tuna?

Feeding your dog a bit of canned tuna can be a good and healthy treat. Pick tuna in water, not oil, and go for albacore or skipjack kinds instead of big ones (like bigeye or bluefin) to have less mercury in each serving.

However, canned tuna is often high in salt, which isn’t good for our furry friends. You can find cans with no added salt, and these are a better choice if you want to share tuna with your pup.

Some canned tuna has added herbs and spices, which might taste good to us but can make your dog sick. So, avoid giving your dog tuna with extra seasonings. Apart from the type of tuna and added spices, canned tuna comes in different liquids—brine, sunflower oil, or freshwater. Which one is safe for dogs?

Can Dogs Eat Tuna Steak?

Tuna steak is a bit tricky for dogs. Some people really like bluefin tuna, especially when it’s raw in sushi. But for your furry friend, it’s not safe to give them raw tuna because it might have parasites and could upset their stomach. Also, avoid giving them bluefin tuna because it has too much mercury.

But, if you have tuna steak from types with less mercury, like Albacore or Skipjack, it’s okay to share a bit with your dog. These types are usually found in canned tuna steak. Just make sure to cook it before giving it to your pup, and don’t add any extra stuff to it.

Can Dogs have Tuna in Brine?

A small amount of tuna in brine is okay, but it’s best not to give it to your dog. It has a lot of salt, which can be harmful and cause sodium poisoning. Tuna in sunflower oil is a bit safer, but the best choice is tuna in spring water. It has less salt and fat compared to other types of canned tuna.

Can Dogs have Tuna in Sunflower Oil?

If you drain the fish well, it’s safe for your dog to have a little tuna in oil. Sunflower oil is lower in bad fat and can even be good for your dog’s fur in small amounts. But too much oil can lead to weight gain and inflammation. Sunflower oil has omega-6, which is good for your dog, but it needs to be balanced with omega-3 to prevent inflammation and immune issues.

While a bit of tuna in sunflower oil is safe, the best choice is tuna in spring water for your dog.

Nutritional Benefits of Tuna for Dogs

There are safer options like salmon if you want to add something nutritious to your dog’s diet.

Don’t give tuna to puppies, even a small amount once in a while. Mercury poisoning is a serious risk, especially for small breeds and growing puppies.

Dogs can have canned tuna, but not too much. Pick the one in water, not oil or salted water. Check the label to be sure there’s no extra salt added. Don’t give your dog raw tuna. Raw fish might have bad stuff that can make your dog sick. There’s also an enzyme in raw fish that stops vitamin B1 from working. Cooking the fish solves this, so make sure tuna is cooked before giving it to your dog.

Health Risks of Tuna for Dogs

It’s not a good idea to give your dog tuna because it can make them sick. Tuna has some things that can hurt your dog, like too much mercury. Mercury is a kind of stuff in the fish that can make your dog very sick. It can make them have problems like diarrhea, shaking, or throwing up blood.

Sometimes, fresh tuna can have germs that are not good for your dog. These germs can make your dog sick for a long time and give them health problems.

Also, tuna has too much fat. Too much fat is not good for your dog because it can make them have trouble digesting their food or make them gain too much weight. It’s better to give your dog homemade food or food made for dogs from the store.

Tuna could Lead to Mercury Poisoning

The impact of mercury on pets mirrors its effects on humans. It may induce digestive issues and harm vital organs such as the kidneys and the brain. In the unfortunate event of breaking an item containing mercury at home, if your pet is in proximity, there’s a risk of mercury residue adhering to their paws or fur.

Tuna fish has more mercury than many other fish, and if animals eat too much, there’s a risk of mercury poisoning. Mercury is a pollution that goes into the oceans, where fish like tuna absorb it. Tuna can live a long time, like up to 40 years, so they gather a lot of mercury in their bodies over time.

It’s not common, but dogs can get sick or even die if they eat too much tuna, especially if the tuna has a lot of mercury in it. Mercury is a harmful substance that can seriously hurt dogs and even lead to their kidneys failing.

But not all tuna is the same – some kinds have more mercury than others. How much danger there is depends on the type and how much tuna a dog eats. Usually, it’s okay to give your dog a little bit of cooked tuna as a special treat, but don’t make it a regular part of their meals. Be extra careful with small or young dogs, or those with health issues – they shouldn’t have any tuna at all.

If you see anything strange in your dog that makes you think they’re reacting badly, talk to your vet.

Feeding tuna to your dog in small amounts and not often is not likely to cause mercury poisoning. Still, it’s smart to check with your vet before adding tuna to your dog’s meals. They can suggest the right amount based on your dog’s weight and health.

