It’s not just humans that can benefit from fish oils, they can also be used to help put a spring back into your dog’s step. Packed with essential fatty acids, fish oil has many anti-inflammatory properties and contain the omega 3s, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) which are powerhouses when it comes to your pet’s health. Added to your canine’s diet, fish oils can improve the condition of your dog’s coat and skin as well as boost their joint, heart, eye, brain health and all-round wellbeing.
The best fish oils are derived from oily fish such as mackerel, tuna, salmon, herring and anchovies and, as your pup cannot produce many of the essential omega-3s themselves, adding extra to their diet could well work wonders. But with so many to choose from, it can be a bit of a chore to fish out the right supplement for your dog. We trawl through some of the most popular brands on the market to help you choose the best fish oil for dogs to give your pooch an extra health boost.

Best Fish Oil For Dogs Buying Guide & FAQ
What is a Fish Oil Supplement?
Fish oil is one of the most consumed dietary supplements, for both humans and domestic pets and is sourced from oily fish, such as mackerel, salmon, herring and cod liver. Fish oil is one of the best sources of omega-3 fatty acids, which are essential for good health, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), although you can also obtain some omega-3s from plant sources.
Omega-3 fatty acids – especially EPA and DHA – are anti-inflammatories and have many health benefits and are believed to help support brain, heart and eye health as well as help to protect against a number of diseases. If you or your pet are not getting enough omega 3 fatty acids from your daily diet, then a supplement is a good way to go. Made from fish oil extracted from the fish tissue, supplements can come in either gel capsule or liquid form. Good quality fish oil also contains vitamins A and D.

- Can help to treat arthritis
Fish oils are regularly used as a therapeutic treatment for arthritis in dogs and have been shown to ease joint stiffness and mobility issues. The anti-inflammatory properties of fish oil can also be beneficial for older dogs in general and can help to put a bit of a spring back into their step.
- Helps with brain health
Fish oils can be beneficial for older dogs to help boost and maintain their cognitive function. It is thought that the fatty acid DHA in particular, can not only improve cognitive abilities but also potentially slow down inevitable deterioration in how your ageing canine’s brain functions.
- Supports heart and eye health
Not only can fish oils help to support your pet’s cardiovascular health but it is thought to help in weight management, which is often a factor when it comes to chronic heart issues in canines. When it comes to their eye health, the DHA fatty acids present in fish oil can also help to maintain the healthy levels of natural DHA present in your dog’s retina and support their overall eye function.

Fish oil is often used as a therapeutic treatment for dogs with kidney disease, particularly glomerular disease which causes excessive protein loss. In this condition, fish oil has been shown to slow down the progression of chronic kidney disease and can help to protect your dog’s overall kidney health.
Does My Dog Need Fish Oil?
As your pooch cannot naturally produce its own essential fatty acids (in particular, EPA and DHA) then to obtain all the health benefits, they need to obtain enough from their diet. However, this is not always as easy as it sounds, especially if your pet is eating a lot of high-grain foods. A balanced diet for your pet is always the first route when it comes to ensuring they are getting all the nutrients they need. But if you suspect your pet is missing out on omega-3s or they have a few health niggles which could benefit from a fatty acid boost then omega-3 supplementation in the form of a fish oil could be beneficial. If you are in any doubt as to whether to give your dog a fish oil supplement, speak to your veterinary professional for advice.
How to Pick a Good Fish Oil Supplement for Your Dog
With a wide selection of fish oil supplements for dogs on the market, it is essential you do your homework so that you pick the best product for your pet. To get the best fish oil for dogs, you need to check out the following on the packet:
- What type of fish oil it is: There are three main types: natural triglyceride oil, which is the easiest to absorb but isn’t purified and so could contain contaminants; ethyl ester oil, which has been distilled and concentrated to remove impurities so is considered semi-natural; and synthetic triglyceride oil, which is not a natural source, and is least easily absorbed.
- Go wild: Always choose a supplement that is sourced from wild caught fish as farmed fish can have very high levels of heavy metals and toxins.
- Look for the quality control: You need to be sure the source of the fish oil has been treated to a high standard and is safe for your pet. FDA-registered, National Animal Supplementation Council (NASC) certification, country of origin or a recommendation from your vet are all good places to start.
- Check the EPA and DHA levels: Going for the highest levels of DHA may not always be the best combination for your pet, unless brain and eye health is your priority as DHA can be easily be stored in the body. EPA, however, cannot be stored and so supplementing at a good level is essential.
