Buyer’s Guide to the Top Rated Best Fish Oil for Dogs

A lot of people know about the benefits of fish oil for us and the extensive research put into it, but can be surprised when thinking about how it can help dogs. It’s not as well known, but dogs can get a lot out of fish oil. Having a diet that has the right fats (such as fish oil) can help their appearance and their health.

The reasoning is simple: Dogs and cats would get some amount of fish oil in their natural diets while in the wild. Just as they enjoy the benefits from natural animal fat from prey on land, food caught in the water can also provide some great nutritional elements. That’s why you may want to consider adding fish oil supplements to your dog’s diet if you haven’t already. They could be missing out on some of the very best nutrients necessary to maintain a happier, fuller, and longer life.

In this buyer’s guide, we will cover everything you want to know about fish oil for dogs and we give you our top 5 recommendations of the best fish oil supplement products available.

Top 4 Benefits of Fish Oil for Dogs

Healthier skin and fur. Fish oil in your dog’s diet can improve their skin through the Omega-3s in it which can help give your dog a naturally shinier coat as well as improving their skin.

Reduced shedding, inflammation, and dry skin. Fish oil adds moisture to the dog’s skin, resulting in the aforementioned improvement to appearance, but it can also reduce inflammation at the cellular level, which in turn can reduce the amount of fur that a pet sheds.

Improved stamina and immune system. As a benefit of reduction of inflammation, your dog’s immune system will have more energy to devote to fighting off other diseases, such as viruses and bacteria, as well as more energy to run, play, and generally do what dogs love to do.

Improved joint health. Reduced inflammation can also mean a reduction in the amount of discomfort that older dogs can feel around joints, which can experience the very same problems that aging humans can. Reduction in joint inflammation means that your dog will be more inclined to stay active, happy, and healthy, encouraging a stronger immune system and cardiovascular health.

Any Side Effects Possible with Fish Oil Supplements?

Gastrointestinal distress. This can be caused by introducing too much fish oil into your dog’s diet at one time. This can be noticeable by changes in bowel movements or flatulence levels along with general discomfort. It’s always best to speak with a veterinarian, and figure out the right rate of introduction of fish oil supplements to your pet. Work your way up to the recommended dosage.

Reduction in clotting. Fish oil, by its very nature, is a slippery substance. While it owes much of its benefit to that fact, it can also slow down clotting by making it more difficult for platelets to stick together. If your dog has a history of getting scrapes and cuts while playing in the outdoors, or when roughhousing with other dogs, then you may want to ask your vet about the right levels of fish oil to provide your pet. It’s VERY important to not give your dog fish oil if they are on any blood thinning medications.

Possible interaction with other anti-inflammatory medication. If your pet is already prescribed with an anti-inflammatory, please consult your vet before giving it fish oil. There may be a negative interaction.

How to Calculate the Fish Oil Dosage

  • Under 30 lbs: Consult a vet. Amount will likely be under 1,000 mg of fish oil.
  • 30-60 lbs: 1000 mg is recommended.
  • 60-90 lbs: 2000 mg is recommended.
  • 90-110 lbs: 3000 mg is recommended.
  • 110-140 lbs: 4000 mg is recommended.

By now, you’ve likely noticed a pattern: For every 30 pounds of body weight, it’s recommended that you give a dog 1000 mg of a fish oil supplement, which contains 300 mg of EPA/DHA.

As always, it’s best to consult a vet if your dog has serious health concerns, as the vet may recommend an increased amount of fish oil to combat potential issues. Even if your dog doesn’t have serious health issues, remember that this isn’t set in stone and talking to your vet about dosage specific to your dog is ideal.

Special Note About Vitamin E and Fish Oil

Increased intake of fish oil can also mean a decrease in vitamin E, which dogs also need. When choosing the right supplement, you may want to search for brands that include vitamin E options, or purchase vitamin E supplements for dogs separately.

