Omega-3 for dogs
A 20 kg dog on a 50 mg per kilogram target needs 1000 mg of combined EPA and DHA a day, a figure you can match to a capsule or pump label. Built for dogs, from your vet's target. Free in your browser.

Dogs convert plant omega-3 fats such as alpha-linolenic acid into EPA and DHA only modestly, so veterinary nutrition writes marine supplements as combined long-chain milligrams per kilogram of body weight rather than as millilitres of oil. This omega-3 for dogs calculator multiplies a strictly positive body weight in kilograms by a target milligrams-per-kilogram rate and returns the daily milligram total you can compare with a product label. Typical educational targets sit near twenty to fifty milligrams per kilogram for coat support and fifty to one hundred for joint protocols; you supply the target and the engine only scales it.
How daily omega-3 milligrams are computed from weight and dose rate
The identity behind omega-3 for dogs is a single product: daily long-chain omega-3 milligrams equal body weight in kilograms times the target milligrams per kilogram you choose. Companion-animal nutrition almost always writes marine oil this way because dogs convert alpha-linolenic acid from flax, chia, and many plant oils into eicosapentaenoic and docosahexaenoic acid only modestly, so the label number that actually scales is the summed EPA plus DHA milligrams, not the millilitres sitting in a pump or the generic fish-oil grams on the front of a bottle.
A twenty-kilogram dog at a fifty milligram-per-kilogram target therefore needs one thousand milligrams of omega-3 per day; an eight-point-five-kilogram dog at thirty milligrams per kilogram needs two hundred fifty-five milligrams. The dose rate must likewise be a strictly positive finite number of milligrams per kilogram per day. Optional output keys are omitted rather than set to null.
Rounding is to twelve decimal places so goldens stay stable across JavaScript runtimes without changing the arithmetic.
Where an omega-3 for dogs calculator earns its keep
Clinic discharge sheets and tele-nutrition forms use an omega-3 for dogs calculator so a weight from the last exam and a target the veterinarian already chose become one milligram number a caregiver can match to a capsule or pump. Rescue groups and boarding kennels keep the same arithmetic next to the supplement shelf because a toy breed at three kilograms and a mastiff at seventy kilograms must not share a one-pump-for-every-dog rule of thumb.
Classroom labs in veterinary nursing assign the identity so students see why milligrams per kilogram, not millilitres of oil, is the quantity that scales with body size from Chihuahua to Great Dane. Failed validation does not consume balance. The calculator does not replace a veterinarian, does not convert vitamin A or D that some oils carry, and does not split EPA from DHA: send the combined milligrams-per-kilogram target your protocol already uses.
What you can do with it
Discharge sheets after a clinic weigh-in
Turn the last recorded body weight and the veterinarian's omega-3 milligrams-per-kilogram target into a daily milligram total a caregiver can match to the bottle label.
Rescue and boarding supplement shelves
Stop sharing one pump across toy breeds and giant adults: scale the same protocol target by each dog's kilograms so the milligram dose follows body size.
FAQ
How is omega-3 for dogs calculated?
Multiply body weight in kilograms by the target omega-3 dose in milligrams per kilogram per day.
What milligrams-per-kilogram target should I enter?
This engine does not invent a clinical target. Everyday educational figures often sit near 20–40 mg/kg for coat support, around 50 mg/kg as a maintenance example, and 70–100 mg/kg in joint teaching tables. Use the rate your veterinarian or protocol already specified.
Does the calculator convert millilitres of oil or split EPA from DHA?
No. It returns combined omega-3 milligrams per day.
What happens if weight or the dose rate is zero, negative, or missing?
Zero, negative, NaN, and non-numeric values are rejected and are not billed.
Can flaxseed or other plant oils cover my dog's omega-3?
Not reliably. Dogs turn plant omega-3 such as alpha-linolenic acid into EPA and DHA only modestly, so the figure that matters is the combined EPA plus DHA milligrams printed on a marine supplement label.

How daily omega-3 milligrams are computed from weight and dose rate
The engine echoes the cleaned weight and dose rate, returns daily_dose_mg as the primary figure, restates the formula so a client can print the identity next to the answer, and names the method omega3_mg_per_kg. Weight must be a strictly positive finite number: zero, negative, missing, NaN, Infinity, and non-numeric strings fail with invalid_input naming the field, because a hollow dose from a bad scale reading is worse than an honest error.
Input contract, common milligram-per-kilogram targets, and errors
Everyday educational targets cluster around twenty to forty milligrams per kilogram for coat and general wellness support, around fifty milligrams per kilogram as a widely cited maintenance figure, and seventy to one hundred milligrams per kilogram when a protocol is thinking about joint or inflammatory support—those figures are literature-shaped hints, not a prescription this calculator invents. You still choose the target; the engine only multiplies. Weight is rejected above two hundred kilograms and the dose rate is rejected above five hundred milligrams per kilogram so a unit mix-up, such as grams typed as kilograms or millilitres typed as milligrams per kilogram, fails closed instead of silently overdosing the result. POST a JSON body with two required numbers. weight is the dog's body weight in kilograms; aliases include weight_kg, dog_weight, body_weight, and kg. dose_mg_per_kg is the desired omega-3 milligrams per kilogram per day; aliases include target, target_mg_per_kg, mg_per_kg, dose_rate, and omega3_mg_per_kg. Each field may arrive as a JSON number or as a numeric string. On success the body includes weight, dose_mg_per_kg, daily_dose_mg, formula, method, and a note that this is an educational milligram total, not a veterinary prescription and not a conversion from a specific brand's pump. Compare daily_dose_mg with the EPA and DHA milligrams printed on the product, not with the millilitres of oil, because concentrations vary by more than a factor of ten across veterinary and grocery bottles.
Where an omega-3 for dogs calculator earns its keep
Keep requests small, pin daily_dose_mg in continuous integration, and you get reproducible educational numbers for LMS plugins, edge workers, and spreadsheet add-ins without standing up a clinical information system.
Integration use cases
Veterinary nursing labs
Give students two weights at the same milligrams-per-kilogram target so they can verify by hand that daily_dose_mg is exactly the product of weight and dose rate.
