Labrador Puppy Behavior and Growth Stages

Labrador retriever puppies do plenty of growing, learning, and maturing in a short amount of time, especially when compared to humans.

Labs also change quite a bit, both mentally and physically from even birth to 8 weeks, which would be around the time you would bring your new puppy home.

The following segment will give you an idea of what occurs in the different growth stages of your Labrador Opens in a new tab.retriever’s early life.

Newborn Labs

A Labrador retriever’s mother is pregnant with puppies for only nine weeks, not nine months like human mothers and they develop quickly as soon as they are born.

They are dependent on their mother for most things and although they have fur at birth, their mother keeps them warm because their internal thermostats have not begun to work yet.

Their mother only lets them alone for bathroom trips and to eat and drink while the puppies huddle together for warmth.

One Week


Although you probably won’t see your pup until 8 weeks, Labs grow rapidly and their weight may have doubled at this time.

Two Weeks


Newborn puppies cannot see or hear but by 2 weeks their ears and eyes should begin to open, allowing for hearing and sight.

Handling should begin with the breeder for their first introduction to socialization. Puppies will receive their first worming.

Three Weeks

Puppies will begin teething as teeth come in and some solid food will be introduced gradually.

Puppies can sit, stand, and trot about, a little unsteadily, at this time and even play with littermates, each developing their own personalities.

Four Weeks

Labrador puppiesOpens in a new tab. are becoming a lot more vocal and they are looking and acting more like dogs, wagging tails and playing with enthusiasm. They are eating more solid food but still drinking their mother’s milk.

Their mother who has kept everything clean until now is beginning to grow weary, so clean-up will now fall to the breeder. Puppies will receive their second worming.

Five Weeks

By 5 weeks the Lab puppy’s mother is beginning to wean them and they should be spending more time with people to become properly socialized pups. Mothers also teach pups not to bite so hard when feeding and playing.

Six Weeks

Worming will take place for the third time. Puppies are eating all solid food about six times a day and are totally weaned.

Their mother still works with them in regards to biting and gives them a sharp bark, or reprimand, when they play too roughly with littermates.

Seven Weeks


Puppies will be socialized more, often with breeders beginning initial housebreaking. Usually, puppies will be checked out by a veterinarian before leaving their mother, brothers, and sisters for their new home at 8 weeks.

Eight Weeks

At 8 weeks, you will be picking your Labrador retriever puppy Opens in a new tab.up at the breeder’s and taking them to their new home.

Potty training and socialization should continue. Even though your pup was checked out by a veterinarian, you will need to make an appointment to begin the necessary vaccinations.

Before bringing your new puppy home, make sure you have all of the necessary supplies for the pup such as bed, blanket, crate, toys, dishes, food, treats, collar, and leash.

Keep in mind that this is the first time puppy has been away from their mother, littermates, and their familiar home.

Have patience and give them reassurance and love. They may cry or be shy or fearful until they feel comfortable in their new home.

Nine Weeks


Your Labrador puppy should feel more familiar with its surroundings. Keep on top of housebreaking, taking them out every 20 to 30 minutes, especially after meals.

Work on some basic training but keep sessions short. Socialization will be your biggest task now.

Take them to as many places as you can so they can see situations as an adventure, not something to be feared.

Ten Weeks

Your puppy will need more vaccinations and their veterinarian will check them out and their weight to ensure that they are growing properly.

Bathroom trips should be less frequent because they will hold “it” longer, but there will be an occasional accident. Keep working on socialization.


Three Months


At this time, your pup’s meals will be down to three a day instead of four and they should be totally immunized allowing you to enroll them in puppy classes, good for training as well as socialization.

By this time your pup should be properly socialized, but continue to take them to as many places as you can.

Four Months

You should be diligent with training because between 3 and 4 months is known as your retriever’s “juvenile” stage.

They may act independently and test you by ignoring certain commands that they are very familiar with. Be firm.

Five Months


Your puppy may be totally housebroken by this time and able to be left alone a little longer without accidents. Don’t fret, however, if they aren’t. Some pups take a little longer just as children may for potty training.

Make sure to work with your pup with a collar and leash if you haven’t done so yet. They are beginning to be stronger and when they become too weighty, pulling on the leash will be a chore if not properly trained.

Six Months

Between 4 and 6 months your pup may try to challenge you or other family members. You and others must be the dominant forces in the family.

Your pup is also looking more like a dog, but keep in mind, they are still a puppy at heart. Meals can now be reduced to two times a day.

If they haven’t been spayed or neutered, speak with their veterinarian if you aren’t planning on breeding them.

Six to Eighteen Months

This time of life for your pup is their “adolescent” period. You will need to continue with training and obedience classes can be a huge benefit.

Your pup will be quite a lot of fun at this time with lots of energy, stamina, and exuberance but will also show some characteristics of a rebellious teenager which may be frustrating. Be patient, yet firm.

They may have the appearance of an adult Labrador but are without the maturity of one.

When is Do Labs Stop Growing?

Keep in mind that just as humans are individuals, so too are dogs and some may be full-grown at a certain age, while others may add a few more pounds after this time. Generally, a Labrador retriever will stop growing when they’ve reached one year and are considered fully grown.

Their full height, however, will be reached by nine months of age. They also may be fully grown at a year but aren’t fully mature until two years.

A full-grown Lab will range in weight from 55lbs – 75lbs for females and 64lbs – 85lbs for males.

Your Labrador retriever may grow to be large or be a smaller version. If at any time you are concerned about their weight, whether too little or too much, visit your veterinarian and have them weighed to see if they’re on track or if something is amiss. This helps to ease your mind.

Enjoy every moment with your Labrador puppy as they grow through the stages. They grow quickly and before you know it, you’ll wonder where those puppy days have gone!
