Quick answer

For most dogs, a practical maintenance range is about 30 mg EPA+DHA per kg of body weight per day, while a common therapeutic range for skin or inflammation support is closer to 100 mg/kg/day. That is why dog weight matters so much.

10 lb (4.5 kg)~135 mg EPA+DHA/day~450 mg/day
20 lb (9 kg)~270 mg/day~900 mg/day

What this chart is good for

  • It helps you sanity-check a label fast.
  • It shows why many “one pump for every dog” directions are too vague.
  • It makes bottle value easier to judge before you buy.

What this chart does not tell you

  • It does not know the EPA+DHA concentration of your exact product.
  • It does not replace veterinary guidance for pancreatitis risk, bleeding disorders, or unusually high-dose plans.
  • It does not show pumps or milliliters unless you know the label strength.

Best next step

Use the fish oil dosage calculator for dogs to turn this chart into exact mg, ml, and pump amounts. If itchy skin is the reason you are dosing, pair that with best fish oil for dogs with itchy skin.
