Best Fish Oil For Dogs – Buying Guide

Some pet owners don’t really like supplements for dogs so they avoid buying them even though they know it can be beneficial. Well, I understand the concern, there are a lot of unreliable brands out there. Fortunately, we are here to help. Check out this buying guide.

Natural EPA & DHA

Docosahexaenoic acid(DHA) and eicosapentaenoic acid(EPA) are Omega-3 fatty acids that have huge health benefits for dogs. That’s why you are buying fish oil, you are looking for these two acids. What matters to you is how these Omega-3 fatty acids are sourced.

Good fish oil for dogs provides DHA and EPA mainly from salmon. These fatty acids are largely found in fish but can be located elsewhere. For dogs, fish are the safest. Fish that contain big doses of these acids are salmon, anchovies, mackerel, sardines.

So, when looking for fish oil for your dog, a product that is made with wild-caught fish is the best. Some products supply EPA and DHA with supplements. Although there’s nothing wrong with that, most experts and people prefer wild-caught fish.

Low In Toxins

Omega-3 fatty acids can be found in much other fish in the seas and the oceans. However, some fish contain toxins that are dangerous to dogs. Fish that are high in mercury and other toxins can’t be used for fish oil for dogs.

Always buy fish oil that uses fish low in toxins. That’s why fish oil from wild-caught Alaskan salmon and anchovies. Avoid any products that say fish oil made with caught fish but don’t name the type of fish.

It’s better to buy fish oil that uses EPA and DHA supplements, instead of an unknown, trusted brand. Although supplements for dogs are not regulated, there are some regulations for toxins.


Fish oil for dogs is not cheap to make. So, some brands will often other ingredients in the fish oil to minimize the cost of manufacturing. Often, brands will add soy derivates, wheat, EPA and DHA supplements, etc… Although this is expected, you should always look for all-natural fish oil.

I recommend products that come in bottles of oil. With chews and tablets, the chances of artificial ingredients are higher. This is not that important though, you should always take a look at what the oil contains. Read the content on the bottle.

Vitamin Supplements

Since you are adding fish oil to your dog’s diet, it’s smart to other vitamin supplements. An easy way to do that is to get a fish oil product that contains other vitamins as well. Vitamin C is really helpful for overall good health.

Vitamin E can help even more with skin inflammation. Some brands also add Calcium, Magnesium, and Zinc to their products. If this is something you want to add to your dog’s diet, consider fish oil for dogs that have additional vitamin supplements.

Health Benefits

Fish oil has several health benefits for dogs. However, most of you will be buying fish oil only for a specific health problem. So, think about what’s more important. For instance, if your dog is shedding, itching, or has skin inflammation, get something specific for skin health.

On the other hand, if your dog has joint problems or arthritis, get something specific for that.
