6 frequently asked Labrador puppy growth questions


Some of the most commonly asked questions on this website are about growth.

We all want to know that our Labrador puppies are healthy and thriving.

And steady growth is one of a number of indicators of puppy health.

In this article we look at the most frequently asked questions on growth, and hopefully provide you with some helpful answers

1 How much should my Labrador puppy weigh?

This is the number one question asked by new puppy parents.  And it is a difficult one to answer accurately.
6 frequently asked question Labrador Puppy GrowthBecause Labrador puppy weight will vary widely depending on a number of different factors.

These include the genetic information passed down to him by his parents, and the environment he has been exposed to so far

You can find more information and a very rough puppy weight guide in this article:  How much should my Labrador weigh 

Because it is so difficult to know exactly what size your puppy will potentially be as an adult, no-one can accurately predict what he should weigh now.

So the weight guide can’t tell you exactly what your puppy should weigh today, or any other day, but it may give you an indication if your puppy is seriously under or overweight.

The very best guide  is how he looks and feels, and the article above will help you decide if your puppy is doing ok in this respect

2 How big will my Labrador get

Assuming that your puppy had healthy (not overweight) parents, their own weights will have some bearing on your puppy’s expected weight and height as an adult, and therefore on how much he weighs at different point on his journey towards adulthood.

Labradors from show lines are often heavier in build and bone, than Labradors from working lines, which tend to be more ‘racy’ in appearance.  You may find you need a bigger dog crate for example, for your bench bred dog, than your friend does for his field bred one.  But these are very broad guidelines, and within each type, especially working type, is a huge range of different sizes.

So no-one can predict your dog’s final size based on his parentage.  It may give you a rough idea, but there are always surprises in any group of dogs.

Your dog’s environment will also influence his growth rate and possibly his final weight as an adult.  Puppies that are overfed may grow faster than they should (and this can be harmful in terms of health).

Just like human infants, puppies that are chronically undernourished or that suffer serious illness in puppyhood, may never reach their full potential in terms of size.

3. When will my Labrador puppy stop growing?

Much of your puppy’s growth will be completed before he reaches his first birthday, and most Labradors are fully grown by about eighteen months old.

In fact, he will be quite close to his final adult height at around nine months of age, and a lot of his growth after this point will be ‘filling out’ rather than getting taller.

An important consideration is that the completion of ‘upward growth’ is the point at which your dog’s bones stop growing.

This is the time at which most experts feel it is safe for the dog to begin more strenuous activity, such as long runs and activities involving jumping, without damaging his joints.

4. How can I make my Labrador puppy grow taller?

We are asked this question surprisingly often.  Especially from our overseas visitors.  There is a conception that the taller the dog grows, the better!

This is definitely not the case.

Your puppy should grow at the rate his genetic potential determined and no more.  Excessive growth may bring its own problems, so don’t be tempted to increase his puppy food rations in order to make him bigger.

Neutering at an early age can affect the final height your dog reaches, because sex hormones influence the time at which bone growth slows down and without them bones may grow for longer.  But there are disadvantages to this lengthening of the bone growth period and wanting a taller dog is not a good reason to neuter him.

The best way to ensure that your puppy reaches his full potential height as a adult dog, is to make sure he is fed an appropriate and nourishing diet.  And is protected from accidents and illness where possible.

5. Does it matter if my puppy is a bit plump?

We all used think that puppy fat was a good thing.  When I was a child fat puppies were the norm and perhaps this extra layer of fat was helpful in sustaining the puppy during illness before vaccinations were widely available for dogs.

Nowadays, the thinking is that puppies should be slim.  With a defined waist, just like an older dog.

Overfeeding puppies doesn’t just make them roly-poly plump, it can speed up growth, and that may be a bad thing when it comes to joint health and other aspects of being a ‘well’ dog.

So yes, it does matter if your puppy is overly plump.  Reduce his daily rations a little until you start to see a waist appearing.  Ask your vet for advice if you are worried.

6. My dog weighs 35lbs at six months old. Is that OK?

This is the most common variation on the ‘how much should my puppy weigh’ question.  People post up their puppy’s weight and age, and want someone to tell them this is ok

I cannot stress too strongly, that it simply is not possible to tell you how much your puppy should weigh at any given age.

To illustrate how much very healthy puppies may vary, check out this thread in the forum  How much does your puppy weigh  

Here you will find lots of people have added their puppy’s weight at a given age.  The range and diversity of weights in Labradors is enormous.

Why not join in and add your dog?  The more dogs we have on the thread, the more interesting it becomes!

Your dog

Try not to worry about your puppy’s growth, or to weigh him too frequently unless you have cause for concern, or your vet has recommended it.

Enjoy your puppy for what he is, large Labrador or small.   And check with your vet if you think he is unwell or not growing as he should.

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.
    I may sound immature but he is my first so please give some suggestions

  4. Hi,
    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?

    • 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 lab just turned 7 months old 4 days ago . I had him neutered today he weighs 54 pounds and is 22 inches tall at the withers. I think your dog is on track. My dog had parvo at 8 weeks and has done amazing well.

  5. 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.

  6. Hi pippa

  7. Hi my female lab Always shouting at night time some one should be with her then only she has been slient. IT has any solution dog to be alone

  9. my lab is 2month old puppy but is cominng 24 hrs smeal in house. so kindly suggest how to going smeal. food is cantinue droo 3kgs small size type .

