Nordic Naturals Omega-3 Pet delivers concentrated EPA and DHA from purified fish oil, formulated specifically for large to very large dogs. These omega-3 fatty acids support healthy skin and coat, joint mobility, and cardiovascular and cognitive function in larger canine breeds requiring higher-dose supplementation.
Why It's Worth Considering: Nordic Naturals uses triglyceride-form fish oil, the form closest to how omega-3s occur naturally, which supports efficient absorption compared to many ethyl ester alternatives. The product is third-party tested for purity and oxidation levels.

More category questions
How much fish oil should I take daily?
For general health, 1-2g of combined EPA+DHA daily. For therapeutic use (triglycerides, inflammation, mood), 2-4g combined EPA+DHA. Check the label for EPA+DHA content per serving — many fish oils have only 300mg per 1000mg capsule, requiring 6-8 capsules for a therapeutic dose. Concentrated formulas provide 600-900mg per capsule.
What is the difference between EPA and DHA?
EPA (eicosapentaenoic acid) is primarily anti-inflammatory — best for joint pain, cardiovascular health, and mood disorders. DHA (docosahexaenoic acid) is structural — it comprises 40% of brain polyunsaturated fats and is critical for cognitive function, eye health, and fetal development. Most people benefit from both; higher EPA for inflammation, higher DHA for brain health.
Does fish oil cause fishy burps?
Low-quality fish oil can cause fishy aftertaste and burping. Solutions: take with food, choose enteric-coated capsules, refrigerate the bottle (slows breakdown), or use a concentrated triglyceride-form fish oil (higher quality = less burping). If you still experience burps, the oil may be oxidized — check the expiration date and smell the capsule.
Is krill oil better than fish oil?
Krill oil has better absorption per gram (phospholipid form) and contains astaxanthin (antioxidant), but it's significantly more expensive per mg of EPA+DHA. For therapeutic doses (2-4g EPA+DHA), fish oil is more practical and cost-effective. Krill oil is a good choice for general wellness at maintenance doses.
Can I take fish oil with blood thinners?
Fish oil has mild blood-thinning properties. If you're taking warfarin, aspirin, or other anticoagulants, consult your physician before starting high-dose omega-3. At standard doses (1-2g), the risk is low, but your INR may need monitoring. Stop fish oil 1-2 weeks before scheduled surgery.
How do I choose a quality fish oil?
Look for: third-party tested for heavy metals and oxidation (IFOS 5-star rated), triglyceride form (not ethyl ester), high EPA+DHA per capsule (600mg+ combined), and molecular distillation for purity. The Gabriel Score evaluates all of these quality signals automatically.
