We’re always searching for the next “wonder product” that can guarantee our dogs’ health and vitality. Unfortunately no such thing exists, but the natural compounds found in fish oil come pretty darn close!

Fish oil contains two essential Omega-3 fatty acids – EPA and DHA. The canine body is only able to synthesize them in limited quantities so many pup parents turn to supplements to give their dogs a boost.

Here are 10 amazing ways that a simple, tasty fish oil capsule can improve your pup’s health and wellness.

1. Promotes Nervous System Development In Puppies

DHA is an important ingredient in human prenatal vitamins because it promotes nerve growth, brain development and vision in mammals. Just like babies, puppies benefit from this Omega-3 fatty acid while in the womb, nursing and as they grow and develop into adults.


2. Offers Anti-Inflammatory Properties

Both EPA and DHA are important components of cell membranes. They signal cells to decrease inflammation. Less inflammation means less pain, redness, swelling and irritation of the skin, joints and internal organs.

3. Helps Ease Arthritis Pain

With their powerful anti-inflammatory properties, the Omega-3 fatty acids in fish oil can have profound benefits for senior dogs with old, achy joints. Even if your dog does not have arthritis, adding a fish oil supplement as your pet ages can help prevent joint problems and keep your pooch comfortable longer.

4. Reduces Skin Allergies

Skin allergies are another form of irritating inflammation. The redness, itching and painful hotspots that come along with chronic allergies may be significantly reduced by adding fish oil to your pet’s diet.

5. Promotes A Healthy Shiny Coat

If your dog is lucky enough to be free of skin allergies, he or she can still reap the skin benefits of fish oil. Fat supplements reduce shedding and dandruff and promote soft, shiny coats.

6. May Encourage Picky Eaters

Dogs love stinky fish and high quality Omega-3 fish oils are derived from doggy delicacies like salmon, tuna, herring, anchovies and mackerel. If your pooch is a finicky eater, adding fish oil just might do the trick!

7. Strengthens Immunity

Fish oil has been shown to enhance B-cell activity, a type of white blood cell that aids in the immune response. This, combined with its ability to improve blood chemistry and reduce inflammation makes it a powerful immunity booster.

8. Acts As An Antioxidant

While Omega-3 fatty acids do not rank among the “super” antioxidants, a study in the August 2002 Journal of the American College of Nutrition reports that they do lower free radical levels and may also increase the body’s ability to manufacture antioxidant enzymes.

9. Promotes Cardiovascular Health

Although the claim that fish oil reduces the risk of heart attack and stroke is unfounded, there is evidence that it can help lower blood pressure, cholesterol and triglycerides in the blood – all of which promote a healthier heart.

10. May Slow The Growth Of Certain Cancers

Many veterinarians have started recommending fish oil to their patients with cancer or at high risk for cancer. Recent studies have shown that fish oil may slow the growth of tumors, although more research is still needed in this area.

As pet parents ourselves, and also concerned about the lack of Omega-3’s in most canine diets, the team at iHeartDogs recently spent over a year working with a holistic vet to develop our own line of Omega-3 supplements. We can honestly say we believe these products have the most complete formula on the market today. And even better, they all help shelter dogs!
