Labrador Retriever Weight & Calorie Guide
Quick Answer
A healthy adult Labrador Retriever weighs 25–36 kg (55.1–79.4 lbs), according to the AKC breed standard. Puppies reach 50% of adult weight by 6–8 months and full weight by 14–18 months.

For puppies under 12 months. Enter your puppy's current weight and age to predict adult weight.
How the puppy weight predictor works
This predictor uses growth milestone data from Salt et al. (2017), published in Veterinary Record, which tracked the weight development of dogs across five size categories from birth to adulthood. By comparing your puppy's current weight against the expected growth percentage for their age and size category, we estimate their adult weight range.
Factors that affect adult weight
Genetics play the largest role, but nutrition, neutering status, and overall health also influence growth rate. Puppies fed excessive calories during rapid growth phases may exceed their genetic weight potential, while underfed puppies may not reach it. Large and giant breeds grow more slowly than toy and small breeds, reaching full size at 18–24 months rather than 10–12 months.

Labrador Retriever Health & Weight Management
Labrador Retrievers are America's most popular dog breed — and unfortunately, one of the most obesity-prone. A genetic study found that many Labs carry a mutation in the POMC gene that makes them feel constantly hungry. Their eager-to-please nature extends to eating absolutely anything offered. Excess weight accelerates hip and elbow dysplasia, increases bloat (GDV) risk in this deep-chested breed, and shortens lifespan by up to two years.
Exercise: Labs need 45–60 minutes of vigorous daily exercise — swimming, retrieving, long walks, and hiking. They are natural water dogs and excel at dock diving. A Lab without adequate exercise becomes destructive and obese. Mental stimulation through scent work and puzzle feeders helps channel their food motivation positively.
Feeding tips: Measure every meal with a kitchen scale — a "generous scoop" can add 200+ excess calories daily. Feed twice daily using a large-breed formula. Avoid exercising right before or after meals to reduce bloat risk. Limit treats to 10% of daily calories; replace biscuits with carrot sticks or apple slices.
Keeping your Lab at a healthy 55–79 lbs (25–36 kg) is the single best thing you can do for their joints and longevity. Use PawScale's calorie calculator for Labs to set exact daily limits, check body condition with our BCS assessment tool, and build a balanced meal plan with the feeding guide.

Weight Management Tips for Labrador Retriever
Breed-specific guidance backed by veterinary research
Ideal Weight Range
Males: 65–80 lbs (29.5–36.3 kg); Females: 55–70 lbs (25–31.8 kg). Per the AKC breed standard, Labs should be shown in “hard working condition” — well-muscled without excess fat.
Source: AKC Breed Standard via LRCObesity Risk
Labrador Retrievers carry the highest documented genetic obesity risk of any breed. Approximately 23–25% of Labs carry a POMC gene mutation (a 14-base-pair deletion) that disrupts satiety signaling — these dogs literally cannot feel “full.” Each copy of the mutation adds ~1.9 kg of body weight, and carriers have a ~25% lower resting metabolic rate. This is not a discipline problem; it is biology.

