When Are French Bulldogs Fully Grown? Growth Milestones Explored

French bulldogs are fully grown around 12 to 18 months old. During this time, you can expect them to reach a height of 11-12 inches and a weight of around 16-28 pounds. It’s important to note that every dog is unique, and some Frenchies may take longer to reach full size. Proper nutrition and exercise can also play a role in a French bulldog’s growth and development.

Do you have a French Bulldog puppy? They are truly adorable, with their bat-like ears and compact bodies. But when will your furry friend be fully grown? As it turns out, French Bulldogs reach maturity at around 12 to 18 months old.

In this article, we’ll explore the factors that impact growth rate, common growth stages, signs of full growth, health considerations during growth and how to prepare for adulthood. So if you’re wondering when your pup is going to stop growing, read on!

You may already know that different breeds grow at different rates. Some puppies can take up to two years to reach their full size while others may mature sooner than expected. This is also true for French Bulldogs; they usually reach their final weight somewhere between 12 and 18 months of age.

However, there are several other factors that can influence the speed of their development such as diet and exercise habits. Read on for more information about how these things affect your pup’s growth!

French Bulldog Growth

You’ll be amazed to see how quickly your pup grows and matures in just a year and a half! French Bulldogs typically reach their full size between 12 and 18 months old, although there can be some slight variation. Usually, they will continue to fill out until the age of two.

Generally speaking, males are larger than females but both can range from 11-13 inches tall at the shoulder when fully grown. To ensure that your Frenchie achieves optimal growth, you should focus on meeting their exercise needs and ensuring that all nutrition requirements are met.

Exercise helps build muscle mass so it’s important for them to get ample physical activity every day. Make sure to provide plenty of toys for playtime as well as regular walks or trips to the park. It’s also important to feed them quality food in appropriate quantities throughout their life stages—puppy food until 6 months followed by adult formula after that.

Various other factors can impact a French Bulldog’s rate of growth including environmental conditions, genetics, health status, and early socialization experiences. Whether fostered or adopted from a rescue group or purchased from a breeder, puppies may have different levels of exposure which could influence their development rate.

Genetics plays an important role too—smaller parents often produce smaller pups while larger parents tend to yield bigger dogs overall. Additionally, if your pup is unwell then this could slow down their progress and stunt their growth potential due to poor nutrition intake during crucial developmental periods such as puppyhood or adolescence.

Socializing your pup in an appropriate way is also essential for proper development so aim for short playdates with other dogs at home or in public areas like parks where they can learn canine etiquette safely under supervision.

Factors That Impact Growth Rate

Knowing the factors that impact growth rate can help you determine when your pup will reach its adult size. Genetics plays a key role in how fast a French Bulldog grows, as different dogs have different genetic makeup. For instance, some may be genetically predisposed to grow larger or faster than others.

Additionally, diet quality is another factor that impacts a French Bulldog’s growth rate. A nutritious and balanced diet of high-quality food helps ensure your pup gets the vitamins and minerals it needs to grow into adulthood.

Environmental factors also play an important role in determining a French Bulldog’s growth rate, such as temperature and exercise levels. If the environment is too hot or cold for them, their growth rate can be affected due to difficulty regulating body temperature. Exercise also helps maintain proper muscle tone and health, which can influence how quickly they grow into adulthood.

Health conditions can also affect a dog’s growth rate if left untreated or managed improperly. Common issues like parasites, joint deformities, respiratory problems, and heart defects can all lead to stunted development if not addressed quickly enough by your vet. Additionally, puppies who suffer from poor nutrition or lack of socialization during early life stages may experience slower physical development later on in life as well.

It’s important to take all these considerations into account when monitoring your puppy’s growth trajectory in order to best assess when they will reach their full-grown size. With regular check-ups at the vet and careful observation of their behavior and overall health at home, you’ll know exactly what steps to take in order for them to reach maturity safely and comfortably!

Moving on from here, we’ll discuss common growth stages of French Bulldogs more closely…

Common Growth Stages

As your pup progresses through its growth stages, you’ll observe changes in size and behavior as it matures into an adult canine companion. French Bulldog puppies will typically hit their growth milestones between 12-18 months of age. During this period, there are some distinct stages of development they go through:

The first few weeks:

  • Puppies should be fed frequently throughout the day to ensure they’re getting enough nutrition for proper growth and development.
  • It’s important to spay or neuter your French Bulldog before six months old, as this helps with controlling population numbers and also reduces certain health risks associated with unaltered dogs.

From three months to one year:

  • Weight gain and muscle mass increase significantly during this stage due to increased physical activity and calorie intake.
  • Your puppy’s coat becomes fuller, thicker, and more luxurious over time as he continues to mature.

