The 5 Best Omega-3 Supplements for Dogs

Is there any doubt how much we love our dogs, or that we’d do anything for them? All dogs are special, but some have special needs – especially older dogs or pooches with pre-existing genetic conditions. One of the most popular supplements for dogs is Omega-3, a family of the family acids DHA, EPA and ALA. These fatty acids are advertised to assist with liver function, skin conditions, arthritis, lymphoma, heart disease, allergies, cognitive function and more. If you think your dog might benefit from an Omega-3 supplement, talk to your veterinarian, then make sure you’re choosing the highest-quality supplements on the market. We’re not vets, but we know a thing or two (or five) about quality, so here’s what we’ve found to be the best five Omega-3 supplements for dogs.

Best Liquid Supplement

Nutritionists agree that one of the most powerful sources of Omega-3 fatty acids is fresh salmon. Of course, not everyone can grill-up a nice piece of salmon for their dog every day, so Zesty Paws has a more economical solution in their Pure Liquid Salmon Oil. A great alternative to soft chews or capsules, each dose has a high amount of DHA and EPA, helping your dog maintain a soft and shiny coat while protecting his immune system and joint functions. Made with wild Alaskan salmon, Zesty Paws tastes great and mixes right into your dog’s daily food. We don’t usually have two products from the same company on our short list of five, so it says a lot about Zesty Paws that these supplements are in our top two!

Pros:

  • Made in the USA
  • Stores at room temperature
  • No unpleasant smell

Cons:

  • Oils can lose effectiveness after 2 weeks
  • Dispenser can get messy

Older dogs especially may require more than one supplement. Glucosamine and Pantothenic Acid are two other popular supplements suggested for bone and hip health for older dogs. If your pet is already taking other supplements for his health and you want to integrate Omega-3 into his diet, we suggest Vetflix 10-In-1 Pet Vitamins. As the name suggests, each dropper-full contains ten different vitamins and minerals, including Omega-3, B12, B6, Biotin, Glucosamine and many others. And since it easily mixes in with your pet’s food, you don’t have to give your dog multiple pills or treats to provide him with all the supplements he needs.

Pros:

  • No additives or GMOs
  • Made in an FDA and GMP-registered facility
  • 100% Satisfaction Guarantee

Cons:

  • Taste is polarizing – your dog may not enjoy

Dogs can certainly be as finicky as their owners – if not more so. Maybe they don’t like the smell of their fish oil supplement? Maybe the dog treat supplement contains ingredients you don’t want to feed your pet? Maybe you’re one of the lucky few whose Pit Bull prefers pills? Whatever your case may be, if you or your dog prefer the convenience of a simple pill for your Omega-3 supplement, Vetoquinal has you covered with one of the highest-quality products on the market. Their triglyceride fish oil contains all the fatty acids your dog needs, and is guaranteed to be free of mercury, BPAs and other toxins that may be present in wild-caught fish.

Pros:

  • Only supplement with USP Ingredient Verification
  • Also contains vitamins E, A and C
  • Available in size for large and small dogs

Cons:

  • Purity certification available on request

Frequently Asked Questions

How do I know if my dog needs supplements?

Ask your veterinarian. Most dog food is formulated to have all the nutritional needs your dog requires, since your pet typically eats the same thing day in and day out. As such, the vitamin and mineral balance your dog needs is already in his daily diet. Adding supplemental vitamins to this diet could cause toxicity if those vitamins are not required. Talk to your vet to determine if your dog has special needs that require supplements.

Is there any science to back-up the idea that dogs need Omega-3 supplements?

Yes. According to a 2016 study by Tufts University, dogs with heart disease stand to benefit from the fatty acids found in Omega-3, as they help provide protection against arrhythmia (irregular heart rhythm) and reduce inflammation. The dose of Omega-3 recommended by the study for dogs with heart disease is 40 mg/kg eicosapentaenoic acid (EPA) with 25 mg/kg docosahexaenoic acid (DHA) per day. That said, do remember that most statements of any vitamin’s efficacy have not been verified by the FDA.

How do I know if I should get chewables, pills or drops?

This is where you’ll have to practice the time-honored practice of trial and error. Like humans, all dogs are different, and their tastes and preferences will vary. Unless your veterinarian tells you otherwise (and insists on one formula or brand over another), you’ll need to take your best guess and try different products until you find the one your dog will eat (without trying to eat you).
