Best Dog Omega-3 Supplements | Review & Buying Guide

Dog supplements come in different forms and types to help your dog stay healthy. One of those supplements is the omega-3 fatty acids which are increasingly becoming popular for different breeds of dogs. These nutritional products are advertised year-in-year-out to help your canine friend with healthy skin conditions, kidney functions, allergies, heart diseases, cognitive function and so on.

Even though more research is needed to establish if there are other uses of omega-3 fatty acids, it’s evident that their use has yielded positive results. As such scores of veterinarians have recommended and encouraged dog owners to use this nutritional supplement to prevent or treat diseases that might affect the growth and development of their pets. That is when the need to know what omega-3 supplements come in and how you can use them safely to give your dog the best results.

On the scientific point of view, omega-3 fatty acids are actually molecules made up of chains of carbon atoms and oxygen double-bonded with a hydroxyl group (hydrogen and oxygen atom) that is single-bonded at one end. In other words, omega-3 fatty acids are commonly referred to as “polyunsaturated”. This means that these supplements have multiple double-bonds distributed throughout the carbon chain with their double-bond located between the carbon atoms as number 3 and 4 when you count them starting from the end of its chain far away from the hydroxyl groups.

Inasmuch as this information might sound somehow technical and confusing, it is important to have it at the back of your mind for a number of reasons. To begin with, omega-3 fatty acids have double bonds that are somewhat not stable making them the best candidate for oxidation. This phenomenon, however, results in rancidity.

Additionally, dogs have no ability to make their own omega-3 fatty acids. This is because the dogs are physiologically not able to put up the double bond in-between carbons three and four. That is the main reason dogs need omega-3 fatty acids such as docosahexaenoic acid (DHA) and eicosapentaenoic (EPA) to promote and improve their health.

The source for omega-3 fatty acids is not just limited to fish oil alone but you can also get it from certain vegetable oils like canola oil, flaxseed oil, soybean oil, and walnut oil. These are rich sources of omega-3 known as alpha-linolenic acid (ALA) that is regarded as a precursor to DHA and EPA.

One thing that you need to know is that dogs are not so good when it comes to transforming ALA into DHA or EPA. In this case, it is a good idea to provide your dog with enough DHA and EPA directly. And the best way of doing so is through sources such as salmon oil (or any other cold water fish oils) and other types of algal oil.

There are commercially available types of omega-3 fatty acids supplements but they have completely different DHA and EPA concentrations. Apart from that, the exact dosage of omega-3 supplement that needs to optimally treat a number of different health conditions in your dog is not yet known with any amount of certainty. This makes it difficult to know the exact amount of omega-3 fatty acids you can give to your dog to get the best results.

Some studies suggest that you can give your canine friend around 22 to 40 mg/kg per day of the EPA if you are expecting to see some beneficial effects. But you need to keep in mind that quite a number of fish oil supplements have both the EPA and DHA thus making the total dose of this supplement to be higher.

However, omega-3 supplement is very safe but when you administer to your dog in larger doses, it can lead to some complications such as gastrointestinal upset, immune dysfunction, and issues with blood clotting system.

When buying omega-3 fatty acid supplements, look out for one that is manufactured by a reputable company and should provide you with the following information right on their websites or product label:

  • The amount of DHA and EPA contained in the supplement
  • How the supplement is purified to get rid of harmful contaminants like mercury
  • The preservation method used in preventing rancidity

Most importantly, ensure that you pay your local vet a visit to learn more about multiple health benefits that the supplements can bring to your dog. Otherwise, this article will take you step by step to the great benefits of giving your dog omega-3 supplements, the side effects and a review of a few products related to this supplement. Keep reading to find out more.

Benefits of the Best Dog Omega-3 Supplements

Omega-3 fatty acids are derived from the tissues of certain types of oily fish. More often than not, these oil fish are what experts refer to as essential oils because the body cannot produce them on their own but need them to assist in some physiological functions.

