Uncovering Truth: Is Tuna Good For Dogs With Kidney Disease

A small amount of tuna can be fed occasionally to dogs that do not have kidney problems. However, when the dog is facing such a disease, this topic “is tuna good for dogs or not with kidney disease” becomes more controversial.

According to a research, one out of every ten dogs may face kidney disease. If phosphorus and protein are added to the diet of such a dog, this disease can increase dangerously. Therefore, it is important that you always feed your dog a low protein diet.

In this blog post, we will cover the nutritional benefits and drawbacks of tuna, as well as why you should not feed tuna to your dog.

Nutritional Benefits: Is Tuna Good For Dogs

Tuna is a fish that like to live in salty water. It also has nutritional benefits for both humans and pets in some cases. Tuna is enriched in nutrients like proteins and minerals containing vitamins A and D and B complex, selenium, Iron, and phosphorus.

All these minerals benefit your dog’s well-being by gaining moderate value according to your dog’s breed, size, and age. Additionally, it is a healthy source of omega-3 fatty acids that are good for your dog’s coat, skin, and cardiovascular system.

Dogs without kidney disease may eat tuna. However, If your pet has kidney disease, you should avoid offering tuna to your pet due to its imbalanced nutritional properties. 

Tuna Nutritional Disadvantages

Tuna absorbs high amounts of toxic mercury material facilitated by water due to industrial activities. Because of it, tuna is a high source of mercury nutrients.

Hence, if your dog consumes a high amount of mercury, it can lead to chronic kidney disease, which is a progressive and irreversible condition.  Additionally, tuna is also high in phosphorous, which is another concern for dogs with kidney disease.

Dogs with kidney disease have difficulty regulating phosphorous levels in the blood, which can lead to the formation of kidney stones and other complications. High phosphorus levels also cause the kidneys to work harder to filter the blood, which can further damage the kidneys.

Can dogs eat tuna fish?

Although dogs can eat tuna in small amounts if needed, but it is not recommended as a regular part of their diet for several reasons:

Nephrotoxicity: Tuna, especially in raw or fresh form, may contain high levels of mercury and other toxins that can harm dogs, particularly those with kidney disease. These toxins can cause nephrotoxicity, damaging the kidneys and leading to further complications.

Nutritional imbalances: Tuna is not considered a balanced diet for dogs, as it is high in protein but low in other essential nutrients such as carbohydrates etc. Feeding a diet high in tuna can lead to nutritional deficiencies over time in dogs.

Allergies: Some dogs may have an allergic reaction to the tuna, which increases the risk of developing symptoms such as itching, hive, and swelling.

Not appropriate for Renal diet: Doctors recommend a diet low in phosphorus and protein for dogs with kidney disease to reduce further stress on the kidneys.

As mentioned above, fish is a product of salt water and contains abundant ingredients like protein and phosphorus, which are harmful to such dogs.

What Kind Of Fish Should I Feed My dog?

When it comes to fish, adding to your dog’s diet plan these kinds of fish you can consider to feed them safely:

Salmon: Salmon is commonly used as food fish and is a good source of Omega 3 fatty acids and protein. It is also rich in vitamins B, including vitamins (B3, B5, B6, and B12) D, E, and selenium.

Although you can feed your dog salmon raw or fresh, but it is recommended to feed your dog boneless and cooked salmon. 

Whitefish: White fish such as cod, haddock, grouper, snapper, and halibut are among the types you can safely feed your dog. This fish also contains health-enhancing minerals such as vitamin B12, vitamin D, selenium, phosphorus, etc.

But while feeding the dog, it is important that whitefish is well-cooked and has no bones. Because a dog can’t eat bones like a human, these can likely cause a problem in his throat.

As mentioned above, you should always give cooked fish to your dog. Raw fish can contain bacteria such as germs that pose a health risk to your dog.


At the end of the topic,” is tuna good for dogs with kidney disease or not?” Tuna can be an excellent source of protein and omega-3 fatty acids for healthy dogs if fed. But its controversial side is the high amount of mercury and phosphorus present in it, due to which it is not fed, especially to dogs with kidney disease.

You should consult your veterinarian if you plan to determine the best diet for your dog’s specific nutritional needs. They will help you create a diet plan that will meet your dog’s nutritional needs and reduce the risk of complications related to kidney disease.
