📖 How It Works

Fish Oil for Dogs Explained

Fish oil provides EPA and DHA omega-3 fatty acids. The maintenance dose is approximately 20mg of combined EPA+DHA per kg of body weight daily.

Always check the EPA+DHA content on the label, not just total fish oil. A 1000mg capsule typically contains only ≈300mg EPA+DHA.

🔎 Label Tip

Look for EPA and DHA listed separately and add them together. "1000mg omega-3" is NOT the same as "1000mg EPA+DHA".
