The Best Omega-3 Supplements for Dogs in 2022

A healthy diet is essential to a healthy dog. In most cases, this means feeding your pet dog food, which has been carefully formulated to give the nutrition they need to live an active, healthy life. But there are some cases where dog food just doesn’t cut it.

Omega-3 supplements can balance out your dog’s diet while improving skin & fur health and promoting cardiovascular wellness. We’ve compiled a handy list of our top choices for the best omega-3 for dogs, along with a guide to help you understand what omega-3 is and how it can help your dog.

What is Omega-3?

Omega-3 is a kind of fatty acid. The body does not naturally produce Omega-3, and it therefore must be obtained through the diet. This type of fat is polyunsaturated, or the “good” kind of fat. Omega-3 is one of many fatty acids that mammals need in order to live.

There are 3 kinds of omega-3. There is EPA and DHA, which are most commonly found in fish, and there is ALA, which is found in plants. Fish oil supplements focus on EPA and DHA omega-3. ALA omega-3 is found in flaxseed oils.

What are the benefits of Omega-3 for dogs?

There are many claimed benefits of omega-3, but not all have yet been proven.

The most common claim is that omega-3 can reduce risk of cardiovascular disease. This is partially true. Studies show that regular consumption of seafood is linked to a lower incidence rate of heart disease. These studies do not prove that EPA and DHA omega-3 fatty acids are responsible for this boost.

Omega-3 may relieve symptoms of rheumatoid arthritis, which is an autoimmune disease where the immune system attacks healthy cells by mistake.

There is another type of omega, called omega-6. Consumption of omega-3 helps to balance out omega-6, which is quite common in dog food and other processed foods. Dogs often get too much omega-6 and too little omega-3. Omega-3 supplements can balance your dog’s diet. 

How to choose the omega-3 that’s right for your dog

There are many kinds of omega-3 supplements for dogs. Most are fish oils, which contain EPA and DHA. There are some flaxseed oils that focus on providing APA omega-3.

It’s important to avoid manufactured formulation omega 3. Rather, you should choose a natural triglyceride oil rather than the ethyl ester formulation. Put plainly, natural salmon oil is best.

Otherwise, you want to find a supplement that your dog enjoys. Many supplements come as soft chews, which can be more appetizing than pills but can sometimes have a funky smell. Each pet is different, and it may take a little trial and error to find that omega-3 that best suits your furry friend.

Best Liquid

Deley Naturals Wild Caught Fish Oil for Dogs


Unlike chews, this liquid omega-3 supplement gets mixed into your dog’s food at mealtime for maximum ease. Loaded with EPA and DHA fatty acids, this fish oil will leave your dog’s fur looking radiant and can promote heart and joint health. Deley Naturals carefully manufactures their omega-3 fish oil from small fish in the North Atlantic, and they distill the oil to remove any heavy metals that are commonly found in salmon oil.

Bottles come in 4oz, 16oz, or 32oz sizes. One pump of fish oil is recommended for every 25 pounds of weight.

Best Gels

Nordic Naturals Omega-3 Soft Gels for Dogs


Gels make another great no-spill option for serving fish oil to your pet. Nordic Naturals’ fish oil for pets is free GMOs, gluten, and dairy products, and there are no artificial colors, flavors, or preservatives, meaning you can be sure your pet is getting a safe, natural supplement.

And unlike other brands, Nordic Naturals focus on sustainability. Their fish oils are certified by Friends of the Sea and are made in a zero-waste facility. Score!

For bigger dogs, the gels may be added to dog food. For small dogs who cannot swallow the gels, you may puncture the gel and apply it onto food or serve it by itself. The recommended dosage is one capsule for every 20 pounds of weight, daily.

Best Flaxseed Oil

Wholistic Pet Organics Flaxseed Oil


Flaxseed is another option for adding omega-3 fatty acids to your dog’s diet without those fishy smells. Unlike fish oil, flaxseed oils contain ALA fatty acids, which can provide the same boosts as EPA and DHA. The downside is that the ALA omega-3 has to first be converted into EPA and DHA in order to provide those benefits. This means that ALA may not be as effective as other types of omega-3.

Wholistic Pet Organics is our favorite flaxseed oil for dogs. This oil has omega-3, omega-6, and omega-9. There are no artificial ingredients, no GMOs, and no fillers added. One container is 16 oz. The recommended dose is ½ teaspoon to 1½ teaspoons, so this oil is sure to last you a long time.
