Best Fish Oil For Dogs – Can Dogs Eat Fish? Your Buying Guide

Regardless of the type of diet that you feed your dog, one of the most vital supplements you can add is the best fish oil for dogs. So perhaps the question, we need to ask: why is fish oil good for dogs? Fish oil forms one of the most vital pet supplements that help to keep their minds, bodies, and coats in top shape.

A respected journal on the subject states that fish oil may be the most important supplement you can give your dog.  Fish oil contains Omega 3 fatty acids.  And the Omega 3 for dogs found in fish oil comes with lots benefits, for sure. 

​Fish oil helps improve the skin and coat of all dogs.  It also helps with inflammation that can come with allergies or arthritis.  in addition, fish oil, or fish oil pills for dogs, can promote weight loss and brain function.

But the truth is that not all fish oil is equal in value. The fish oil source, purity, and levels of concentration make a big difference.  so make sure you don't just go for the cheapest.  Get the ones with the highest ratings -- the most popular -- as we recommend below.


Below we list some of the top fish oil for dogs products.  These are the best selling and most popular fish oils for dogs currently available on the market.  The "Servings" assume a 25-lb dog.

Remember that MORE fish oil is not necessarily better.  3-10% of people who have used these products find that their dogs do not tolerate it well.  So start slowly with a small dose, and then try more if you are successful. Use caution if you exceed the dose on the package!  Be sure to keep any liquids or capsules tightly capped and refrigerated, as described on SFGate.com. Similar to olive oil, the things that make oils go bad are light, heat, air and time.

What Are Omega Fatty Acids?

If your dog consistently feeds on foods rich in Omega 6 fats, he or she may require fish oil (Omega 3) to help in balancing out his diet. Omega-6 rich foods are basically plant-based and heavy in grains. If, however, your dog feeds on a largely grain-free diet composed of grass-fed raw meats, it may not be necessary to supplement with fish oils.

Either way, however, it is best to consult your vet prior to changing or adding something new to what you feed your dog.

Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs). There are basically 3 commonly supplemented omega-3 fatty acids types:

  • EPA
  • DHA
  • ALA

Both EPA and DHA are found in marine oil (key sources include fish, squid, krill, and eggs) ALA is typically found in plant oils (key sources include flaxseeds, hemp, walnuts, etc.)

Because your pet dog can’t generate his own omega-3, he will need to get it through the daily diet. Ensuring your furry friend is getting adequate and correct amounts of omega-3 fatty acids is important as it has several positive effects on his overall health.

Does Your Dog Need Extra Omega-3?

It is important to note that Omega-6 fats are not bad for your dog’s health. This is because omega-3 and 6 fats manage important body hormones and are therefore both essential. If your dog consumes excess or too little of either, then his hormones and the immune system are likely to become imbalanced.

You may ask, what then is the correct balance? It is generally suggested that an ideal ratio of omega-6 to omega-3 fatty acids should be 4 to 1. Some dogs could still benefit by getting more omega-3 oils content in their diet.

Besides diet, there are several other factors that might make supplementing the diet of your dog with essential fatty acids necessary. Puppies, for example, have a higher need, as do pregnant and breastfeeding dogs. Another category is dogs recovering from injury or suffering from a chronic disease.

Symptoms of deficiency in omega-3 include:

  • Dog fatigues easily
  • Joint pain
  • Itchy/flaky/dry skin
  • A dry coat
  • Brittle nails.

When you add to fish oil to your pet’s diet, it provides positive anti-inflammatory effects. It also helps in relieving itching due to any skin allergies. If you think your furry pal isn’t getting sufficient amounts of omega-3 from the standard diet then you may consider giving him or her additional fish oil supplementation for better health. It is also possible that his environment demands more omega-3 essential fats.

Fish oil has been shown to be good for pets! Although vets first utilized forms of fish oil in treating canine allergies, they are now recommending it for a broad range of health conditions that range from arthritis, cholesterol to kidney disease.

To Give Fish or Fish Oil

When deciding whether your four-legged companion would benefit better from fish oil or eating fish – or whether they are even required at all, the answer will really be dependent on a number of complex factors.