According to studies, there are functional and facilitative fats as the two most important types of fats that are essential for dogs today. Functional fats are very important in the functioning of the body as the name suggests. Pets cannot produce these types of fats on their own thus prompting dog owners to seek for an alternative from other sources. One of the major sources is omega-3 fatty acids which play a very significant role in the development of brains and body in general.

The second category of fats are the facilitative fats which are also referred to as saturated fats. They enhance your pet’s food, convert to energy, assist in the absorption of vitamins and aid in digestion.

Omega-3 fatty acids supplements for dogs come in three major categories and these are:

  • Alpha-linolenic acid, also known as ALA
  • Docosahexaenoic acid or (DHA)
  • Eicosapentaenoic (EPA)

Each type of omega-3 fatty acid plays its own role. But most importantly let’s look at the benefits of omega-3 dog supplements in general. As a dog owner, why would you go for omega-3 fatty acids to supplement your dog’s diet? Here are the main reasons why you probably should consider giving your pet this essential nutrient:

  1. Omega-3 fatty acids supplements can fight cardiovascular disorders
    Studies have shown that omega-3 supplements can help fight cardiovascular disorders. Also, these supplements can help with the inflammation around your dog’s heart and other vital organs within the body. At the same time, omega-3 fatty acids can be beneficial in reducing muscle loss as well as damage.

  2. Cognitive function and neurological health
    Researchers have proven that when young dogs are subjected to a diet containing omega-3 supplements, they are likely to have a stronger ability to learn and acquire new tricks in the process. In addition, the same puppies can follow commands better than those that are not fed on diets containing omega-3 fatty acids. Therefore, it can be said that omega-3 supplements for dogs are important in promoting cognitive function as well as neurological health in dogs.
  3. Omega-3 supplements help in inflammatory skin disorders
    The omega-3 fatty acids are known to be a good choice of dietary supplements for your dog because it has anti-inflammatory properties and can also help control itching and loss of hair associated with skin allergies. In the real sense, EPA (one of the two types of omega-3 fatty acids) is an anti-inflammatory and can help your dog with any health condition that is likely to cause inflammation of the kidneys, heart, joints, and kidneys among others. Generally speaking, this supplement plays a crucial role in controlling skin disorders in dogs. This can be the best way to decrease all incidences leading to hot spots on the dog’s skin.

  7. Omega-3 fatty acids promote greater mobility in dogs
    The EPA, a component of omega-3 supplement possesses excellent anti-inflammatory effects which are assisted by the inflammatory activities of DHA to give your dog its overall mobility. This is helpful especially when it comes to preventing inflammation in the dog’s joints, allowing it to walk or run around freely without any constraints. Mostly the elderly dogs are the ones affected the most but giving them omega-3 as their dietary supplement can really help them a lot in overcoming joint problems. The supplement helps minimize the severity caused by inflammatory conditions in order to allow your canine friend to move around a lot better.
  8. Omega-3 supplements promote optimum skin health
    The fact that omega-3 has excellent anti-inflammatory properties, you can rest assured that this supplement will help your dog to achieve healthy skin and coat. Why is the case? The answer lies in the supplement’s ability to promote healthier skin as well as a shiny coat in dogs when given as their dietary supplement to provide them with the essential nutrients.

These supplements are important components with the dog’s membrane of the skin cells. Absence of these wonderful fatty acids means that your dog’s skin will get easily damaged or irritated leading to severe cases of itching, redness and even blotching.

Most importantly the dog’s hair shaft is made up of keratinized tissues which are dependent on those fatty acids to provide them with a smoother feel and shinier appearance. But you can provide your pets with omega-3 supplements to replenish the fatty acids found in their cell membranes making your canine friend’s skin more healthy and resistant against all factors that can trigger skin problems.

Other Benefits of Omega-3 Supplements for Dogs

Promotes immune system functioning in dogs

There’s substantial evidence that supports the idea that the role of DHA is to enhance the overall activities of B-lymphocytes. These lymphocytes are responsible for producing the antibodies and release of cytokines which play a big role in the management of inflammation, infection and even cancer.

