Fish Oil For Dogs: The Benefits & Proper Dosage

fish oil for dogs

Fish oil is not just good for dogs – it’s great for them! In fact, most canine nutritionists would agree that fish oil with the proper amounts of EPA/DHA is probably the single most beneficial natural supplement you can provide man’s best friend. So why aren’t your giving your dog the same health boost you provide yourself?

Please keep reading as we discuss the role of fish oil in a dog’s diet, and how much to administer to reap its enormous benefits.

What Does Fish Oil Do For Dogs?

The benefits of fish oil for dogs are virtually identical to those we previously described for cats, although its efficacy for treating dogs is even more firmly-established.  As we discuss below, the potent anti-inflammatory agents in fish oil (Omega three long chain fatty acids) can prevent and treat a wide variety of canine maladies.

On the more cosmetic side, fish oil can promote a supply, shiny coat of fur and reduce or treat skin irritation and dandruff.  It can also lessen shedding, a huge bonus for most housedogs and particularly their owners.

It’s beneath the surface however where fish oil really works wonders. Supplementation for dogs is widely accepted to treat many conditions, including allergies, arthritis, GI disorders, auto-immune disorders, heart disease, kidney problems, hypertension, high blood cholesterol, and even cancer.  Moreover, fish oil supplementation has also been reported useful towards maintaining a proper bodyweight, increasing activity, and heightening cognitive function in both older dogs and puppies. Importantly, this “mental enhancement” effect observed from dosing with fish oil is believed to also accrue to fetuses (and carry over to puppies) when this supplement is ingested by their mothers – a finding that’s been corroborated in at least one human study!

How Much Fish Oil ?

As far as dosing, this is very easy and does *not* require mathematical precision. While you should always consult with a licensed vet before proceeding with any supplementation regime, most reputable sources agree that for both cats and dogs, you should aim for providing a minimum of about 20 milligrams of EPA and 12 milligrams of DHA per pound of body weight each day.  In other words, if your dog is 5 pounds, you’d need roughly 100 mg. of EPA and 60 mg of DHA. If fluffy is closer to 50 pounds, then you’d be shooting for 1000 mg/600 mg of EPA and DHA, respectively.

Administering Fish Oil to Your Dog

Some dogs take to fish oil taste/smell more easily than others, but most will accept the pill stuffed into a food or a treat. For dogs averse to pills, just puncture the gel cap and squeeze out the amount of oil needed over food. Or better yet, buy fish oil liquid to add to the food so you aren’t popping caps each day. Doesn’t get much easier than that!

Fish Oil Side Effects?

Don’t freak out if you’ve slightly overdone the dose! The two most likely side effects of going overboard are mild diarrhea and halitosis – i.e., a common case of bad breath. Nevertheless, keep things within the ballpark and watch out for particular conditions that may require closer attention. For example, since fish oil tends to thin the blood and can suppress immune function (albeit at much higher doses), make sure your vet approves any supplementation for dogs that are weak, immune-suppressed naturally or due to steroid treatment, or are at risk for bleeding.

Which Fish Oil is Best?

Although you can certainly purchase fish oil made specifically for dogs and cats, such as Nordic Naturals Omega-3 Pet 180 Soft Gels, the pills made for humans are just as good but may be more tedious to dose for smaller dogs that need very little oil. In any event, just remember to avoid fish oil with vitamin D added, as this is reported to exceed the amount of vitamin D they can handle and subsequently cause unwanted soft tissue and bone mineral deposits.

Fish Oil For Cats: What Does it Do & How Much?

Fish Oil For Cats

Fish oil’s constituent active long-chain fatty acids, Eicosapentanoic Acid (EPA) & Docosahexanoic Acid (DHA), are some of the most well-studied natural health supplements around. Therefore, it’s not surprising that its potent health effects have been found to accrue not only to humans. Among mankind’s other furry companions, cats can also benefit from its anti-inflammatory powers as well. Moreover, it’s powers go much further than merely promoting a shiny coat. Read on for a better idea of the virtues of fish oil for cats and how to go about administering it.

