Can Dogs Have Tuna Fish – What You Need To Know

If you’re a dog owner, then you’ve likely asked yourself at some point whether or not it’s safe for your furry friend to eat tuna fish.

And if you haven’t, well, here’s everything you need to know about whether or not dogs can have tuna fish.

Spoiler alert: they can! But as with any human food, there are certain things you need to keep in mind before feeding your pup this tasty seafood dish.

So without further ado, let’s take a closer look at the pros and cons of giving your dog tuna fish, and how to serve it to your dog – the safe way!

Can Dogs Have Tuna Fish – Everything You Need To Know

Tuna fish is a type of saltwater fish that is commonly consumed by humans as part of a healthy diet.

It’s ok for dogs to eat – but in small amounts – as it’s an excellent source of protein, omega-3 fatty acids, and vitamins and minerals – like magnesium, potassium, and selenium.

Omega-3 fatty acids are especially beneficial for dogs, as they help to support a healthy coat and skin, as well as joint health.

Tuna fish is also relatively low in mercury compared to other types of seafood – making it a safer choice for dogs (and humans!) than some other seafood options.

However, there are a few things you need to keep in mind before feeding your dog tuna fish.

First and foremost, tuna fish – like all seafood – can contain harmful bacteria that can make your dog sick.

That’s why it’s important to only feed your dog cooked tuna fish, as cooking will kill any harmful bacteria present in the fish.

Second, tuna fish – especially canned tuna fish – often contains added salt, which is not good for dogs in large amounts.

So if you’re feeding your dog canned tuna fish, be sure to choose a variety that is labeled ‘low sodium’ or ‘no salt added.

Thirdly, it is high in sodium which is not good for dogs with certain medical conditions like heart disease, kidney disease, or high blood pressure.

And last but not least, tuna fish – like all seafood – can contain harmful toxins like mercury and polychlorinated biphenyls (PCBs).

While the levels of these toxins are usually low in tuna fish, they can still be harmful to dogs – especially in large amounts.

So if you’re feeding your dog tuna fish, be sure to choose a variety that is labeled ‘low mercury’ or ‘no mercury added’.

Health Risks of Dogs Eating Tuna Fish (Due to Mercury Poisoning)

Let’s take a closer look at the potential health risks associated with feeding your dog this seafood dish.

As mentioned previously, tuna fish can contain harmful toxins like mercury and polychlorinated biphenyls (PCBs).

While the levels of these toxins are usually low in tuna fish, they can still be harmful to dogs – especially in large amounts.

The most common health risk associated with feeding your dog tuna fish is mercury poisoning.

Symptoms of mercury poisoning in dogs include:

• Diarrhea – this is the most common symptom of mercury poisoning in dogs.
• Vomiting – is another common symptom of mercury poisoning in dogs.
• Lethargy – dogs with mercury poisoning may be more tired or ‘sluggish’ than usual.
• Loss of appetite – some dogs may lose their appetite altogether when suffering from mercury poisoning.
• Tremors – some dogs may experience muscle tremors or ‘twitching’ as a result of mercury poisoning.
• Anxiety – some dogs may become more anxious or ‘jumpy’ when suffering from mercury poisoning.
• Kidney damage – in severe cases, mercury poisoning can lead to kidney damage.
• Hair loss – although not as common, some dogs may experience hair loss as a result of mercury poisoning.
• Blindness – this is a very rare but potentially serious symptom of mercury poisoning in dogs.

My Dog Ate Tuna Fish – What Now?

• Small amounts – don’t worry

If your dog ate a small amount of tuna fish – especially if it was cooked – chances are they will be just fine.

However, it’s always a good idea to keep an eye on your dog for any potential symptoms of mercury poisoning – like diarrhea, vomiting, or lethargy – just to be safe.

If your dog does experience any of these symptoms, call your veterinarian right away.

• Large amounts – go to the vet

If your dog ate a large amount of tuna fish – especially if it was raw or canned – and is showing any of the above symptoms, it’s important to seek veterinary attention as soon as possible.

During a physical examination, your vet will likely look for signs of dehydration – such as sunken eyes, dry gums, or skin that ‘tents’ when pinched – as well as any potential neurological symptoms – like tremors, seizures, or blindness.

Of course not all fish are created equal – some are very healthy and safe for dogs to eat. So what types of fish are safe for your dog to eat?

Some of the best (and safest) fish for dogs include:

Salmon – this fish is packed with omega-3 fatty acids and is a great source of protein. This type of fish is also relatively low in mercury.
