Shun NagaiFor dog food manufacturers that put canine health first, recipe formulation is one of the most important parts of product development. In recent years, so-called “superfoods,” widely recognized for their benefits in human nutrition, have also gained attention in canine diets.
These ingredients are valued for their high nutritional density and health-supporting properties, and they may help support dogs’ overall condition and longevity. In this article, we introduce 15 superfoods worth considering when developing dog food recipes.
What Is a Superfood for Dogs?
There is no strict scientific definition of a “superfood,” but the term is generally used to describe ingredients rich in antioxidants, dietary fiber, vitamins, and minerals that may positively affect health and immune function.
For example, many superfoods contain high levels of antioxidants, which are believed to help reduce oxidative stress in the body and may contribute to lowering the risk of cancer and other diseases. Oxidative stress occurs when free radicals accumulate excessively in the body and is closely associated with various health problems.
In addition, ingredients such as salmon and coconut oil contain healthy fats that may help support cardiovascular health. High-fiber ingredients like kale may also promote digestion and increase satiety, making them useful in weight management formulas.
What Makes a Good Dog Food?
Commercial complete and balanced dog foods are formulated according to AAFCO or FEDIAF guidelines to provide the nutrients dogs need. So what exactly does a good dog food contain?
Unlike cats, dogs are not obligate carnivores. While meat makes up a significant part of their diet, domestic dogs can also obtain nutrients from grains, fruits, and vegetables. These non-meat ingredients are not simply fillers; they can provide valuable sources of essential vitamins, minerals, and dietary fiber.
A good dog food contains a well-balanced combination of meat, vegetables, grains, and fruits. High-quality dog food includes high-quality versions of these ingredients and helps support overall wellness, including vitality and disease prevention. It can also contribute to healthy teeth, skin, immune function, and digestive health.

Oily Fish
Fatty fish such as herring, salmon, mackerel, sardines, anchovies, and hoki are highly palatable and rich in protein, polyunsaturated fats, and omega-3 fatty acids, which are essential fatty acids. Omega-3s help improve skin and coat condition and may help protect against arthritis, inflammation, and brain aging.
These fish are also rich in vitamins and minerals that are important for bone and joint health, including calcium. In addition, smaller fish such as anchovies and sardines are lower on the food chain, making them more sustainable and generally lower in mercury risk.
Flaxseed
Flaxseed is a highly beneficial superfood for dogs, especially because it is rich in omega-3 fatty acids, particularly alpha-linolenic acid (ALA). These omega-3s have anti-inflammatory properties and may help reduce arthritis and skin inflammation.
Flaxseed also contains dietary fiber, which supports digestion and helps maintain a healthy intestinal environment. In addition, it contains antioxidants and lignans, compounds believed to have antimicrobial and antiviral properties, which may help reduce oxidative stress and support overall health.
Flaxseed can also benefit skin and coat condition by improving coat shine and helping reduce dryness and itching. It may further support cardiovascular health and contribute to stronger immune function.
Chia Seeds
Chia seeds contain protein, dietary fiber, antioxidants, calcium, iron, magnesium, B vitamins, and omega-3 fatty acids.
They may help strengthen the immune system, improve skin and coat quality, and support joint and gut health. Because they may also help regulate blood sugar and satiety, they can be a useful ingredient for weight management formulas.
Hemp Seeds
Hemp seeds are widely used in vegetarian and vegan foods as a protein source containing all essential amino acids. They are rich in minerals such as vitamin E, potassium, magnesium, calcium, iron, and zinc, making them a valuable superfood for skin conditions such as atopy.
One notable feature of hemp seeds is their omega-3 content. Six tablespoons contain 6,703 mg of alpha-linolenic acid (ALA).
Quinoa
Although quinoa is often thought of as a grain, it is actually a seed related to spinach. Quinoa is a complete protein containing all essential amino acids, and it is also rich in powerful antioxidants, dietary fiber, folate, magnesium, iron, and phosphorus. In addition, it has a low glycemic index, meaning it is less likely to cause a sharp rise in blood sugar after meals, which may help reduce the risk of diabetes.
Quinoa contains saponins, compounds that help protect the plant from pests but may irritate the gut. However, the amount of saponin in quinoa is extremely small and is unlikely to cause problems in most cases.
Green-Lipped Mussel
Green-lipped mussels are shellfish native to New Zealand and offer a range of benefits for dogs. They are particularly rich in omega-3 fatty acids such as EPA and DHA, which have anti-inflammatory properties and may help relieve arthritis and joint pain.
They also contain glycosaminoglycans, including glucosamine and chondroitin, which help protect joint cartilage and support mobility. In addition, green-lipped mussels are rich in minerals such as zinc, copper, and manganese, as well as vitamins C and E, which may help strengthen immunity and promote skin and coat health.
They are also an excellent source of high-quality protein, supporting muscle repair and maintenance.
Seaweed (Kelp)
Seaweed is believed to have antioxidant, anti-inflammatory, anti-aging, and anti-cancer properties. It contains protein, soluble dietary fiber, vitamins C and E, a wide range of B vitamins, and minerals such as zinc and copper.
It is also a rare plant-based food containing EPA and DHA, and it provides lesser-known compounds such as sterols and chlorophyll, which may help support metabolism.
Turmeric
Turmeric has been used for centuries for its nutritional and medicinal properties, but more recently it has also been recognized as a superfood for dogs.
The compound curcumin in turmeric is rich in antioxidants and is known for its anti-inflammatory, antiviral, antibacterial, and antifungal properties. Turmeric is commonly included in supplements and is thought to help with cancer prevention, liver support, digestive function, and relief of joint pain.
Sweet Potato
Sweet potatoes are rich in beta-carotene and are said to contain 150% of the antioxidant content found in blueberries. They are also very high in vitamin A, which supports heart health, and contain vitamin C, which helps strengthen the immune system.
Sweet potatoes are an excellent source of dietary fiber and help support healthy digestive function. Adequate fiber intake may also help lower the risk of heart disease and certain types of cancer.
Broccoli
Broccoli is rich in dietary fiber, which helps support healthy digestion. It also contains beneficial nutrients such as potassium, calcium, protein, and vitamin C.
However, cruciferous vegetables like broccoli contain goitrogenic compounds, which may trigger hyperthyroidism. For this reason, broccoli is generally not recommended for animals with thyroid disorders.
Kale and Spinach
These nutrient-dense leafy greens contain many vitamins, including vitamins A, E, and C. Kale is an excellent source of antioxidants and may help support liver detoxification. It also has anti-inflammatory properties. However, dogs with bladder stones or kidney disease may need to avoid consuming it.
Carrots
Carrots are rich in dietary fiber and contain beta-carotene, which helps support immunity, eye health, and improvements in coat and skin condition. They also provide carotenoids, dietary fiber, vitamins C and K, and are high in potassium. In addition, they contain magnesium, manganese, B vitamins, and phosphorus, which is necessary for energy production.
Watermelon
Watermelon is a nutrient-rich superfood containing antioxidants, amino acids, vitamins A, B, and C, as well as potassium and magnesium.
Berries
Berries are rich in antioxidants. Antioxidants help neutralize free radicals in the body and protect cells. This may help protect dogs from age-related decline and environmental stressors such as UV exposure and chemicals. Their antioxidant activity may also support the immune system and aid in disease prevention and recovery.
Coconut Oil
Coconut oil is believed to offer a variety of benefits, including support for digestive and immune function. Many of these benefits are attributed to the medium-chain fatty acids it contains. These fatty acids are thought to promote weight loss, improve energy metabolism, and may even help reduce seizures and cognitive decline.
