Labrador Retrievers run 55–80 lb and carry two nutritional red flags: bottomless appetite genes (POMC variants in ~25% of Labs) and joint-load arithmetic that makes every extra pound expensive.
| Item | Detail |
|---|---|
| Target weight | Males 65–80 lb, females 55–70 lb |
| Daily calories (adult, neutered) | 1,100–1,400 kcal — less than the bag chart says |
| RER × factor | RER = 70 × (weight kg)^0.75; ×1.6 for neutered adults |
| Joint nutrients | Glucosamine ~500 mg/day, chondroitin, EPA/DHA |
| Feeding rhythm | Two meals; bloat is uncommon but not impossible |
The calorie trap every Lab owner falls into
A neutered 70 lb Lab needs roughly 1,250 kcal/day — but the feeding chart on a typical premium bag calls for 1,600–1,800. That 400-kcal gap becomes 3–4 lb of fat per year, and Labs are genetically wired to never refuse it: the POMC deletion found in a quarter of the breed measurably increases food motivation. Weigh food, not cups (a “cup” varies 90–130 g depending on kibble), and body-condition-score monthly with our 9-point card.
Joints, protein, and the large-breed rules
Labs rank high for hip/elbow dysplasia, so calcium discipline during growth matters more than adult protein debates: large-breed puppy formulas cap calcium at 1.2–1.5% DM. Adults thrive on 24–28% protein from named sources — our detailed Lab guide walks the full growth curve, and the RER × factor calculator does the math for your dog’s exact weight.
FAQ
How many cups should a 70 lb Lab eat?
About 3 to 3¼ cups/day of a typical 400 kcal/cup kibble, split into two meals — but weigh the dog monthly and adjust by body condition, not the chart.
Do Labs need joint supplements?
Diet-level glucosamine helps marginally; the evidence is stronger for keeping the dog lean. Every 5 lb of excess weight multiplies joint load measurably.
