When Do Labradoodles Stop Growing?

Labradoodles are versatile dogs, making amazing family and service dogs due to their affectionate and clever nature. 

If you are considering getting a Labradoodle, you might have several questions in mind, including how big these popular dogs get.

So, when do Labradoodles stop growing? The simple answer is that it largely depends on one major factor- the size of the parents and grandparents. However, other factors besides genetics can also affect a Labradoodle’s size to a lesser extent, including diet and exercise. 

Understanding the different growth stages of these wonderful canine friends will help you care for your Labradoodle pup correctly, from diet to exercise and training.

Proper care during crucial growth phases ensures your beloved pet develops into a healthy, happy adult!

Understanding Labradoodle Growth Stages

Before we get into how big Labradoodles grow, let us go over the different stages of growth they go through:

Neonatal (0-2 weeks)

The neonatal period is the first two weeks of a Labradoodle’s life. During this time, they depend on their mother for nourishment and warmth. They can not move, see or hear. 

Transitional (2-4 weeks)

As Labradoodle puppies enter the transitional period, they open their eyes and start moving around and exploring their surroundings.

Socialisation Stage (4-12 weeks)

The socialization stage is a critical time for Labradoodle puppies. They begin to engage with littermates and humans. 

Proper socialization and obedience training set the foundation for their future behavior and temperament. 

Juvenile (3-6 months)

At this point, Labradoodles experience a noticeable growth. They become more active and curious and need increased mental and physical stimulation.

Tailoring their diet and exercise regimen to support healthy growth and development becomes increasingly important here. 

Adolescent (6-12 months)

You will see continued growth and maturation of physical features. Continued training is vital during this period. Their energy levels will be high at this time to the point where they become hyperactive, requiring plenty of daily activities to channel their energy. 

They will also be obsessed with chewing and biting objects, so you must provide them with appropriate chew toys to avoid the destruction of our personal belongings.

Adulthood (1-2 years)

By the time Labradoodles become adults, they have typically reached their full height. But, they might continue to fill out and develop muscle tone. So, you must be careful about their nutrition and transition to adult dog food.

When Do Labradoodles Stop Growing?

There are typically three size ranges of Labradoodles, determined by the type of Poodle with which it mated. These include the standard, miniature, and toy Labradoodle. Each size has slightly different growth patterns, with smaller dogs like miniature Labradoodles reaching their full size at about 9 to 10 months and the larger breed continuing to grow till 24 months. 

On average, Labradoodles attain their full height at around 18 months, but a standard Labradoodle can continue to put on weight till its second birthday.

To give you a better idea, here are the approximate ranges for each size type:

Standard Labradoodle

Standard Labradoodles mature between 21-26 inches at the shoulder, and approximately 45-60 pounds

Medium Labradoodle

A medium Labradoodle can grow 17 to 20 inches tall and weigh 35 to 45 pounds, similar to a cocker spaniel. 

Miniature Labradoodle

A mini Labradoodle will grow up to 17 inches tall and weigh about 20 to 25 pounds at maturity.

Factors Influencing Labradoodle Growth

To determine your Labradoodle’s full size and help it reach its optimal size weight, you need to keep a few things in mind. 

Certain factors affect Labradoodle growth, which are as mentioned below:

Genetics and Parentage

Genetics plays the most significant role in determining how big a Labradoodle will grow. Depending on the size of the parents, and grandparents. 

Diet and Nutrition

Proper nutrition is essential for healthy growth in Labradoodles. A balanced diet that meets their needs at each stage of development ensures they receive essential nutrients for optimal bone, muscle, and organ growth. 

Understanding portion control, providing high-quality dog food, and keeping track of special dietary requirements will help your labradoodle grow to its full potential and as healthy as possible, avoiding conditions like stunted growth and obesity. 

Exercise and Activity Levels

Exercise and physical activity play a pivotal role in Labradoodle growth and development. 

Adjusting exercise routines to their age and energy levels supports muscle development, cardiovascular health, and overall fitness. Strenuous exercise at a young age can cause damage to their bones and joints, while too little exercise can also result in obesity, affecting overall size. 


The decision to neuter your Labradoodle can impact their growth plate closure. While neutering can prevent some health issues and unwanted behaviors, timing is crucial. Undergoing the procedure before sexual maturity can alter a male’s hormone levels, delaying its growth plate closure and causing it to grow taller than average, which could further cause joint issues.

That is especially concerning for Labradoodles as the breed is prone to diseases like hip dysplasia.

So make sure you discuss the right time to spay or /neuter your labradoodle to ensure their best health. 

Health and Veterinary Care

As with any dog breed, regular veterinary check-ups are vital for monitoring Labradoodle growth and addressing potential health concerns that may affect their development early on. 

Vaccinations, preventative measures, and early intervention for possible emerging issues contribute to their overall growth and well-being. That isn’t just something you should prioritize when your pup is young but throughout their life.

So, the full height and weight of a Labradoodle can vary greatly depending on their specific mix, genetics, and overall health. 

