Can Dogs Eat Tuna? (Solved & Explained!)

Dogs can eat tuna as long as it’s clean and certified to be free of any pollution in it. Since tuna fish can pick up pollution from the water in the wild, it’s argued that almost no type of tuna is completely safe unless it’s undergone a complicated purification process.

That being said, if your dog eats a little bit of tuna you dropped out of a can on the floor it’s likely that nothing bad is going to happen. Though dogs probably shouldn’t be eating complicated human foods like mayonnaise, your dog probably wouldn’t get all that sick even if he or she ate some tuna salad that happened to fall on the floor.

How Much Tuna Can You Feed a Dog?

The non-profit organization behind Consumer Reports has suggested limiting tuna consumption for humans to at least some degree, primarily as a result of pollution from power facilities and elsewhere that gets caught up in it. Considering how much smaller than humans puppies are, it’s a good idea to not give smaller dogs any tuna at all.

Larger dogs may be able to eat a small amount of it here and there, but keep in mind that tuna is actually pretty rich in oils so a large dog that ate a full can of tuna would likely get an upset stomach from it. On top of this, even the largest dogs shouldn’t be consuming that much fat in their diet because they can gain weight as a result.

Can I Give My Dog Canned Tuna in Water?

If you’re going to give your dog tuna, then you’d only want to give them tuna that’s been canned in water. When they put tuna in oil before they can it, the company making the stuff is adding extra fat that your dog doesn’t need.

Any excess amount of oil can also increase your dog’s risk of developing heart disease or even diabetes. That’s why you’d want to stay away from oil-based products.

Should I Give My Dog Raw Tuna?

Never give your dog raw tuna, but keep in mind that what you think of as raw tuna might not actually be raw tuna. When they can tuna, it goes through a special type of cooking process to kill any microorganisms before they seal up the can.

That’s why you’re able to eat tuna straight out of the can. If you were to get a fresh tuna and scale it yourself, then you need to cook it first before a dog could have it.

Dogs shouldn’t eat human foods made from raw tuna, like traditional Japanese sushi or sashimi, because the combination of raw fish and other ingredients can bother their stomach.

Is Fresh or Canned Tuna Better for Dogs?

Fresh tuna unfortunately may have been exposed to a number of pollutants while it was in the water, thus making canned the better option. That being said, tuna isn’t exactly great for dogs so you’ll want to think twice before you start feeding either to your dog in any great quantity.

Keep in mind that many tuna products that are packed in water will taste fresh without the side-effects of actually being fresh, thus making them a better option for dogs. While tuna might not be the number one thing for your dog, giving them relatively safe fish like this that’s taken from a safe can might actually help to provide rotating proteins for them.

That’s why canned tuna is sometimes given to dogs with nutritional problems.

Can Canned Tuna Upset a Dog’s Stomach?

Canned tuna can definitely upset a dog’s stomach, especially if you have a smaller dog. Tuna that’s packed in oil will usually be worse, since all of that excess oil can potentially give your dog a case of the runs.

Water-packed tuna is usually a bit more mild in this respect, though it’s still rich in fatty acid. While this is great for a human’s heart and one of the reasons that doctors recommend people eat tuna fish, but it can potentially make a dog overweight while giving their belly some serious discomfort.

What Fish Can Dogs Not Eat?

Salmon is the number one edible fish that dogs shouldn’t eat, largely because of the risk of salmonella poisoning. If you’ve never thought about the root of that word before, then you might have just realized that there’s a reason salmon’s name is in it!

Dogs shouldn’t eat the bones or scales of any fish, even ones that are relatively safe like tuna. However, you should be removing these from your meals as well.

Can a Dog With Pancreatitis Eat Tuna?

Dogs who suffer from pancreatitis should never eat tuna or anything else that’s sufficiently fatty like that. There’s too much of a risk that they’d be unable to metabolize it.

Can Tuna Give Dogs Diarrhea?

Dogs can certainly get diarrhea from tuna, and those that aren’t used to it are at a higher risk of developing some sort of gastrointestinal problem from it. Even dogs that seem to have iron stomachs probably shouldn’t have tuna that’s packed in oil, since this can lead to loose stools.

Can I Crack an Egg in My Dogs Tuna?

Cracking an egg into anything your dog gets can be a good idea, but you want to be careful not to get any raw shell into it. Cooking the eggs in a way that doesn’t use oil is usually the best way to deal with the bacteria that live on eggshells.

Granted, the shells themselves can be a supplement for dogs, but you have to cook them carefully and pulverize them before using them this way.

What About the Mercury in Tuna?

Mercury in tuna is a serious problem as a result of pollution settling into the water where these fish live. That’s why you’ll want to limit or restrict the consumption of tuna in any dogs.

Smaller dogs shouldn’t have any tuna at all because of the higher probability that they could develop a form of mercury poisoning.