Vitamin E is important in:

  • Maintaining eye health.
  • Supporting a healthy immune system.
  • Reducing muscle wastage and degeneration.
  • Promoting greater fertility in dogs.

A good rule of thumb to follow is the more fish oil your dog takes, the more vitamin E they will need. The exact calculations for vitamin E necessary are a bit more precise than our general fish oil dosage guide, but understand that higher quality fish oils actually reduce the amount of vitamin E required, while lower quality fish oils increase that amount. That’s why it’s always best to go with the healthiest, most effective fish oil specifically formulated for dog health.

Questions About Fish Oil From Other Dog Owners

Where to buy fish oil for dogs?

There are a number of different places that you can buy fish oil supplements for your dog, including local pet stores. You will find that most pet supply stores carry these supplements, but you can also get them online.

You will be able to give your dog the same fish oil supplements that humans use. You will find that the average fish oil capsule is anywhere from 1000 to 1500 milligrams, and one capsule is perfectly adequate for a dog that weighs 20 pounds or more. If you have a dog that weighs less than 20 pounds, you will give it a lower dosage. Dogs with allergies may need a higher dosage, but it’s important that you consult with your veterinarian before giving your pet more than 1500 mg of fish oil.

How often do I give my dog fish oil?

You can most likely give your dog a single fish oil supplement every day, though you should consult your veterinarian if you are unsure. Many of the specific supplements will have dosage instructions on the packaging.

Why use fish oil for dogs?

There are a number of benefits associated with giving fish oil to your dog, including the fact that it can give them a healthier, nicer looking coat of fur. These supplements can also decrease inflammation for dogs that suffer from arthritis, making them more comfortable and happier overall. Giving fish oil supplements to your dog on a regular basis can also improve their immune system, which helps with fighting off disease. Reduced joint discomfort, protection against auto immune diseases, and decreased shedding are a few other primary benefits that your dog will enjoy as a result of taking fish oil supplements each day.

What’s the difference between salmon oil, krill oil, and regular fish oil?

While it is true that salmon and krill oil can provide dogs with the highly beneficial omega-3 fatty acids DHA and EPA, there are some differences you should be aware of. Krill oil is derived from small crustaceans as opposed to fatty fish, and usually contains a greater amount of EPA. And unlike regular fish oil, the omega-3 fatty acids in krill contain the antioxidant known as astaxanthin. Fish oil does, however, have a significantly longer life than krill oil, lasting around 48-72 hours before the oxidation and decomposition process begins. Salmon oil is derived entirely from salmon, whereas fish oil is derived from trout, salmon, herring, sardines, albacore tuna, and other types of fish.

1. Grizzly Salmon Oil All-Natural Dog Food Supplement

Grizzly Salmon Oil

Available in convenient pump-bottle dispensers in various ounce containers, Grizzly Salmon Oil only uses 100% pure oil from wild, Alaskan salmon. This supplement contains 15+ varieties of various fatty acids, along with the Omega 3, Omega 6, and Arachondic fatty acid groups that you’d want to get from a fish oil supplement.

The convenience of the pump bottle dispenser cannot be understated: Being able to refrigerate and store these bottles allows dog owners to quickly and easily add just the right amount of fish oil to meals. With the pump, you also have much less of a mess to deal with during meal time. Each pump of the bottle will contain roughly the 1000mg dosage that you would want per 30 pounds for your dog, which also makes measurement a breeze.

It goes without saying that the naturally sourced fish oil why this product makes the list. Other fish oil dog supplements may source their product from questionable fish farms, including those which have levels of mercury in them. Grizzly Salmon’s Oil is only sourced from wild caught salmon, and has been thoroughly tested for safety and quality standards.

2. TerraMax Pro Omega 3 Fish Oil

TerraMax Pro Omega 3

TerraMax Pro has recently came out with their own line of Omega 3 fish oil supplements for dogs. They really focus on quality in their hip and joint supplement and the same can be said of their fish oil. Like several brands on the list, it comes in a easy to use pump bottle.

