10 Best Fish Oils For Dogs 2021: Reviews & Buyer’s Guide

Fish oil is one of the easiest add-ons to your dog’s food diet. Fish oil improves the heart health of your canine companion, encourages a silky coat, prevents itchy, flaky skin, and soothes allergies and joint pain. This can also make their immune system stronger and help them fight cancer.

That is because fish oil contains omega-3 fatty acids, an essential healthy fat that helps the body and brain of your dog. Unlike humans, dogs are unable to produce omega-3 fatty acids on their own and have to get them from their diet. Whether you make fish oil a part of the dietary routine for your dog, here’s what you need to know.

As a health-conscious pet parent you want to give your best. Most of us are well aware of the many benefits that fish oil has for humans, but did you know that these benefits apply to your furry friends, too?

Fish oil is one of the most common supplements to a healthy diet for both humans and canines. An excellent source of omega-3 fatty acids, it is obtained from marine animals such as tuna, salmon, mullet, and anchovies. Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) present within these fatty acids are directly responsible for many of these benefits.

4 Benefits of Fish Oil for Dogs

1. Arthritis Relief

Omega-3 fatty acids are an anti-inflammatory savior for dogs with arthritis, with their therapeutic benefits. The Multicenter Veterinary Practice examined 127 dogs over 60 days while they were being given their daily omega-3 dosage. The dogs showed significant improvements in their ability to comfortably play, walk, and rest. That’s one reason why dogs are given nutrients such as fish oil.

2. Naturally Treats Skin Conditions

The above mentioned anti-inflammatory effects of omega-3 also help to heal allergic skin reactions and skin diseases in dogs. Crossover Research using fish oil as a treatment for dogs with different skin disorders showed significant changes including less itching, less animal self-inflicted damage and an increase in the softness and texture of their fuzzy coats.

If your dog suffers from a serious inflammatory disorder, they can not be completely cured by fatty acids alone; however, omega-3 may be able to enhance the effectiveness of drugs used to treat their disease.

3. Cognitive Functions

Canine Cognitive Dysfunction is a common condition in older dogs which resembles Alzheimer’s disease in humans. Daily doses of DHA, the omega-3 fatty acids found in fish oil, are believed to enhance the cognitive functions of infected dogs and their human counterparts.

4. Naturally Treats Kidney Disease

Fish oil is often prescribed to kidney diseased dogs to combat symptoms such as severe protein loss. Fish oil can have a protective effect against acute kidney injury according to Pet Health Network and the Department of Internal Medicines.

The omega-3 fatty acids also help to reduce glomerular disease, thereby improving kidney function in dogs affected. Some studies suggest that fish oil can have a protective effect against acute kidney injury and can be a perfect solution to help relieve impaired function in the kidneys.

Most commercial dog foods contain low levels of omega-3 fatty acid but may have omega-6 fatty acid instead, which causes inflammation. As a consequence, your dog’s diet could actually make it susceptible to inflammatory diseases.

How is Fish Oil good for Dogs?

Initially used for the treatment of canine allergies, fish oil is now used to treat other conditions as well, including arthritis and high cholesterol. Two essential fatty acids are present in the fish oil supplements: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Such compounds are not well synthesised by dogs.

In fish such as salmon, sardines and mackerel, these can be found. Each of the two fatty acids has its own particular set of benefits; for example, EPA is an anti-inflammatory agent and helps treat inflammatory conditions and DHA is essential to the development of the brain and eyes in puppies.

The two fatty acids in fish oil have the ability to reduce cellular inflammation. All EPA and DHA are converted to prostaglandins, which can reduce tissue inflammation.

How Much Fish Oil should I give my dog?

Sometimes too much of a good thing can have undesirable side effects. Diarrhea, blood clotting, weight gain, and a weakened immune system may be caused by excessive quantities of fish oil. A dosage of fish oil between 20-55 mg, with combined EPA and DHA per pound of body weight, is healthy for dogs and cats, according to PETMD.

Types of Fish Oils

The omega-3 fish oils are available in two forms, according to Doctor’s Advantage research: the natural triglyceride form or the synthetic ethyl ester form. Fish oil is easier to absorb in natural triglyceride form; however, the ethyl ester form is more common in the market.

