Labrador Retriever Weight, Lifespan & Feeding Guide

The POMC gene variant found in a significant portion of Labradors affects the brain's satiety signalling. Affected dogs feel less full after eating, which makes them more food-motivated and more likely to gain weight on standard feeding amounts. This is not a behaviour problem; it is a biological one.

• Measure every meal by weight (grams), not by cup volume. Cups vary by up to 20% depending on how they are filled.
• Use the food calculator with "high activity" only if the dog genuinely works or runs daily. Most pet Labs are moderate at best.
• Check body condition score every 4-6 weeks, not just at annual vet visits.
• Treat calories count. A 30 kg Lab's daily budget is roughly 1,200-1,400 kcal. A single medium biscuit treat can be 50-80 kcal, which is 4-6% of the daily budget in one snack.

These are reference ranges for a standard dry kibble (approximately 350 kcal per 100g). Actual amounts depend on the specific food's calorie density, so always check the label.

For your Lab's exact numbers based on current weight and activity level:

Adult Labs typically need 80-100 minutes of activity per day. This should not all be walking. Labs benefit from a mix of structured exercise, free play, and mental work.

Puppies: Follow the 5-minute rule, no more than 5 minutes of formal exercise per month of age, twice daily. A 4-month-old Lab puppy should not run more than 20 minutes at a stretch. Over-exercise before growth plates close, typically 12-18 months for Labs, raises joint injury risk.

Senior Labs (8+ years): Reduce intensity before reducing consistency. Shorter, more frequent walks are better than one long session. Swimming is particularly useful for Labs with hip dysplasia, which is common in the breed.

Labs typically live 10-12 years, with a midpoint around 11 years. Using the lifespan calculator's large-breed framework, a Lab enters the senior stage at roughly 7-8 years in calendar age.

• Hip and elbow dysplasia: one of the most common large-breed joint conditions. Keeping weight in the ideal BCS 4-5 range significantly reduces joint load and pain progression.
• Obesity-related disease: overweight Labs have higher rates of diabetes, joint disease, and certain cancers. Weight control is the single highest-impact longevity lever for this breed.
• Exercise-induced collapse (EIC): a genetic condition in some Labs that causes collapse after intense exercise. Affected dogs need activity limits, not elimination of exercise.
• Cancer: Labs have above-average cancer rates compared to many breeds. Annual vet checks from age 7 onward are worth prioritising.

Senior care shift (from age 7-8):

• Switch to senior-formula food or reduce calories by 10-20% if activity drops.
• Increase vet visit frequency to every 6 months.
• Add joint supplements (glucosamine/chondroitin) if mobility changes are observed.
• Monitor drinking and urination changes; they can be early kidney or diabetes signals.
