Comparing Sardine and Salmon Omega Supplements for Dogs


When it comes to providing our furry companions with optimal health, omega-3 fatty acids are a must-have in their diet. Two popular sources of these essential nutrients are sardine and salmon-based omega supplements. While both options offer numerous benefits, understanding their differences can help you make an informed decision about which supplement is best for your dog. In this blog post, we'll explore the unique advantages of sardine-based omega supplements in contrast to salmon-based ones, all backed by scientific evidence.

Richer in EPA and DHA

Both sardine and salmon are excellent sources of omega-3 fatty acids, but sardines have the edge when it comes to EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) content. EPA and DHA are the two most biologically active forms of omega-3s, known for their anti-inflammatory properties and overall health benefits (Kris-Etherton et al., 2018). Sardine-based supplements tend to contain higher concentrations of these vital fatty acids, making them a powerful choice for promoting joint health, reducing inflammation, and supporting a shiny coat.

Lower Risk of Contaminants

Sardines are relatively low on the food chain, meaning they have less exposure to potential contaminants like heavy metals and toxins that can accumulate in fish. On the other hand, salmon are higher on the food chain, and their larger size can lead to an increased risk of accumulating certain pollutants (Carrington et al., 2020). Opting for a sardine-based omega supplement may thus offer a safer choice, reducing the likelihood of exposing your beloved pet to harmful substances.

More Environmentally Sustainable

Choosing sardine-based omega supplements can also have a positive impact on the environment. Sardines are a small, fast-growing fish with a high reproductive rate, making them a more sustainable option compared to some salmon species, which can be overfished and face population decline (Hilborn et al., 2020). By opting for sardine-based supplements, you can support more responsible fishing practices and contribute to better marine ecosystem preservation.

Irresistible Taste for Dogs

Palatability is an essential factor when introducing supplements into your dog's diet. Many dogs find the taste of sardines more appealing compared to salmon, which can be beneficial when trying to encourage a picky eater to consume their omega-3 supplement. The added convenience of sardine-based omega supplements being more appetising to dogs can make it easier for pet owners to maintain a consistent supplementation routine.


When it comes to choosing between sardine-based and salmon-based omega supplements for your dog, both options offer valuable health benefits. However, sardine-based supplements have a slight advantage in terms of higher EPA and DHA concentrations, lower risk of contaminants, environmental sustainability, and canine palatability. These factors make sardine-based omega supplements a compelling choice to enhance your dog's overall well-being and support their joint, skin, and cardiovascular health. Before introducing any new supplement to your dog's diet, it is a good idea to consult with your veterinarian. They can assess your pet's specific needs and health condition to determine the most appropriate omega-3 supplement for your furry companion.
