Labrador Retriever Growth Chart
Labrador Retriever puppies follow a large-breed growth curve and usually approach adult weight between 14 and 18 months. The chart below compares estimated male and female puppy weight by age in lb and kg, while the calculator uses your puppy's current measurement to return an adult range.

Labrador Retriever weight by age
Typical male and female puppy weight ranges by age, available in lb and kg. Individual puppies may vary.
Most Labrador Retriever puppies approach adult weight around 18 months, although individuals may finish earlier or later.
These estimated ranges combine the breed's adult weights with a size-based growth curve. They are not measured breed-specific percentiles or health targets. Month labels are rounded approximations; use the week values for each row. How these weight ranges are calculated
Labrador Retriever Growth Stages
Understanding the typical growth stages helps you know what to expect as your Labrador Retriever puppy grows.
Neonatal
0–2 weeksPuppies are born with eyes and ears closed, relying entirely on their mother. Rapid weight gain occurs during this period.
Socialization
3–12 weeksEyes and ears open. Puppies begin to explore, play, and learn social behaviors. This is a critical period for development.
Juvenile
3–8 monthsRapid growth continues. Puppies become more independent, start teething, and develop coordination.
Adolescent
8–14 monthsGrowth rate begins to slow. Puppies reach sexual maturity and may test boundaries. Muscle mass develops.
Young Adult
14–18 monthsGrowth is nearly complete. Your puppy is filling out and approaching adult proportions.
Adult
18+ monthsYour puppy has reached their full adult size. Weight should remain relatively stable with proper nutrition.
Labrador Retriever FAQ
How much will my Labrador Retriever puppy weigh as an adult?
Most adult Labrador Retrievers typically weigh between 55 and 80 lb as a large breed. Males often fall in the 65–80 lb range, while females may finish lighter at 55–70 lb. Your puppy's current age and weight help estimate where they may land within that spread.
At what age is a Labrador Retriever fully grown?
Labrador Retrievers are large dogs that typically reach most of their adult weight between 14 and 18 months. Many Labs look adult-sized by one year but may keep filling out chest and shoulder muscle. Slight muscle or coat fill may continue briefly after height stabilizes, so weekly weigh-ins give a clearer picture than a single reading.
How accurate is a Labrador Retriever puppy weight chart?
Labrador Retriever weight charts reflect breed averages, not guarantees. Variation from field versus show lines is common, and American and English Lab types differ in bone and height. Treat estimates as ranges and track your puppy's trend over several weeks for better context.
My Labrador is 70–75 lb at 6 months. How should I estimate adult weight?
Do not simply double that weight to predict an adult size. First check the scale, lb or kg setting, and age entry, then use the calculator with the current measurement. Parent weights, sex, and individual build provide context, but this tool also uses a breed reference range, so an unusually large puppy may not fit its assumptions. A single weight cannot tell you whether your puppy is healthy. If you are concerned about the growth trend, discuss the measurements with your veterinarian.
Does this Labrador growth chart predict height as well as weight?
This chart estimates weight only. It does not predict shoulder height, body length, or head size, and weight values should not be converted into height estimates. A puppy's height and weight can change at different rates. Use the weight table to follow the weight trend rather than as a height chart.
Is my Labrador puppy underweight or overweight?
The chart estimates adult size, not health — it cannot say whether your puppy is under or overweight. A practical check is body condition: you should feel the ribs under a light layer of fat and see a slight waist from above. Labs gain weight easily, so compare several weigh-ins rather than one. If you are concerned, ask your veterinarian, who can assess body condition in person.
How much should I feed my Labrador puppy?
Feed a quality large-breed puppy food in measured meals, and adjust by body condition rather than appetite — Labs are famously food-driven. Keep growth steady instead of fast; rapid weight gain stresses developing joints. Ask your vet about portions and when to switch to adult food.
