It is no mystery that fish oil offers benefits to all of us; countless researchers have been done on that topic, but not many people actually know that the fish oil can be extremely beneficial to our dogs as well. Fish oil is considered to be a great diet for dogs, mostly due to the fact that it has exactly the right fats that the dogs need. This, in turn, can help the dogs be fitter and healthier.

Many have been wondering why is it exactly the fish oil that helps the dogs (and cats as well) so much. Well, the answer to this is really simple, and it has to do with the fact that the dogs and cats would intake a lot of fish oil if they were feeding themselves in the wild. This is exactly why adding some fish oil supplements to your dog’s diet could help out a lot and you should do it as soon as possible if you haven’t already. Not having fish oil in their diet could lead the dogs to miss out on some amazing nutrients, which are in fact necessary for the dogs to lead a normal life.

This guide is going to show you everything there is to know about fish oil and how beneficial it can be to dogs, and we are also going to offer you our recommendations on 5 top fish oil supplement product that you can find on the market.

The packaging comes in containers of various ounces, and what’s important to note here is that Grizzly Salmon Oil supplement only uses 100% pure oil retrieved from the Alaskan salmon. This is an amazing supplement that contains more than fifteen various fatty acids, as well as Omega 6, Omega 3, as well as the Arachondic fatty acid groups.

As we have already mentioned, an amazing thing about this product is its pump bottle dispenser, which allows for the bottles to be easily refrigerated and stored. It also allows the dog owners to easily add exactly the right amount of fish oil their dog needs. Also, the pump is highly practical, because it creates no mess. One pump roughly equals about 1,000 mg of fish oil, which is the right amount for a 30lbs dog, which basically allows you to measure the amount of fish oil you wish to serve to your dog extremely easy.

The main reason why this product has found its place on this list definitely has to be the fact that it is naturally sourced. You can always question whether the product actually comes from nature with other fish oil supplements, but here you know that’s true. This means that the product definitely has no mercury in it, and there are numerous tests done to confirm that. The product comes from a 100% natural Alaskan salmon.

Why We Like It – This is a 100% natural product with oil coming from Alaskan salmon. It also has more than 15 various fatty acids, Omega-3, Omega-6, as well the Arachondic ones, which make for an amazing product.

3. Grizzly Pollock Oil Supplement for Dogs

Grizzly seems to be an amazing company because this is already the second fish oil product of theirs that has found its place on our list. The Pollock Oil also comes in a pump bottle, which is just one I the long list of reasons of why this product is just so popular, and why this company has so much attention pointed at it. The company says that this product has the highest Omega-3 to Omega-6 ratio and that the entire product comes from a rich, sustainable and affordable source.

The benefits that this product offers are amazing, just like the benefits of the salmon fish oil product of the same company are. The pump bottle is great and allows for the users to get the oil without creating a mess. And one of the reasons why this particular product is so popular is its low price compared to the similar products of a similar size.

Why We Like It – This product also comes with a pump bottle, which is a huge plus. This particular fish oil supplement has the highest Omega-3 to Omega-6 ratio, which is a great feature of this supplement that comes from a sustainable, affordable and rich source.

4. TerraMax Pro Omega 3 Fish Oil

Recently, TerraMax has also come out with their own brand or fish oil supplies, and it would seem that it is just good enough to find its place on our list. This is a product out of their line of Omega 3 fish oil supplements, primarily for dogs. The quality of this company is something that comes without even saying, as does the quality of this fish oil product of theirs. It is extremely popular, and just like some other products on this list, it comes in a pump bottle, which is extremely easy to use.

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

This fish oil supplement for dogs is one of the best sellers online and is also at the same time the first one on our list that comes in a capsule form. Each capsule is a 2,000 mg capsule full of fish oil, as well as Vitamins A, E, and D3. The 2,000 mg dosage might be too much for some dogs, and that is why it is recommended for dogs under 30 lbs of weight to only take half a capsule. This is an amazing supplement because it successfully balances the fish oil and Vitamin E, which is something we’ve mentioned earlier in this article. Always go for the fish oil products that offer Vitamin E as an ingredient, because it saves you the trouble of giving your dog Vitamin E separately.

This product comes with 250 capsules for you to use, and if you have a dog under 30 lbs of weight, this could easily be turned into 500 capsules! It is also a product that has exactly the right amount of EPA/DHA, which are basically the most important ingredients of a fish oil supplement that allow for all those beneficial things to happen to your dog. The capsules are gotten from cold water fishes from the wild, meaning that the product comes from 100% natural sources.

Why We Like It – This is one of the most popular fish oil products, and the first one on this list that comes in the capsule form. Each capsule offers 2,000 mg of fish oil, but apart from that, other ingredients include Vitamins A, D3, and of course, E.

6. Alaskan Fish Oil for Dogs

This fish oil supplement is another one that comes to us in a bottle, and is quite special in the sense that it comes with a Rosemary extract which is being used here to stabilize the solution. Rosemary is really important in that sense because it is an antioxidant, which is great in eliminating that terrible odor that some fish oils seem to have. Some of the downsides of this products are the fact that does not have Vitamin E as an ingredient, nor does it have a varied level of fat variety as some other products, most notably the Grizzly ones. However, the product seems to be highly effective nevertheless, and that is proven by the fact that it is extremely popular with the dog owners, and that they themselves admit that the product is great.

It should also be mentioned that this product does contain Omega-3 fatty acids, but unfortunately, no Omega-6 or any other varieties of these acids. Some dogs may find that positive, while others might find that to be a negative thing, it all depends on the dietary needs of the dog.

Why We Like It – This fish oil supplement is a bit different in a sense that it uses Rosemary for stabilization, which helps the product to get rid of the terrible smell. The variety of fatty acids isn’t that high, and it does not have Vitamin E as an ingredient.

