In the quest to provide our canine companions with a varied and nutritious diet, many pet owners in the UK often explore the option of incorporating fish into their dog’s meal plans. Mackerel, known for its high omega-3 content, emerges as a popular choice. However, when it comes to serving mackerel in tomato sauce, there are several considerations to bear in mind.


Before we delve into the specifics, it’s crucial to acknowledge that individual dogs have unique dietary needs and sensitivities. Therefore, always consult a qualified veterinarian or a dog nutritional expert before introducing new foods into your dog’s diet. This article aims to provide general guidance and should not replace professional advice.

Nutritional Benefits of Mackerel

Mackerel is a nutritious fish that offers several health benefits for dogs. It is rich in omega-3 fatty acids, which can support skin and coat health, reduce inflammation, and contribute to overall heart health. Mackerel is also a good source of protein and essential vitamins and minerals.

Considerations for Tomato Sauce

While mackerel itself is beneficial, the tomato sauce it’s often served in can pose risks. Tomatoes belong to the nightshade family, and while the ripe fruit is generally considered safe for dogs, the green parts of the plant are toxic. Furthermore, commercial tomato sauces often contain added sugars, salt, onions, garlic, and other ingredients that could be harmful to dogs. High levels of sodium, for instance, can lead to dehydration and salt poisoning, while onions and garlic are toxic to dogs.

Preparing Mackerel for Dogs

If you’re considering adding mackerel to your dog’s diet, opting for fresh or canned mackerel in water or brine (with no added salt) is preferable. It’s important to ensure the fish is cooked thoroughly to kill any parasites and deboned carefully to prevent choking hazards or internal injuries.

Alternative Options

For those still interested in incorporating fish into their dog’s diet without the risks associated with tomato sauce, there are safer alternatives. Fish such as salmon, sardines, and tuna (in moderation) can also offer similar nutritional benefits when prepared safely.


Mackerel can be a healthy addition to your dog’s diet, provided it’s served appropriately. However, when it comes to mackerel in tomato sauce, the potential risks outweigh the benefits. Always prioritize your pet’s safety and well-being by choosing plain, safely prepared fish and by consulting with a professional for tailored dietary advice.

Remember, while exploring new foods can be a fun way to enrich your dog’s diet, it’s essential to proceed with caution and informed guidance. Your furry friend relies on you to make the best choices for their health and happiness.
