🐾 Omega-3 for Dogs Calculator
Get a general estimate of daily omega-3 (combined EPA + DHA) fish oil support for a dog, based on body weight and wellness goal. Always confirm with your veterinarian before starting a supplement.
What this calculator estimates
Fish oil supplements provide the omega-3 fatty acids EPA and DHA, which are commonly given to dogs to support skin and coat health, joint comfort, and general wellness. This calculator scales a commonly cited combined EPA+DHA amount (in milligrams per kilogram of body weight per day) to your dog’s weight, using different reference ranges depending on the stated wellness goal.
How the estimate works
The calculator converts your dog’s weight to kilograms, then multiplies by a per-kilogram daily amount: roughly 40 mg/kg for general wellness, 65 mg/kg for skin and coat support, and 100 mg/kg for joint and mobility support, all figures commonly referenced in veterinary nutrition guidance. It also converts the milligram total into an approximate liquid fish oil volume, assuming a typical concentration of about 300 mg combined EPA+DHA per milliliter (this varies by product, so always check your specific supplement’s label).
These figures are general, educational estimates only, not a prescription or medical dosage recommendation. Omega-3 needs vary with a dog’s health status, existing medications, and the specific product used. Always check with your veterinarian before starting or adjusting any supplement, especially for dogs with health conditions or those on other medications.