7. Nordic Naturals Omega-3 Pet

And the second to last fish oil supplement on our list is the Nordic Naturals Omega-3 Pet, which is a bit different to all the other products on this list in a sense that it derives from the wild anchovies and sardines. This means that there is still a lot of Omega-3, as well as EPA and DHA content in this product, with the only difference being the fact that it comes from a bit different source.

Also, the price is very different than the prices of all the other product mentioned here, because this one seems to be the most expensive one out there. This is due to the fact that the fishery where the fish oil comes from is located near Peru, and is considered to be the best fishery in the entire world! It is sustainable and has quality fish, meaning that you won’t have to worry about the quality of the product – it is all 100% natural and from a respected source.

Even though the prices are higher, the dosages here are actually lower. It is recommended that the dogs that weigh between 20 and 40 lbs should only get a teaspoon of this fish oil, and the dosage moves up a half a teaspoon for every additional 20-30 lbs of your dog’s weight. This means that the product may cost more, but it is definitely going to last longer, and that counts for something.

Why We Like It – Nordic Naturals Omega-3 Pet is a supplement obtained from wild anchovies and sardines, which are full of Omega-3 fatty acids, EPA and DHA. It is the most expensive product in this list but is also the one that is going to last the longest.

We’ve given you all the basic information and benefits that the fish oil supplements could offer your dog, but we believe that it is also important to tell you which fish oil supplements are the best ones on the market in order for you to know what to buy. Keep in mind that all of the products here are completely natural and from natural sources, and have been inspected and have had their safety, quality, and the correct measuring of dosage screened. So, here are some of the fish oil supplements that we believe to be the best ones on the market.

Top 4 Benefits of Fish Oil for Dogs

Healthier skin and fur. Fish oils are rich in Omega-3s which can help your dog have a much nicer and shinier hair and coat, and it can also do wonders to their skin.

Fish oilReduced shedding, as well as dry skin and inflammation.

This happens because the fish oil can moister the skin, which eventually leads to a better appearance, as well as to a reduced inflammation (even on the cellular level), which leads to less shedding. Find dog foods that can reduce shedding here.

Improved stamina and immune system. This happens due to reduced inflammation. This also means that your dog will have a lot more energy for combating other diseases and illnesses, and the viruses and bacteria won’t cause him problems anymore. Also, this means that your dog is going to have more energy to play with you, to run, jump, and be an overall active dog.

Improved joint health. This is another benefit that comes out of reduced inflammation. The dogs will no longer feel discomfort in joints, which is something that a lot of older dogs do experience, just like humans. Your dog will now be able to be active, have an improved immune system and enjoy better cardiovascular health.

Side Effects Possible with Fish Oil Supplements

Gastrointestinal distress. Of course, some side effects are possible, and one of the most common ones includes gastrointestinal distress. This is something that usually happens when the pet ingests far too much fish oil at one time. These problems are usually noted by changes in the bowel movement of the pet or the levels of flatulence. The best course of action would be taking the pet to a veterinarian, who is going to recommend to you the right dosage of fish oil for your pet. Then, you ought to work your way up to that dosage.

Reduction in clotting. Due to the fact that fish oil is extremely slippery, there were cases of people reporting that their dog’s platelets have issues sticking together, which in turn could lead to the slowing down of the clotting. The best course of action, and especially if you have a dog that is no stranger to getting hurt while playing outdoors, who is frequently getting cut, or who is roughhousing with other dogs, is visiting a vet, and asking about the right recommended dosage of fish oil for your dog. Also, dog owners ought to know that under no circumstances should they give fish oil to their dog if the dog is on any blood thinning drugs!

Possible interaction with other anti-inflammatory medication. We’ve already mentioned the blood thinning medications, but the dog should not take any fish oil if he is already on any kind of anti-inflammatory drugs as well. This could lead to dangerous side effects.

How to Calculate the Fish Oil Dosage

  • Under 30 lbs: Consult a vet. The amount will likely be under 1,000 mg of fish oil.
  • 30-60 lbs: 1,000 mg is recommended.
  • 60-90 lbs: 2,000 mg is recommended.
  • 90-110 lbs: 3,000 mg is recommended.
  • 110-140 lbs: 4,000 mg is recommended.

It is not that difficult to spot a pattern here – an extra 1,000 mg of fish oil is recommended for every 30lbs of the dogs’ weight. Keep in mind that this is so mostly because of the fact that the fish oil contains EPA/DHA.

Salmon fish oilsIt almost goes without saying that the dog owner ought to consult a veterinarian because as we have seen above, it is possible for the dog to be suffering from certain issues which are going to lower the recommended dosage of fish oil for safety reasons.

You should consult a vet even if you believe that your dog is not suffering from any conditions or diseases.

Special Note About Vitamin E and Fish Oil

It was discovered that the increased intake of fish oil may result in a decrease of Vitamin E, which is a vitamin that dogs really need. So, before you go ahead and buy a fish oil supplement, make sure you find the one that includes some Vitamin E, or if you can’t find one, you can buy Vitamin E separately and they give it to your dog together with the fish oil.

Vitamin E is important in:

  • Maintaining ocular health.
  • Encouraging a healthy immune system.
  • Reducing the wastage of the muscles and their degeneration.
  • Increasing fertility in dogs.

Therefore, it is important to note that the more fish oil you start giving your dog, the more Vitamin E the dog is going to need. Even though there is a precise formula in deciding exactly how much Vitamin E you ought to give your dog in case you increase the fish oil dosage, it is just important for you to note the correlation between the two. And the best solution for deciding how much Vitamin E you ought to get for your dog is just to go ahead and buy the fish oil supplements with a Vitamin E ingredient.
