Can Dogs Eat Tuna?

Have you ever pondered the question: Can dogs eat tuna? Or are you thinking of feeding tuna to your dog?

If you answered yes, you’ve come to the right spot. We’ve done the research, so all you have to do is sit down and read the article.

Dogs live on land, but fish dwell in water, therefore there is a significant difference between the two creatures. So it must be a generic question, one thinks of. 

Humans commonly ingest fish such as tuna or salmon; but because a dog’s anatomy differs from that of humans, feeding your pet dog tuna in large quantities is unhealthy.

Sadly,  this is not a Dr. Suess novel, so brace yourself for a bumpy journey.

Can Dogs Eat Tuna?

If you’ve been wondering if your dog can eat tuna, the response is “yes,” but with a word of caution: only in small quantities.

Tuna should not be included in your dog’s meals on a frequent basis.

Heavy metals and pollutants enter saltwater and pollute it, therefore tuna fish will ingest more metals in their system as long as they are in the ocean.

Since saltwater contains many of these substances that enter the fish’s body, they remain in the system, and in turn, enter the body of your dog when they are consumed.

Fish, particularly larger ones like tuna, have a lot of mercury stored up in their tissue, which can cause mercury poisoning and be extremely harmful to your dog.

Despite being a fantastic source of protein and omega fatty acids, it is typically a good idea to keep the pet’s tuna eating to a minimum.

Can Dogs Eat Raw Tuna?

Okay, I’m quite sure everyone enjoys eating sushi. Am I right? or am I right?

But that isn’t always the case for your dog.

Raw tuna fish can contain more quantities of mercury than cooked or canned tuna.

Despite the fact that fish is an excellent source of protein, it should be fed with caution.

Yes, dogs have powerful stomach acids that aid in food digestion and destroy bacteria, but raw tuna contains intestinal parasites that can still wind up in the stomach when consumed.

Feeding raw tuna fish to your dog might be dangerous if intestinal parasites enter your dog’s stomach.

If you have to feed raw tuna to your canine, do so with extreme caution and keep a check on his health

Because skipjack and albacore tuna have the lowest mercury levels, these fish are a good choice.

Feeding Tuna To Your Dog

Now that we’ve discussed “Can dogs eat tuna fish” and “Can dogs eat raw tuna fish”, let’s talk about how to feed tuna to your canine

Canned Tuna

Just like the tunafish sandwich said, I’ve got a feeling we’re not in cans-us anymore.

When considering whether to give tuna, there is always the choice of giving canned tuna.

Keep in mind the tuna you give your canine is canned in water or brine rather than sunflower oil, which can trouble his tummy. 

Don’t give your dog any canned tuna with spices or flavorings, as these can make him very sick. 

Never feed your dog any vegetable condiments like tomato, onion, or garlic, as these can be toxic.

When feeding canned tuna, use smaller tuna fishes since larger tuna fishes contain higher mercury residues in their bodies.

Another thing to consider when feeding canned tuna to your dog is the canned tuna sold in stores is extremely salty which is not healthy for dogs.

When it comes to dogs, canned tuna with a lot of salt can cause dehydration, excessive water intake, and internal health problems.

Tuna Grilled, Baked, and Cooked

Cooked tuna should be fed to your dog, and raw tuna should be avoided at all costs if possible.

Cooking, grilling, and baking tuna are some of the ways you can offer tuna to your dog, and canned tuna is always an option.

The tuna fish’s fins, tails, bones, and head should not be fed to your dog since they might cause choking and internal bleeding.

Remember to feed the tuna in reasonable portions, even if it is cooked. And if this is your dog’s first time eating tuna, feed a very little portion to see if your doggy likes it. If he does, you can continue feeding him.

How Much Tuna Can You Feed Your Dog?

As previously said, the amount of tuna that can be offered to your dog should be very little to moderate, but here is a more thorough breakdown:

You can restrict the amount of tuna you provide based on your dog’s weight.

Larger dogs are more accustomed to eating tuna than smaller kinds of dogs

You should never feed your canine more than a tablespoon of tuna in a week. A can of tuna is sufficient for a month and should never exceed that.

It is not recommended to feed tuna to a puppy.

When giving tuna to your dog,  make sure to keep an eye on the health of your canine.

Can My Dog Be Allergic To Tuna?

Although it is uncommon for dogs to be allergic to fish, it is possible.

Because many dogs are allergic to other protein sources such as beef and chicken, fish is becoming a more popular protein source in dog foods. 

Since feeding fish to dogs is becoming more common, an increasing number of dogs are being diagnosed with fish allergies.

Some of the symptoms that may appear after your dog consumes fish, including tuna fish, are as follows:

  • Skin itch
  • Vomiting
  • Diarrhea
  • Fur thinning

Along with more serious symptoms such as anaphylaxis, hives, and swelling.

So, if you see any of these symptoms and suspect that your dog is allergic to tuna, you should contact your veterinarian as soon as possible. 

Feeding tuna to your dog in large quantities can be harmful, so feeding small quantities such as one tablespoon is the right amount. 

Another thing to remember is that you should never feed your dog more than a tablespoon of tuna per week, and a can of tuna is enough for a month and should never be exceeded.

When it comes to feeding, raw tuna fish can contain more mercury than cooked or canned tuna. 

Heavy metals and pollutants enter saltwater and pollute it, so tuna fish will absorb more metals in their system as long as they are in the ocean.

Finally, while tuna is a terrific source of protein, minerals, and vitamins for your dog; it should be fed in small amounts and in moderation.

And a word of caution to pet parents who also have cats at home: make sure your dog is not ingesting your feline’s food, as cat food contains fish which can be harmful to your dog.
