What To Look For In The Best Canine Fish Oil

Once you understand why giving your dog fish oil is a great idea, you need to start weeding through the hundreds of products on the market. To make the selection process easier, consider these factors that contribute to the best products.

  • Fish Oil Source

Take the time to look at where the fish oil itself is coming from. The best fish oil for dogs will indicate this right on the label or even in the name in a phrase like “fresh Alaskan salmon” or “New Zealand fish.” The exact location of the fish is not incredibly important, but the conditions they are raised in are. The top oils will come from fish which were raised in a natural environment without any contaminants in the water. This way, you can trust that they won’t contain mercury or other similar elements.

Be wary of fish oil that comes from fish raised in factory farms where they are overcrowded, polluted, and fed things like dyes and antibiotics. This can result in higher contamination levels in the oil itself, putting your dog at risk.

  • Fatty Acids And Nutrients

The vast majority of fish oils for dogs will market their quantities of omega-3 and omega-6 fatty acids. These are the most important nutrients to look for in fish oil as they are typically the reason you are giving your pooch these oils in the first place. That being said, many products will have additional vitamins, such as Vitamin E to provide your pooch with further benefits. It can be worth it to spend a bit extra on fish oil with these vitamins, especially if they are from high-quality sources.

  • Veterinarian Approval

Although not all fish oil supplements will be veterinarian approved, the best options will. This is a great way to ensure that the product is safe for dogs to use and that it has been medically tested. If a product isn’t explicitly listed as veterinarian approved, do some quick research to see if any vets have written reviews about it. At the very least, check to ensure a particular product doesn’t have any negative reviews from vets.

  • Liquid Or Capsule

Looking at the various fish oil supplements for dogs, you will notice that some come in liquids while others are capsules. The most popular options are liquids and this is no mistake as most pet owners find it easier to convince their pooches to drink a liquid. It comes down to personal preference, but it is typically simple to just mix the liquid fish oil with your dog’s favorite food. By comparison, capsules typically require some sort of trick to get your dog to swallow, making them more complicated to give. It is, however, a matter of personal preference and some pet owners find it simpler to just stick a fish oil capsule in a hot dog or other treat and give it to their canine.

  • Taste

If you want to be successful in giving your dog fish oil, you need to buy a product that he will enjoy the taste of. Most dogs like the flavor of fish oil, but it is still a good idea to read some reviews and make sure people say that their pooches enjoy the taste. In the ideal situation, your dog will love the flavor of the oil so much that he will see it as a treat that he looks forward to.

  • Concentration And Clear Dosage

Fish oil for dogs can come in a range of concentrations so you want to make sure you choose the correct one for your pooch. To actually get the benefits of fish oil, your pup will need to take a large enough dose, which is why you want to make sure you understand the dosage instructions. The best fish oils will give some sort of varying dosage based on weight, whether it is a different dose for various weight ranges or a quick calculation you should do based on your furry friend’s weight. You want to avoid giving your dog too little where you don’t see effects but also avoid giving too large of a dose as this can cause other issues, such as increased bleeding or making inflammation worse instead of better.

Experts typically suggest you give your dog a dose of no more than about 100 or 150 mg of EPA and DHA for every 10 pounds of his bodyweight. If your dog has health problems, you can increase this to 300 mg for every 10 pounds.

  • Lack Of Mercury

Anytime you are eating fish or giving it to your animal, you need to be sure that there are no contaminants such as mercury. This will rarely be the case, but is still a concern, especially among fish oils for dogs that have unreasonable low price tags. In most cases, forms that have higher concentrations will have fewer contaminants as well.


Now that you know which products are the best fish oil for dogs, it should be easy to pick. Just select one of the supplements mentioned above and start watching your canine companion get healthier by the day.
