Top 5 Fish Oil for Dogs

Latest Update: August 06, 2019

While it is common to associate fish with the diet of cats, fish oil is something which if added to the diet of dogs will give them many healthy benefits. There are different schools of thoughts on whether giving fish oil to dogs is safe or not.

Take it from me, when it comes to provide the dogs with the right food to keep it healthy and give it a longer life, there is nothing as good as adding fish oil to the dog’s diet.

You must have heard about the positive effects of fish oil on humans. Your canine companion also gets benefitted by fish oil just the way you do. The huge deposits of Omega-3 fatty acids in fish oils not only improves the health of the heart and skin, or improve the shine of the coat, it brings on several other advantage in favor of the pooch’s health.

6. Conclusion


Honestly, there are so many advantages of fish oil supplements, if they all would have to be written, the list would become a never-ending one. The major ones are as mentioned below.

  • Inflammation of heart, kidneys, liver, skin or joints (that causes arthritis) can be reduced with the help of the anti-inflammatory properties of EPA, one of the two Omega-3 fatty acids for dogs.
  • Improves skin condition by adding moisture, thereby reducing shedding, dandruffs and itchy skin in the poor animal
  • There are proven advantages of this oil for dog shedding. It is known to reduce the shedding manifolds along with promoting a shiny and healthier coat.
  • As like human babies, puppies also get hugely benefitted by DHA, the second of the two Omega-3 fatty acids. It is known to develop the eyes and brain of little pups.
  • Fish oils are also a potent source of renewing the energy levels and increase the stamina of the dogs
  • Fish oil also slows down the growth of cancer in pooches.

How to Choose the Best

You will find Omega 3 for dogs with allergies, liquid oil, fish oil capsules for dogs at Amazon! The obvious question is that how would you select the best one for your beloved pet. The answer is simple. Choose the one which has the highest concentration of EPA and DHA.

It oil is available from many sources, not all of which have the same concentration of EPA and DHA. While Krill, Sardine, Mackerel or Herrings have a higher percentage of EPA than DHA, the DHA content of Salmon, Pollock or Cod Liver oils beat the amount of EPA. As long as there is a minimum of 6-8% of EPA and DHA in particular fish oil, it is good to be considered for your pooch.

Another thing to look out for while buying the best oil is whether the oil is coming from farmed fishes or wild caught ones. While oil from wild caught fishes is what I recommend, not every manufacturer produces that.

If the oil is derived from wild caught fishes, usually they mention it as a highlight. If nothing is mentioned on the label, you will have to assume that it is from farmed fishes only. It is not that bad either, but nothing can beat the quality of fish oils coming from the wild caught ones.


As I mentioned already, it is good to have a right balance of EPA and DHA in the fish oil that are available for dogs. After reviewing a good number of commercial fish oil supplements, I have narrowed the list to few products which I think would be good for the overall well-being of your canine friend.

However, if your dog is allergic to any of the components of these fish oil supplements, do consult your vet before administering the product to the dog.

Frequently Asked Questions

How much omega 3 for dogs per day?

Although you may get conflicting opinions on this, but the ideal amount of Omega-3 for dogs per day should be around 1500-2000 mg. A simple way to determine the dosage is to multiply the weight of dog in pounds by 20 to get the required dosage of EPA.