Female Labradoodles vs. Male Labradoodles

Many people wrongly believe that dogs are the same size regardless of gender. That is far from the truth. There are some noticeable differences between the two, especially in growth. 

Female Labradoodles

A female Labradoodle will generally mature slightly smaller in height and weight than their male counterparts. 

They typically reach their full height and weight between 12 and 18 months old. Note that females experience heat cycles every 6-12 months, which can influence their behavior and overall growth. These cycles may lead to temporary shifts in appetite and energy levels. 

Male Labradoodles

Male Labradoodles tend to be a little larger as they reach maturity. However, they also achieve their full height and weight between 12 and 18 months. 

Neutering may impact growth in male labradoodle dogs, so it is advisable to neuter them according to when the vet suggests it is best, which is typically after their first year.

I was afraid that my girl labradoodle was going to get to big but then I realized that I was consistently looking at male labradoodles. I definitely see a difference in size between the two genders.

Signs of Growth Plate Closure in Labradoodles

Growth plate closure is a natural process in a young canine’s skeletal development. Growth plates are areas of soft tissues present right at the ends of long bones. They are responsible for determining the final size and shape of the bones.

During growth, the growth plates gradually close as they harden into bone. This process typically occurs as the dog reaches maturity, signaling the end of active bone growth. Once the growth plates have closed, the bones can no longer grow in length.

As Labradoodles grow, some clear signs tell us their bones are ceasing to get bigger further. The following is what to look out for:

Steady Height

You will notice that your Labradoodle is not getting much taller. Their growth in terms of height slows down, showing that their bones are nearly at their adult length.

Slower Growth Rate 

Those super-fast growth spurts start to ease up. It is a sign that the bones are finishing their active growth phase.

Firmer Bones

When you touch your Labradoodle’s bones, they will feel more solid. That means the growth plates are closing up, and the fragile bones are developing into adult bones.

Less Joint Sensitivity

Your Labradoodle might not be as sensitive or tender in their joints during play and movement. That is a good sign that the growth plates are calming down and the joints are getting more stable.

Less Limping or Stiffness

After playtime or exercise, you will notice less limping or stiffness. That means the bones and joints are adjusting well to their adult size.

How to Ensure Healthy Growth in Labradoodles

As a pet parent, your primary responsibility is to care for your Labradoodle puppy in a way that ensures healthy growth. The following is what you must take care of:

Balanced Nutrition

A well-rounded diet with high-quality dog food is vital, especially during the first six months. Feed your pup at least four high-protein meals daily until six months old, after which you may feed them twice or thrice.

Portion Control

It can be hard to look at those puppy dog eyes and say no to another bowl of their favorite puppy food. Stay firm here and avoid overfeeding by following recommended portion sizes. 

Overfeeding can lead to rapid growth, potentially causing significant health issues like obesity and heart disease. Controlling portions will help ensure your Labradoodle maintains a healthy weight as they grow.

Regular Exercise with Caution

Exercise is puppy care 101, but you have to do it right. Engage in regular exercise appropriate for the age to promote normal muscle development and overall fitness. As mentioned, you must be cautious about excessive or high-impact activities, especially during the rapid growth phase, to protect developing joints.

Mental Stimulation 

Growth goes beyond developing physically. Dogs are intelligent and intuitive creatures. Regular play is at the core of keeping your dog mentally stimulated and maintaining their well-being. A bored dog can lose its appetite, affecting its growth. 

Therefore, engage your Labradoodle with puzzle toys, training, and interactive play to stimulate their mind and prevent boredom. That could be a chew toy, a ball, or even their favorite stick from a walk. 

How to Tell If Your Labradoodle Pup Is Growing Right?

Ensuring your Labradoodle pup is growing the right way involves keeping track of several key indicators. 

Here is how to tell if your Labradoodle pup is on the right track:

Consistent Weight Gain

Monitor their weight over time. They should experience steady, consistent weight gain without sudden spikes or drops. Consult your vet for specific weight milestones based on your furry friend’s age and breed so you can have a more accurate idea of how fast or slow your puppy is growing.

Proportional Body Development 

A healthy growing Labradoodle should have balanced body proportions. That means their head, body, and limbs should be proportionate to one another. If you notice signs of disproportionate growth, consult the vet immediately. Most of the time, rehab exercises can help bring the puppy back to standard labradoodle size.

Healthy Coat and Skin 

Whether you have a mini Labradoodle or a standard one, a shiny, soft coat and healthy skin are signs of good nutrition and overall well-being. If you notice dullness, dryness, or excessive shedding, it may be a sign that something is wrong, and you should consult your vet.

Energy Levels

A growing Labradoodle pup should have plenty of energy for play and exploration. They should be curious, active, and engaging with their surroundings. 

Energy levels might look different in a puppy compared to a grown labradoodle. Still, you should be able to tell if your puppy is being extra lethargic based on their temperament. They should grow just fine as long as their energy seems on par with the usual. 

The Bottom Line

Being a Labradoodle owner is a pleasurable experience. When buying a dog, a crucial consideration is how big the dog can grow. Simply put, a Labradoodle will stop growing at 24 months; however, it would have achieved its full height at around 18 months.