What Does Fish Oil Do For Cats?

Since the most medically established uses of fish oil are related to human cardio-vascular health, you may be thinking:  what can fish oil do for my cat anyway?

As we’ve explained elsewhere, the wondrous properties of fish oil’s two key Omega-3 fatty acids, EPA and DHA, are believed to stem in part from its ability to reduce inflammation. The consequences of this cannot be understated, since there are so many diseases/conditions associated with inflamed tissues – many of the same conditions that affect cats and people alike.  For example, human and feline conditions such as allergies, autoimmune/skin disorders, osteoarthritis – and even cancer – are believed to have their genesis in some type of inflammation.

Of particular note are the results of a 2012 double blind study conducted in the Netherlands and reported in the Journal of Animal Physiology regarding the efficacy of fish oil for the treatment of feline osteoarthritis. Over 10 weeks two study groups of cats were given food supplemented with either fish oil containing Omega 3 (EPA & DHA) or a vegetable oil infused with a fish odor (i.e., the placebo). Neither the cats  – or their owners – knew to which group they belonged.

After the data were analyzed, the researchers concluded that cats that consumed the fish oil were more active, showed greater flexibility, were more outgoing and demonstrated a greater jumping ability compared to the placebo group.

In addition, there are other potential benefits that may not be as profound but are also advantageous for your cat and you.  These include things like promoting cardiovascular health, maintaining/improving kidney and bladder function, strengthening/adding luster to the coat, preventing urinary problems, treating dandruff and reducing hair loss.

Finally, as with fish oil testing on humans has demonstrated, the benefits of Omega 3 on central nervous system function and fetal development may apply to cats as well. This only makes sense, since Omega 3 has been associated with improved verbal scores in human children whose mothers consisted of Omega 3 rich fish.

Recommended Fish Oil Dosage For Cats

Any fish oil supplementation for your cat should be prescribed and/or supervised by a licensed veterinarian.  However, it appears that the consensus of sources indicates delivering at least 20 milligrams of EPA and 12 milligrams of DHA per pound of body weight daily to your cat to reap the majority of the benefits of fish oil.  So, for example, for a 5 pound cat that would be at least 100 mg of EPA and 60 mg of DHA; and for a 10 pound cat, 200/120 mg of EPA and DHA would be recommended, respectively. Please take note that supplements vary significantly in the amount of EPA and DHA they actually deliver, so pay close attention to how much of each your pills/tablets contain so you deliver the recommended dosage of these two components.

Please also be careful when purchasing supplements to avoid those containing vitamin D.  According to an article by Petmd, the vitamin D levels in many fish liver oil supplements can be far in excess of the limits deemed safe for both cats and dogs; as such, the usage of these D-fortified oils may result in deleterious mineral deposits in the kidneys and other soft tissues, in addition to causing bone disorders.

Administering Fish Oil to Cats

Giving fish oil to your cat is easy. You can either embed a gel cap in food or a tasty treat, or if your cat is a bit more finicky, you can pierce the gel and simply pour it over its food. And if you get tired of popping soft gel caps every day, you can always purchase fish oil in pure liquid form.

Fish Oil Side Effects For Cats?

While it’s advisable to work up to the recommended dosage of fish oil gradually, there is little threat to dosing slightly more than needed, so don’t panic. Indeed, the most likely side effects from supplementing with fish oil for cats are generally limited to a cases of mild diarrhea and bad (fishy) breath. However, given its tendency to interfere with blood clotting factors and suppress immune function (albeit at higher doses than those mentioned here), you should make sure to consult with your vet for any cat that is already immuno-compromised, is being treated with steroids,  is being given blood thinners, or is otherwise at risk for excessive bleeding/infection.

Do I Need Fish Oil Specifically For Cats?

While there are fish oils available that are specifically marketed for dogs and cats (these usually come in handy if very low doses are needed), the kind made for humans is just as good and may be more economical in the long run. Just remember to cut the human-sized dose where necessary to avoid wasteful over-supplementation.