They offer a “unconditional 100% satisfaction guarantee” with this product but I really don’t think you’ll have to use it since it is a high quality product.  This fish oil is from sardines, herring, anchovies and mackerel with no fillers.  Many reviewers have said it takes just a few weeks to see improvements in their dogs.

3. Grizzly Pollock Oil Supplement for Dogs

Grizzly Pollock Oil

Another product from the Grizzly line, their Pollock Oil comes with the same pump bottle option that the Salmon supplement offers, which is yet another reason to give this company your attention. Grizzly touts their Pollock oil as having the “highest Omega-3/6 ratio,” all coming from a rich, affordable, and sustainable source.

The benefits are apparent, just as they are with the Salmon product: The pump bottle makes delivering servings very convenient and clean, and the fish oil itself is well sourced and of a higher quality than competing products. As a bonus, the Pollock oil is also priced to be an affordable alternative to the Salmon oil at similar volumes. The recommended dosage of one pump per 25-30 pounds is also identical.

4. Vetoquinol 250 Count AllerG-3 Fish Oil Supplement for Dogs

Vetoquinol AllerG-3

One of the best sellers online, the AllerG-3 fish oil supplement from Vetoquinol is also one of the best available in capsule form. Each capsule provides 2000 mg of fish oil in the Large Dog formula, but they also include Vitamins A, D3, and E. As mentioned earlier in this article, a supplement that balances Vitamin E levels with fish oil supplement levels is very crucial in maintaining proper dog health, so consider this capsule product to be one of your smarter options.

Dosage levels vary by size, but at a 250 count, you could easily have six months-to-a-year’s worth of fish oil supplements for your dog. Each supplement also contains the right amount of EPA/DHA, the key ingredients in fish oil that make it such an effective health product. AllergG-3 is sourced from cold water fish caught in the wild, which can give you peace of mind when searching for pure sources of fish oil on the market.

5. Alaska Naturals Salmon Oil Coatcare for Dogs

Alaska Naturals Salmon Oil

Another product delivered in a bottle, Alaskan Natural Salmon Oil Coatcare has many of the benefits that you will find with the Grizzly product, with a few differences. Namely, Alaskan Natural’s fish oil solution is stabilized with Rosemary extract. Rosemary is an antioxidant, which can help to eliminate some of the odor associated with the natural salmon oil found in this product. The level of fat variety is not as varied as the Grizzly formula, nor does it have the vitamin E that you will find in AllerG-3. That said, customers do report that the product is effective in providing the benefits that you’ve come to expect from a fish oil supplement. Just make sure to purchase a Vitamin E supplement additionally.

Also of note, Salmon Oil Coatcare only contains Omega 3 fatty acids. It does not contain Omega-6s, or other varieties. This could be a positive, or a negative, based on your pet’s dietary needs. Take it into consideration.

6. Nordic Naturals Omega-3 Pet

Nordic Naturals Omega-3

Finally, we have Nordic Natural Omega-3 Pet. Unlike others on the list, Nordic Natural’s product is derived from wild caught anchovies and sardines, which are also high in Omega-3 content. You will still find the Omega-3s, EPA, and DHA that you’re looking for in a pet dietary supplement, it just comes from a different source.

Another key difference is the price; Nordic Natural is the most expensive on the list per ounce. What you get is a fish oil supplement sourced from the South Pacific Ocean, near Peru. Touted as the “number one fishery in the world” for quality of fish and sustainability, the product does have some bonafides as to where you’re actually getting your fish oil.

While it may be more expensive per ounce, you will find that the dosage levels are actually lower. As little as a half a teaspoon is recommended for dogs between 20 and 40 pounds, with dosages moving up in half teaspoon increments per 20-30 pound differences. In other words, a little goes a long way.