1. Natural Triglyceride Oil

The most popular and simplest to digest, is natural triglyceride oil. Nevertheless, it may contain toxins such as PCBs, because it is not filtered. Natural triglycerides are one of the most popular commercial fish oils. Due to their natural form, they resemble the effects of eating fish,as a result of which this type of fish oil is often favored.

2. Ethyl Ester Oil

Concentrate and distill the ethyl ester oil (EE) to eliminate impurities. According to the AKC, you may think of it as “semi-natural with high levels of omega-3, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which are important components.”

The formulated EE allows molecular distillation at lower temperatures, producing higher levels of EPA and DHA than those found in fish naturally. This type of fish oil is called the “concentrate of fish oil.”

Care And Storage Of Fish Oils

It’s important to protect the fish oil from heat, light, and air. Purchase your fish oil and put it in the refrigerator in dark coloured bottles. Since it is susceptible to oxidation, it can get rancid, so be sure to throw it away if it has a strange odor.

Ask your vet how much fish oil is appropriate for your dog instead of following the dose instructions on the box. Make sure the amount of fish oil you give them is appropriate for their size, weight, and age.

It’s hard to feed your dog a completely whole natural diet. With so many artificial additives in some of the dog food today, fish oil may just be the required complement to their dietary needs.

Last but not least, be sure to ask your vet for advice before you start your dog on supplements, and only buy quality items if that is the path you want to take .

Potential Side-effects of Fish Oil for Dogs

Although fish oil is generally ok for dogs, side effects and concerns are recorded before these healthy omegas are included in a dog’s diet. Dogs with allergies to seafood or shellfish should not ingest fish oil, unless suggested as part of a treatment plan by a veterinarian.

Some fish oils can cause bad breath. It won’t really annoy your dog, but you might not like your pup’s fish-breathing kisses. Generally speaking, you can put a stop to this issue by simply reducing the amount of supplement that you provide at each meal.

Some omega-3 fatty acids (including both EPA and DHA) can cause the body of your dog to stop correctly coagulating. This can be particularly problematic for dogs who have a laceration, are scheduled for surgery, or are taking any other medications that also reduce the ability of the blood to coagulate.

The inflammatory-reducing effects of omega-3 fatty acids delay the healing process and reduce white blood cell development, which is used by the body to fend off infections. So you might want to think twice about supplying fish oils to dogs suffering from injury or illness.

Some dogs are unable to adequately digest supplements of fish oil, which can cause bowel distress. While these issues often resolve on their own with time, it certainly isn’t fun in the meanwhile for your dog.

Since your dog food generally already contains good quality omega-3 fatty acids, most pet parents add fish oil to a daily diet only when a veterinarian advises it, for specific health issues. Some side effects, however, can occur such as:

  • Mild oily coat
  • Fishy breath
  • Fish-smelling skin and coat
  • Diarrhea
  • Blood clotting defects
  • Slow wound healing
  • Interacts with some medications

Which Dogs Benefit the Most from Fish Oil?

Although dogs of all ages, sizes, and breeds can benefit from daily supplementation with fish oils, there are only a few classes that can benefit greatly.

1. Older Dogs

Older dogs, particularly arthritis sufferers, will be able to move much more painlessly and comfortably as fish oils help stop and minimize any swelling and inflammation around their joints.

This should reduce their blood pressure, improve their heart, and also lower cholesterol levels.

2. Puppies

Puppies can also hugely benefit from fish oils. Different studies have shown that puppies with an optimal DHA level are easier to train than those without it, due to the cognitive functional effect of the fatty acid.

It also helps boost their immune system to help them battle any disease or infection they may be vulnerable to while young.

4. Dogs With Specific Health Conditions

Obviously, dogs suffering from omega-3 deficiency will also benefit greatly from supplementation of fish oil. Symptoms of this include dry skin and hair, pain in the joints, and rapid fatigue.

And ultimately, it is widely believed that it will help larger dogs that are susceptible to joint problems, with Labrador Retrievers, Golden Retrievers and German Shepherds.
