How much fish oil should I give my dog?

For general wellness, 50–100 mg combined EPA + DHA per kg of body weight per day. For arthritis or skin issues, 100–150 mg/kg. For heart or kidney support, up to 200 mg/kg under veterinary guidance.

Can dogs have too much fish oil?

Yes. Excess omega-3 can cause loose stools, weight gain from extra calories, vitamin E depletion, and rarely altered platelet function. Stick to evidence-based dosing.

Salmon oil vs fish oil — what is the difference?

Salmon oil comes from a single source and is typically lower in EPA + DHA per ml. Fish oil blends from multiple species are usually more concentrated. Read the label for combined EPA + DHA mg per teaspoon.

How long until I see results?

Skin and coat improvements often appear in 4–6 weeks. Joint comfort takes 8–12 weeks. Be consistent, store properly (refrigerated, dark), and replace every 60 days once opened.

Why Omega-3s Matter

Three core benefits backed by veterinary research.

🌿

Anti-Inflammatory

EPA reduces inflammatory eicosanoids that drive joint pain, allergic skin reactions, and inflammatory bowel issues. Effects build up over 6–12 weeks.

🧠

Brain & Eye Support

DHA is a major structural fat in nerve cells and the retina. Critical for puppy development and senior cognitive health.

✨

Coat & Skin

Omega-3s reduce skin barrier inflammation and improve coat shine within 4–6 weeks. The fastest-visible benefit of supplementation.

The Dosage Math

Daily mg = body weight (kg) × condition factor

Wellness 50 · Skin 100 · Joints 125 · Heart 175 · Kidney 200 (mg/kg)

Source ranges: National Research Council recommendations, 2006 NRC report, and Bauer 2011 review of omega-3 dosing in canine clinical practice. Doses above 200 mg/kg should be supervised by a veterinarian.
