Can Dogs Eat Tuna? (3 Pros and Cons)


can dogs eat tuna

People who enjoy eating sushi or getting supplements for your workout know that tuna is a great ingredient to add to your diet, so can we do the same for our dogs as well? To answer both sides of this argument, I have picked out several positive and negative points of feeding tuna to your dog.


Benefits of Feeding Tuna to Your Dog

To begin the argument for the positive side, several major nutrients that are present in tuna are listed down below, and the health benefits of each nutrient will be all listed in the end to wrap up our points. Let’s begin!

  • High-Quality Protein
  • Omega-3 Fatty Acids
  • Selenium
  • Vitamin D

The benefits of protein will be covered in our first section, but the rest will be covered in our third section that argues for the positive side. Make sure to read the points in the drawback section before making your final choice!


1. High Amounts of Protein

Out of 100 grams, nearly a quarter of that 100 grams is made up of protein, which is a good-sized amount. This is great news for your canine companion since protein and fats should consist of nearly 50% of his diet, and tuna provides both at the same time!


2. Great Source of Fats

In addition to protein, tuna is a great source of fats, but you need to be careful when it comes to canned tuna. They might contain excess sodium, which is not good for your dog’s health, but other than that, tuna is a great source of both fats and protein.


3. Countless Health Benefits

Instead of giving omega-3 pills, give your dog some tuna, which is rich in omega-3 fatty acids. Why is omega-3 so popular these days? Because omega-3 acid is vital for cardiovascular health, brain function, and growth development, tuna is a great addition for any dog or human alike.


Drawbacks of Tuna for Dogs

For many dog owners out there, you probably don’t go out and catch raw tuna for your dog, but rather you go to the store and buy some canned tuna for cheap. For either case, you still need to read the words of caution, so please stick around till the end!


1. High Levels of Mercury

Mercury is a toxic substance for most living things, so your dog isn’t an exception to this rule either. Since big-sized tunas are caught through the net, it takes many years on the sea for that tuna to grow to its full-size. Due to pollution on the seas, mercury starts to accumulate on the tuna.

Basically, some levels of mercury will accumulate, so don’t feed large amounts of tuna to your dog. Always make sure to give food in moderate amounts, and don’t feed in excess!


2. Needs to Be Washed

With any canned products, you have to watch out for substances that are added during the processing stage. After opening the can, it is best to wash out any additives or excess sodium with water. In the list down below, I have listed three simple steps that you can follow.

  • Open the Can
  • Wash the Tuna Thoroughly
  • Let It Out to Dry Before Feeding

During the washing process, fats and oils might get removed, so if you want to keep all the nutrients regardless of whether they are good or bad, you can just use the tuna straight out of the can. 


3. Can’t Use Raw Tuna

If you ever had sushi, you probably have heard the dangers of raw fish, regardless of their type. To remove any parasites or harmful bacteria, it is best to use cooked tuna rather than feeding it raw. To avoid any unnecessary dangers, don’t use raw tuna!

What Are Some Other Healthy Alternatives to Tuna?

Tuna is a great healthy option just by itself, but to add more options, I have to say that any type of meat is a great source of protein. Even though they might enjoy it, I personally don’t recommend giving raw meat to your dog since we can’t guarantee their safety. 

You might say that dogs in the wild ate raw meat for centuries, but we don’t really do health checkups on dogs in the wild (In short, we don’t really know). If you really do want to give raw meat to your dog, be sure to check the quality of the meat, and please keep in mind this one thing. 

If your dog develops a taste for raw meat, he might not eat any commercial dog-food that you might give to your dog, which will mean that your food cost will go up. If you want your financial state to stay the same, use dog-foods that are meat flavored!


How Can I Prepare Tuna for My Dog?

In most cases, we will be using canned tuna for this illustration, and if that is your situation, the easiest way is to dump that tuna inside your dog’s food bowl. If you want to make it just a tad bit better, you can wash the canned tuna and then feed it to your dog. 

For dog owners who are into homemade dog food, you can mix the canned tuna with a bit of greens and rice to get the needed carbs and fiber. Last but not least, there will be some who buy raw tuna for their family to cook, and if that is you, be sure to cook the tuna thoroughly before giving it to your dog!


Is It Ideal for My Dog to Eat Tuna?

After considering the drawbacks and the benefits, I personally think tuna is a great addition to any dog’s diet. This fish is a great source for protein and fats, and it even provides a small number of carbs on the side.
