How big will my Labrador get?
A Labrador typically settles somewhere between about 25 and 36kg as an adult, with males generally landing at the heavier end of that range and females at the lighter end. Most of their height is reached by around twelve months, though many Labradors keep filling out in body condition for a good while after that.
Typical adult weight by sex
Male Labradors generally weigh somewhere in the region of 29 to 36kg fully grown, while females typically sit a little lower, around 25 to 32kg. Individual dogs vary noticeably either side of these ranges depending on build and how active they are.
Labradors are also one of the breeds most commonly associated with weight gain in adulthood, so a healthy adult weight is often more usefully judged by body condition — an easily felt waist and ribs — than by a number alone.
How their growth typically progresses
Most of a Labrador's height and skeletal growth is complete by around twelve months old, but the breed often continues filling out in muscle and overall body condition for a further six to twelve months beyond that as it matures into an adult shape.
Weighing a puppy regularly through the first year and tracking the trend against a growth chart gives a far more useful picture than a single reading, and your vet can flag early if growth looks unusually fast or slow for an individual puppy.
Labrador puppies often go through an awkward, leggy stage before their body fills out, which is entirely normal and not a sign of anything being wrong. Comparing photos every few weeks tends to show the change more clearly than day-to-day observation does.
Common questions
- How much does a male Labrador weigh?
- Adult males typically weigh somewhere between 29 and 36kg, though this varies with build and activity level. Your vet can tell you whether your dog's weight looks healthy for their frame.
- How much does a female Labrador weigh?
- Adult females are usually a little lighter than males, typically settling somewhere between about 25 and 32kg fully grown, though individual build and activity level both affect where a dog sits within that range.
- Are Labradors prone to weight gain?
- Yes, the breed is commonly associated with a strong food motivation and a tendency to gain weight easily, which makes portion control and regular exercise particularly important throughout adulthood.
- What's a healthy body shape for an adult Labrador?
- You should be able to feel the ribs easily under a thin layer of fat, with a visible waist when viewed from above. A vet or vet nurse weigh-in is the most reliable way to check body condition properly.