Perfect examples of cytokines are tumor necrosis factors (TBF), interferons, and interleukins. All these examples have many effects on your pets by greatly improving the overall functioning of their immune system. This way, your four-legged friend can fight infections more effectively as a result of a combination of cytokines and antibodies regulated by B-lymphocytes. In this regard, you should know that omega-3 fatty acids only enhance the overall functioning of the B-lymphocytes rather than producing them.

Boosts cardiovascular health

Many studies have indicated that supplementing your dog’s diet with the omega-3 does not necessarily reduce incidences of strokes and heart attacks. But it provides protective mechanisms through anti-inflammatory and the antioxidant actions of DHA and DHA.

Much of the emphasis is redirected to the actions and effects of the omega-3 supplements regarding the low-density lipoproteins that are responsible for the risks of emerging atherosclerotic conditions. However, dogs are not susceptible to the cardiovascular conditions in the same way as human beings. This does not imply that they cannot be affected by this condition and if they do, the omega-3 fatty acid is there to boost their cardiovascular health.

Possible Side Effects of the Omega-3 Supplements

It is not always true to assume that every dietary supplement is entirely beneficial to the dogs. Naturally there are two sides of a coin and in the same way, omega-3 fatty acid can be beneficial, it can also bring some side effects to your dog. Therefore, you should be fully aware of the following underlying side effects of the omega-3 fatty acids supplements to your dog:

Can cause premature aging and diseases

One thing you need to know is that omega-3 fatty acids supplements are highly susceptible to the oxidative damage. As such, this comes as very disturbing news given that every time the omega-3 supplements are exposed to the air, oxygen reacts with the fat particles by breaking them down into tiny compounds known as malondialdehyde (the MDA). Then these compounds create molecules that contain oxygen and they come to be referred to as free radicals. When combined with the MDA, free radicals can cause premature aging and significant damage to all essential proteins as well as other important cellular structures. As a result, these damages ultimately lead to irreversible diseases to your dogs.

They can cause toxins

The truth of the matter is that omega-3 is part of fats extracted from fish. These types of fats are usually loaded with toxic materials. If you are wondering how they become toxic, then you should trace back their sources and this will take you back to the oceans where most of the fish come from.

Of late oceans have become the damping sites for all types of dirt, harmful materials, and toxic substances. All these foreign materials pollute this natural fish habitat with cadmium, arsenic, mercuryand even lead which are chemicals responsible for contaminating oceans at an alarming rate.

As usual, these chemicals are not broken down so fast and they end up finding their way in the environment inhabited by fish and eventually get consumed by the same fish. When omega-3 is extracted from such fish, chances are it will have toxic substances like heavy metals. If they are given to the dogs as supplements, they may lead to dysfunction of the animal’s nervous system, cause certain cancers, blindness, kidney and liver damage and consequently, death. This may sound scary but it is important to equip yourself with this knowledge.

Poisoning from radiation

There have been numerous cases of nuclear power plant accidents such as the 2011 Fukushima accident that was caused by a tsunami. This causes nuclear materials, which are radioactive in nature, to seep into the nearby ocean waters. And there’s no way of preventing marine creatures including fish from getting contaminated with the radioactive water that continuously keeps on seeping into the ocean from coast to coast, far and wide.

Likely these dangerous radioactive materials get into contact with fish and when essential oils are derived from them, it is obvious that they are already contaminated and in the long run, they may poison your pets when given to them as supplements. But you can avoid all that by simply asking for the Certificate of Analysis (COA) from your supplier should you choose to provide your dogs with fish oil or omega-3 fatty acids supplements.

Slow blood clotting

Experts have found out that omega-3 fatty acids supplements are responsible for the slow blood clotting. This supplement, though very important as a dietary supplement for dogs, can decrease the ability of platelets in the blood to stick together or clot. While this effect is more dangerous for cats as compared to dogs, it is prudent that you take precautionary measures before subjecting your dog to omega-3 supplements. Consult with your local vet for guidance before giving your canine friend this type of supplements.