Pathogenesis in Animals

Physical and chemical properties influence the impact of mercury forms on animals. Organic forms, particularly methylmercury, exhibit extensive bioaccumulation in tissues like the brain and kidney. Methylmercury disrupts metabolic activity, leading to degeneration, necrosis, and various pathological findings.

Fish bones can be a danger. Tuna, like other fish, can have small bones that might make your dog choke or harm their digestive tract. Before giving tuna to your dog, check for bones and take them out.

Tuna has a lot of salt. Some experts say no to dogs eating tuna because of this. But if you give only a little bit, your dog can enjoy tuna from time to time without problems.

If your dog eats too much tuna, it can be really bad. It might hurt their kidneys and make them blind. So, try not to give tuna to your dog, or at least give them just a little bit sometimes. It’s safer that way.

Treat Mercury Poisoning in Dogs

Can Dogs Eat Tuna

If you think your dog ate a lot of tuna and might have mercury poisoning, call your vet right away. Getting help early is important to lower the chance of lasting problems and improve the chances of your dog getting better.

The treatment for mercury poisoning in dogs depends on how bad it is and what symptoms your dog shows. Sometimes, the vet may give fluids through a vein and medicine to stop vomiting and diarrhea.

If the poisoning is really bad, your dog might have to stay in the hospital. There, they can get medicines that stick to the mercury and take it out of the body, like charcoal. In some cases, dogs may even need dialysis to clean the toxin from their kidneys.

Prevent Dog from Eating Tuna

It can be a challenge to keep dogs away from food they’re not supposed to eat. For example, you may also have a cat who eats wet food containing tuna. If your dog tends to get into the cat’s food, try feeding them in separate rooms blocked by a door or gate. Also consider feeding your cat a wet food made with another type of fish.

Although less common when compared with dogs, cats can get mercury poisoning from eating tuna over the long term as well.   If your dog loves seafood, there are many options besides tuna to satisfy their cravings. Consider other types of fish that are appropriate for dogs, such as salmon or whitefish. Many dog foods are made with fish ingredients that are okay for pups to enjoy.  

Raw Tuna for Dogs

Raw fish, including tuna, may have harmful parasites or bacteria that can make your dog sick. Additionally, raw fish contains an enzyme called thiaminase, which can prevent the absorption of vitamin B1. Cooking the fish solves this issue, so it’s important to make sure tuna is fully cooked before including it in your dog’s meal. This helps keep your furry friend safe and healthy.

Tuna’s high mercury content stems from the accumulation of heavy metals like mercury and lead in the ocean. Fish with longer lifespans accumulate more of these metals due to continuous exposure. Tuna, being a large and long-lived fish, contains higher mercury levels, making moderation crucial to avoid mercury poisoning.

Accidental Consumption: What to Do?

If your dog inadvertently consumes a small portion of cooked or canned tuna, there’s no cause for major alarm. Mercury toxicity is unlikely in such cases. Yet, contact your vet if your dog consumes raw tuna or if they exhibit an allergy to it.

It’s okay for your dog to have a bit of tuna now and then as a treat. However, giving them a lot or too often can be risky. If your furry friend manages to snatch a whole can of tuna, they might end up with a tummy ache, especially if it’s packed in oil instead of water. Dogs could even get pancreatitis from tuna in oil.

Watch your pet closely if they eat a bunch of tuna, especially the kind with more mercury, like albacore tuna. If you see an

Safer Alternatives: Fish for Dogs

Can Dogs Eat Tuna

Which fish are safe for dogs to eat? Generally, it’s safer for dogs to eat smaller, wild-caught fish because they usually have lower levels of harmful mercury and fewer parasites. Here is a list:

Fish Type

Which fish should dogs avoid? Some fish species like shark, swordfish, king mackerel, and tilefish are not suitable for dogs. These fish are usually caught when they are bigger and older, which makes them more likely to have high levels of mercury and carry parasites in their skin, muscles, and internal organs.

Avoid giving your dog farm-raised fish too. These fish can contain harmful dyes, leftover antibiotics, and other toxins once they are harvested and processed.

How Much Tuna is Okay for My Dog to Eat?

Tuna has good stuff for your dog, but too much can be bad because of mercury. So, just give it sometimes, not every day. A small bit, like one tablespoon, is good. See how your dog reacts the first time you give it. If there’s a problem, you’ll probably notice within a day.

Big dogs can have one can of tuna in a week, but not every week. Smaller dogs can have about half a can in a week. Ask your vet about how much tuna is right for your pet. They’ll know based on your pet’s size, weight, and health needs.
