When I first got my dog, I was inundated with advice about omega-3 fish oil supplements. Everyone seemed to agree: “More omega-3 is better,” and “Omega-3s are so good, they can’t hurt.” Thinking I was giving my pup the very best, I loaded him up with omega-3s, only to discover later that this well-meaning hyperfocus on omega-3s misses the bigger picture of balance. The truth is, omega-3 fatty acids are vital, but only when they’re balanced properly with omega-6 fatty acids. It’s this balance—not simply “more”—that supports your dog’s overall health.

The Roles of Omega-3 and Omega-6 Fatty Acids in Dogs

Omega-3 and omega-6 fatty acids are categories of polyunsaturated fats that dogs need from their diet because their bodies cannot produce them. These essential fats are crucial for various bodily functions:

Omega-3 fatty acids, mainly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), primarily come from marine sources like fish oil and algae. Omega-3s help reduce inflammation, promote brain development in puppies, improve cognitive function in older dogs, support healthy joints, and foster a glossy coat and healthy skin.

Omega-6 fatty acids, including linoleic acid, are abundant in animal fats and certain vegetable oils. Omega-6s are important in supporting skin barrier function, reproductive health, immune defense, and cellular growth.

The critical takeaway is that both omega-3 and omega-6 play complementary roles; they work together to balance inflammation and immune responses in the body.

Why the Omega-6 to Omega-3 Ratio Matters More Than Quantity

While omega-3s are often celebrated for their health benefits, the body’s inflammatory balance requires managing the ratio between omega-6 and omega-3 fatty acids effectively. Historically, the natural diet of dogs and their wild ancestors included an approximate omega-6 to omega-3 ratio close to 1:1 or slightly higher in omega-6.

However, modern commercial dog diets and processed foods tend to have very skewed ratios—sometimes 20:1 or more in favor of omega-6—which can drive undesirable, chronic inflammation. This chronic inflammation is linked to many common dog health problems including allergies, arthritis, cardiovascular issues, and skin conditions.

Studies indicate that a dietary omega-6 to omega-3 ratio between 3:1 and 5:1 supports optimal inflammatory control, joint health, cognitive function, and skin condition in dogs (Jaffey, Su, Monasky, Hanratty, Flannery, & Horman, 2022).

Debunking the Myth: More Omega-3 Is Not Always Better

Despite omega-3’s well-known benefits, more is not always better. Excessive omega-3 intake can have drawbacks including:

• Digestive upset: High doses can sometimes cause diarrhea or vomiting.

• Delayed blood clotting: Omega-3 fatty acids can thin the blood, which might increase bleeding risks.

• Altered immune responses: Too much omega-3 may suppress immune function, which isn’t always beneficial.

• Imbalanced nutrient profiles: Over-supplementation with omega-3 while neglecting omega-6 disrupts the delicate fatty acid balance.

A 2013 study in the Journal of Veterinary Internal Medicine highlights these risks and concludes that omega-3 supplementation must be carefully dosed and balanced with omega-6 to avoid adverse effects (Lenox & Bauer, 2013).

This means feeding large amounts of omega-3 supplements without adjusting omega-6 intake or considering total diet composition can be counterproductive or even harmful.

Signs of Omega Fatty Acid Imbalance in Dogs

Understanding how fatty acid imbalances manifest can help dog parents notice early warning signs such as:

• Dry, flaky, or itchy skin: Commonly linked to insufficient omega-3s or excessive omega-6 fats.

• Dull or brittle coat: Lack of DHA and EPA may impair hair and skin conditioning.

• Joint stiffness or soreness: Increased inflammation worsens arthritis symptoms.

• Increased allergies or inflammatory flare-ups: Imbalanced fatty acids can exacerbate immune-mediated conditions.

• Poor cognitive function in puppies or seniors: Omega-3 deficiency impacts brain health.

Balancing the right amount of omega-3 and omega-6 helps prevent these issues and promotes healthier skin, joints, and immune resilience.

How Dog Food Quality Influences Omega Fatty Acid Balance

The source of fats in a dog’s diet heavily shapes omega-3 and omega-6 ratios.

Sources high in omega-6

Corn oil, soybean oil, sunflower oil, and animal fats from conventionally raised livestock typically have high omega-6 content.

Sources rich in omega-3

Marine oils like salmon oil, anchovy oil, or algae oils provide beneficial EPA and DHA.

Whole food ingredients and fresh meats usually offer a more balanced fatty acid spectrum compared to heavily processed foods laden with cheap vegetable oils.

Many kibble brands use inexpensive oils that inflate omega-6 ratios, though these products often list “omega fatty acids” on packaging, creating consumer confusion.