Formula: AAHA 2021 GuidelinesExercise Requirements
- Adult: Minimum 60 minutes daily; ideally 80–120 minutes of mixed activity (walking, swimming, fetch). Swimming is ideal — low-impact and naturally enjoyed by Labs.
- Senior: 40–60 minutes, split into 2 sessions. Prioritize swimming to reduce joint stress.
Breed-Specific Weight Management Tips
- Weigh food on a kitchen scale — cup measurements vary by up to 120 kcal between brands. Calculate grams using your food’s kcal/100g density.
- Replace 10–30% of kibble volume with green beans — this “Green Bean Diet” triggers gastric stretch receptors, partially compensating for the missing POMC satiety signal. See our feeding guide for portion adjustment tips.
- Use puzzle feeders or slow-feed bowls — Labs with the POMC mutation eat rapidly and regurgitate; slowing intake aids digestion and satisfaction.
- Count treats as calories, not gestures — a single commercial biscuit (50–80 kcal) can equal 5–8% of a Lab’s daily budget. Swap for baby carrots (~4 kcal each) or cucumber slices (~1 kcal).
- Test for the POMC mutation — if your Lab is Embark or Wisdom Panel tested, check the results. Mutation carriers need ~10–15% fewer calories than breed averages.
Health Risks of Obesity
- Hip & Elbow Dysplasia acceleration — excess weight dramatically worsens joint degeneration; Labradors already rank high for both conditions (OFA data)
- Osteoarthritis — obesity is the #1 modifiable risk factor; every extra pound increases joint loading
- Reduced lifespan — a landmark study showed Labs fed 25% below ad-libitum intake lived 1.8 years longer (Kealy et al., 2002)
BCS Quick Check
Due to the Lab’s thick double coat and muscular build, visual assessment is unreliable — you must use hands. Run flat palms along the ribcage: ribs should be palpable with light pressure (like feeling knuckles on the back of your hand). The chest is broad, so check the waist from above behind the ribcage — a “tuck” should be visible. Pay special attention to the area over the tail base; fat deposits here are an early obesity indicator in Labs. See our BCS chart for visual guides.
Male vs Female Labrador Retriever: Size Difference
Male and female Labrador Retrievers differ noticeably in size. Males are typically heavier and taller at the shoulder.
| Metric | Male | Female |
|---|---|---|
| Weight | 30–36 kg (66–80 lbs) | 25–32 kg (55–70 lbs) |
| Height at Shoulder | 57–62 cm (22.5–24.5 in) | 55–60 cm (21.5–23.5 in) |
| Ideal BCS | 4–5/9 | 4–5/9 |

Frequently Asked Questions
How much should a Labrador Retriever weigh?
The ideal weight for a Labrador Retriever is 25–36 kg (55.1–79.4 lbs). Weight can vary based on gender, age, and individual build. Use our calorie calculator above to get personalized feeding recommendations.
How many calories does a Labrador Retriever need per day?
A typical adult Labrador Retriever weighing 31 kg needs approximately 1454–1817 kcal per day, depending on activity level and whether they are neutered. Use our breed-specific calculator above for an exact number based on your dog's details.
Is my Labrador Retriever overweight?
59% of dogs are overweight, and most owners cannot tell just by looking. Check your Labrador Retriever's Body Condition Score (BCS) — if you can't easily feel their ribs or they have no visible waist from above, they may be overweight. Take our free 2-minute BCS assessment above to find out.
When does a Labrador Retriever reach full adult weight?
Labrador Retriever puppies reach 50% of their adult weight by 6–8 months and typically reach full adult weight by 14–18 months, according to AKC growth guidelines. Small breeds mature faster than large breeds.
What size crate does a Labrador Retriever need?
A Labrador Retriever typically needs a 42-inch crate based on breed size. Use PawScale's free crate size calculator for a personalized recommendation.
Does my Labrador have the POMC gene mutation that causes obesity?
About 23–25% of Labs carry a 14-base-pair deletion in the POMC gene that disrupts satiety signaling — these dogs literally cannot feel full. Each copy adds ~1.9 kg of body weight and reduces resting metabolic rate by ~25%. If your Lab is Embark or Wisdom Panel tested, check the results. Use our calorie calculator to adjust portions if your Lab is a carrier.
What is the Green Bean Diet for Labradors?
Replace 10–30% of kibble volume with steamed green beans to trigger gastric stretch receptors, partially compensating for the missing POMC satiety signal. Green beans add ~4 kcal per tablespoon — far less than kibble. Monitor weight weekly and adjust portions. Check our BCS chart to track progress.
How much should a 6-month-old Labrador weigh?
A 6-month-old male Labrador typically weighs 16–23 kg (35–51 lbs), while females weigh 14–20 kg (31–44 lbs). Labradors grow quickly in the first 6 months — avoid overfeeding to protect developing joints. Track growth with our Puppy Weight Growth Chart.
Why is my Labrador gaining weight so fast?
Labradors are genetically prone to obesity due to a POMC gene mutation that affects appetite regulation. If your Labrador is gaining weight rapidly, check their BCS with our free assessment tool and recalculate daily calories with our Calorie Calculator.
How much should an adult Labrador eat per day?
An adult Labrador typically needs 1,200–1,700 calories per day. Active or working dogs may need up to 2,000. Use our Feeding Plan tool to convert calories into exact food amounts based on your dog's specific weight and activity level.
