Labrador puppy growth FAQ

The most commonly asked Labrador puppy growth questions are answered below

How much should my puppy weigh?

How much your puppy should weigh will depend on a number of factors

The genes he has inherited from his parents will go some way towards determining his final weight.

But this will also be influenced by his environment.  Including the time he spent ‘in utero’.

In addition,  it is impossible to predict which of his parents your puppy will take after in terms of size.   Brothers and sisters, even from the same litter, may vary widely.  In short, no-one can tell you exactly how much your puppy should weigh at any given age or stage.

What matters is what your puppy looks and feels like.   Your hands and eyes are the best guide to whether or not your puppy is getting enough,  or more commonly too much,  to eat.

When do Labrador puppies stop growing?

There is no exact answer to this question and there are a number of factors to take into account.  But as a general rule,  the substantial majority of your labrador’s  growth will be complete within the first eighteen months.

After the end of the first year,  much of the upward growth will be complete.

Your Labrador will  have almost reached his full height.

During the first half of his second year he will begin to fill out and look more mature.  He may put on quite a bit more weight but this should be muscle and bone, not fat.

How is growth rate affected

The growth rate of our Labradors is influenced by a number of factors.  You can to a certain extent (but should not) speed up a dog’s growth rate by overfeeding.   This kind of rapid growth is harmful and can lead to poor development of the hip joints.

Neutering can also influence growth rates as sex hormones are involved in the growth process.  Neutering before puberty may delay the closure of growth plates resulting in a taller dog.

 How big will my Labrador get?

The final size reached by your Labrador will depend on a combination of his genes (ie how tall his parents were,  and environmental factors such as nutrition, whether or not he is neutered, and his general health.

Labrador puppies which suffer serious illness for example,  or that are chronically underfed, may not grow to their full potential.

Does it matter if my Labrador grows too fast?

The short answer is yes.  Overly rapid growth is a bad thing.  If your Labrador is growing  too fast, even if he is not fat,  you need to have a chat with your vet and review your feeding schedule.  Slower growth is associated with better development of joints.

I am buying a pet carrier for a labrador that will be 9 weeks old when I get the dog. How tall is a labrador at that age.


Joanna Dean September 27, 2013 at 10:50 pm

He will still be very small.. Probably around 10lbs. I have a lab that is 6 weeks old and he is only 5 lbs.

I bought a 6 week older lab puppy yesterday and this is my first puppy too. He is playing for couple of min then go for rest and most of time he spend reting and when we are providing him food he is not eating it once. he eat some ammount of food and then lay down then eat some more and he is going for toilet too much. He seems a bit lazy or sad.

My lab puppy is 6 months old and 37.9 lbs. I just had her spayed and she was the runt of the litter. She is not too skinny, in fact she very healthy looking. But i’m wondering if she is just really small?? Can I get some opinions?


David S. December 22, 2013 at 2:29 am

My lab (Star) was only 5 lbs at 6 weeks old. She was the runt and was malnourished. She is 33 weeks old today and weighs 45lbs. She is a healthy, happy dog now. The vet is happy with her growth. Star weighed a little less than your dog at six months old. Not sure how big Star will get but she will not be a huge dog. She could still reach 70lbs when she is completely grown. You never know though, she could even end up weighing more

Hi, just discovered this old post and your comments. Our Bella is 33 weeks old and is about 46-47 pounds. She is about 19 inches at the withers. And, looks perfectly healthy, is full of energy,and absolutely wonderful. I am surprised to read references on the Net where people talk about their 5 month old being 50 pounds and such. Phew. Should we be bothered at all?

My female Lab is almost 20 weeks old and weighs almost 15 kilos. I wonder approx what weight gain is normal. She was putting on 1 kilo per week and has slowed down. Do they even out and then have a growth spurt later. I have put her on a RAW diet as the premium kibble was not agreeing with her. She looks healthy and happy, not too fat not too thin.