If your dog generally eats a raw healthy diet chiefly made of grass-fed animals that are free of grains plus vegetable oils, then all he will need is the occasional fish meal.

If, however, he is suffering from injury, stress, chronic disease, or is still growing, then it may be a good idea to supplement with fish oil.

Your dog’s condition will determine whether the supplementation will be required for the long-term or not.

For dogs that feed on a grain-based, processed diet, then you may need to give a combination of high-quality fish oil and fish to make sure he is getting benefiting from whole fish as well as the additional EPA and DHA.

Fish Oil Dosing

You can use fish oil products manufactured for either humans or pets. The EPA and DHA amount in different fish oil preparations varies. Buy concentrated forms when you need to give high doses so that you will end up using smaller amounts of fish oil.

Writing for The Whole Dog Journal, Mary Straus recommends giving your healthy dog between 100 and 150 mg DHA and EPA per each 10 lbs. of body weight each day. If your dog has any health problems, you may increase the dosage up to 300 mg for every 10 lbs. of body weight daily. An ounce of canned boned fish (pink salmon, sardines, and jack mackerel) one averages comes to around 300 mg DHA and EPA combined.

High fish oil doses could interfere with platelets, leading to increased bleeding in case your dog gets injured. Platelets aid in blood clotting. Too much of fish oil, rather than cut down on inflammation, can actually contribute to it.

Although similar to most fish oils, cod liver oil also contains high vitamins A and D levels. Therefore, don’t give your pet high cod liver oil doses. If your dog is need of extra omega-3 fatty acids, simply add some plain fish oil.

Side Effects of Pet Fish Oil Supplements

Overall, supplementing your pet’s diet with fish oil has positive results on his or her health. Nevertheless, similar to any good thing, there is the other side of the coin as too much of anything good may also have adverse health effects.

  • The EPA and DHA anti-inflammatory effect increase the generation of some chemicals that tend to alter the platelet function. Produced in the bone marrow, platelets are cells that aid in blood clot formation. This becomes very significant if your pet needs surgery, especially where there is a possibility of heavy blood flow.
  • The anti-inflammatory EPA and DHA properties also interfere with the process of wound healing. This can have serious consequences for your pet if he has to undergo an extensive or complex surgical procedure.
  • The inflammatory response of white blood cells and the immune system is important in effectively controlling cancer, infection threats, and other medical abnormalities. The EPA and DHA anti-inflammatory effects may interfere with this vital function.

Before dosing your furry friend with fish oil designed for human consumption, it is wise to consult your vet, particularly when it comes to dosage. Pets that suffer from allergies might require higher dosages than the standard.

Conclusion:

It’s important that you pick a fish oil product that makes the work of serving your dog convenient. Fish oil that come in the form of gel-caps are very convenient as the majority of dogs will easily eat them when you mix with food. Most dog owners prefer breaking open the gel and pouring the fish oil liquid directly on the pet food.

Liquid fish oils could be quite messy, so when selecting, choose one that comes with a pouring cap or good pump. If your dog doesn’t like pills, these products come with the advantage of being simpler when it serving.

If you are asking yourself, what are the benefits of fish oil for my dog, I can confidently tell you that they are many. However, the primary benefit of fish oil supplementation is to balance out the omega-6 fats that are more inflammatory.

If the bigger portion of your dog’s diet contains omega-6 fats, then he might need regular fish oil for dog’s dosage to strike a healthy balance. Puppies, pregnant and lactating dogs need higher doses of essential fatty acids. Small quantities of fish oil make a good supplement in those cases.

Understanding the different factors that contributing to a quality and safe fish oil supplement for your pet is important. There's certainly a lot of information out there regarding diverse pet supplements, and we hope this comprehensive post has helped in clearing some of the critical issues.

Is fish oil good for dogs? We can conclude by telling you that for sure that fish and fish oils are strongly recommended for your pet.

    I tried the Zesty Paws and waited a while before I posted a review. i got it Oct 15th. By Nov 120th my dog stopped shedding. He’s a male American Staffordshire Bully. 13 months old. Bullies with white fur frequently have sensitive or dry skin. So i was hoping the fish oil for dogs could help him from the inside out. The vet said salmon oil, or butter or chicken fat. Man oh man, what a difference. Just great stuff!