  10. Hey i am going to get a lab from my aunt 6months old i am curious to kown if he would be in a puppy category or no.

  11. We have a 14 week old male English Lab. He is very lazy. Sleeps a lot and when he plays, seldom runs. He is 27 lbs. He is constantly biting when he plays. Should we be concerned?

  12. My 10 month old chocolate lab is only 25kg and still looks like a puppy not nearly a year old! I asked the vet and she suggested maybe he is more of a black lab. Both parents were chocolate and 2/11 puppies were golden and rest chocolate. I read up on the genes for colours etc and i’m aware it is possible. Just wondered if anyone has had a lab like this and if they are late growers or he will always be puppy size lol he still has a lot of the lose skin/fur to suggest he has growing to do! We love him regardless obviously and adored how easy he was to train considering what people say about chocolates. He is smart, walks to heel, total recall and stays in sight, waits and crosses a road on command. Just as crazy as they are at other times though yet has the patience of a saint with my 2 year old and her dr’s set. Thanks for reading.

  13. My labrador is about an year old now. But he is still very slim and feeble as compared to other labradors I have seen. I’m worried about it. I don’t know if there anything that I’m not caring about? Kindly suggest me what do I need to do.

    • my 2/half year old lab is 68 .4 pounds. she is stocky. but vet says is in great health&shape. she had puppies with my dashound before i got her fixed. and her puppy looks just like her. had her fixed at 8 months she is 30 pounds.1 oz. and in great health. I believe its has to do with how much activity your dog gets. I live in county and Labs love to run. I keep there bowl full of food. And then only eat in the morning. Started that when they where babies. Labs eat a lot at first. I’ve never had a problem with over weight animals.

  14. My lab is 19inches tall and turns 6months on this Feb 8 and weighs around .approx 30-35lbs how to grow my dog taller, its diet is: 2x pedigree and 1x eggrice or chicken as veterinary suggest me…. It is 650+ grams per day more than it needs is it in its proper height and weight if not how can I increase it’d height and weight

  15. My yellow lab is about 9 months old.He is healthy n is very active but my concern is he is a bit skinny(thin) n height is 17 inch from shoulder n his head is also not so big.Is this normal.Is he skinny because he’s in his growing age? What should i do or feed to make him look big.And what’s the maximum height he’ll reach n how long will it take him to grow to the fullest.? Plz n e 1 reply.

  16. My female lab is 10 months old and she weighs 65 pounds. We have 2 other labs that are male and our oldest lab who is 9 she is about 2 hands shorter than him. How can I figure out if she was the runt of her litter?

  17. My lab is 11 months and she is 26,5 kg and 53 cm tall. She is very slim and for a long time I was worried about her growth. But most of the labs I see in my city they are overweight males so compared to them she is really tiny. Also, many dog food producers add growtg stimulators to food and puppy growth is artificially accelerated!

    From another hand every lab is growing st his own pace , these are not clones after all :-)

    So I stopped worrying and I am enjoying walks and companion of my beautiful dog every day. I stopped measuring her; I am not going to enter into any dog beauty contest as I think is useful only for those who want to earn money on dog breeding or for snobs who want to show off their champion ribbons …My dog is my best friend; she is not a show-off item. I only want her to be healthy and happy, same as she makes me so happy each day :-)

  18. Hi! We have a 4 month old yellow lab, we got her when she was 4 weeks old, cause her mom cannot feed them anymore, .. We are wondering why is she’s so small, her siblings are like half the weight ang height of their parents, and ours is still really small, it started noticing her growth delay when she had a deworming shot from our vet and got an allergic reaction.. Please, what can we do about her growth? We are so sad about her being small and left out with her siblings..

  19. hiii. guys
    i just saw Labrador puppy. his current owner want to sell them and he said the puppy age was 6 month old, puppy was to friendly and active but i saw his hair was falling i don’t know his owner providing me correct information or not some one suggest and tell me about Labrador hair falling information to purchase or not those dog????

    • Not sure about hair but doesn’t sound right. I would call a vet to check just incase the breeder needs reporting for the dogs sake. Even if you don’t take him / her.

  20. We have lab/mix.She is 15 weeks and 15 kilos!!Guessing she may be a big girl.She is the color of a lioness and and is lanky with longish slim legs. Really confused about her final adult appearance. Mom was a chocolae lab and Dad is a lab/shepard mix but we haven’t seen him. Vet says she is NOT fat so are continuing her current food and amount. Nice girl with brains and energy!!

  21. Hiii.., am from india I have a lab which is cross breed, now its of 16weeks its looking like lean, will there be any high changes in looking bcoz of cross breed. its always play with clothes. please can I know the solution for improving the growth and stop playing with the clothes. And can you tell me what are the changes that comes in cross breed compared to pure lab.

  22. My female pup is 2 weeks off 7 months, and yesterday she weighed 20.2 kg. She is about 19″ tall. she is bred to be a chunky girl, though I don`t think she will be overly tall, whereas my older girl at 3 years weighs in at a nice slim 26.9kg, and is on the tall side for a bitch.

  23. Our puppy likes to go outside but sometimes he will stop in the middle of the yard when we try to walk with him we think that he probably hasn’t developed full sight yet he is only 4 weeks old. When do puppies normally develop full sight?

    • How very sad to read that your puppy has been taken away from his mother at just four weeks old. This tiny baby should be in a cosy nest with his mother and siblings. Do contact your vet as soon as possible for full instructions on raising such a very young puppy, and please don’t try to walk him. He is far too young.