At around 12-18 months of age, most French Bulldog pups have reached their full adult size, but they may still be growing taller until two years old. They may also continue to fill out musculature and add weight until approximately two years old or longer depending on diet and exercise levels.

While physical appearance is a key sign of maturity in adulthood, there are other signs such as mental maturity that will indicate when your pup is fully grown.

Signs of Full Growth

Once your pup reaches its full size and strength, you’ll know it’s reached the peak of canine maturity, symbolizing a bright future ahead.

While French Bulldogs reach their full height by 12-18 months old, there are signs that can indicate when they have finished growing. Spaying or neutering at the right time can help to ensure that your pup won’t experience any growth spurts after this age. Additionally, following good breeding practices is important to promote healthy growth and development for your Frenchie.

One sign that indicates when a French Bulldog has fully grown is when they have stopped gaining weight. Gaining too much weight can be an indicator of overfeeding, which can lead to health complications such as obesity and joint problems later in life.

Another sign to look out for is if the puppy’s coat has become glossy and thick instead of fluffy and thin: this means their fur has hardened into adulthood. If you notice these changes alongside your pup reaching the average adult size for its breed, then it’s likely they have grown into a mature dog.

Additionally, once a French Bulldog has reached its full size it will no longer require puppy food formulated specifically for growth; instead, opt for food designed for adult dogs with higher protein content to maintain muscle mass and energy levels throughout the day.

You may also find that your buddy’s energy levels increase slightly once they reach adulthood; make sure to provide them with plenty of exercise opportunities like doggy daycare or agility training so they can burn off some excess energy!

On top of all this, there are some health considerations during growth due to their short snouts making them prone to respiratory issues like brachycephalic airway syndrome (BAS). It’s important to keep an eye on your Frenchie’s breathing during active playtime to ensure that BAS doesn’t develop further down the line.

Health Considerations During Growth

Looking out for your Frenchie’s respiratory health is important, as brachycephalic airway syndrome (BAS) affects over 70% of French Bulldogs. This is due to their short noses and narrow tracheas, which can cause difficulty in breathing.

To avoid this, it’s important to monitor your French Bulldog’s exercise needs and provide them with proper nutrition during their growing stages. Exercise should be moderate and not too strenuous for young puppies since their bones are still developing.

Longer walks should be avoided, as well as physical activities that involve jumping or running up stairs. Instead, shorter walks with plenty of breaks will help the pup build strength without overexerting themselves.

It’s also important to keep a close eye on temperature changes; when temperatures outside drop below 40 degrees Fahrenheit, it’s best to limit outdoor activity until the weather warms up again. Nutritional needs vary depending on age; smaller meals throughout the day are ideal for puppies who are still growing and developing rapidly.

The meals should contain quality proteins along with fruits and vegetables that are high in antioxidants and fiber for optimal health benefits. Avoid unhealthy fats such as those from processed foods or animal by-products; instead look for healthy sources like olive oil or coconut oil that will give your pup more energy without causing weight gain or other health issues down the road.

Consulting a veterinarian can help you determine what type of diet is best suited for your Frenchie’s unique needs during its growth period so they can stay fit and active while avoiding any potential health problems associated with BAS later in life. With careful monitoring of exercise needs and nutritional requirements, you’ll ensure that your pup reaches adulthood feeling happy and healthy!

Preparing for Adulthood

Once your Frenchie has reached their full growth potential, it’s time to start preparing them for adulthood.

Exercise needs will change as they age, and a good exercise routine should be established at this point.

Socialization habits should also be developed, ensuring the puppy is comfortable being around people of all ages and sizes.

It’s important to make sure that your French Bulldog is accustomed to basic obedience commands such as come, sit, stay, and lay down.

Working with a professional dog trainer or enrolling in an obedience class can help ensure success when teaching your pup how to behave properly.

Your Frenchie should also learn how to walk on a leash without pulling or tugging – this will ensure enjoyable walks together!

Grooming is another important aspect of adult French Bulldogs’ health maintenance.

A regular brushing routine should be started early on; short-haired breeds like the French Bulldog are low-maintenance but still require weekly brushing and occasional baths to keep their coat healthy and shiny.

Nail trimming may also become necessary over time; if you’re not comfortable doing it yourself, enlist the help of a groomer or vet tech who can show you proper technique.

Training sessions are key during this period of development; it’s essential that puppies learn acceptable behavior early on so they don’t develop bad habits later in life which could be challenging to correct.

Rewarding positive behaviors with treats helps reinforce desired behaviors while discouraging unwanted ones – ultimately leading to well-mannered adult dogs!


You’ve learned a lot about the growth of French Bulldogs! It’s important to remember that every pup is unique and their individual growth rate will vary.

However, most pups reach full maturity between 12-18 months old. As your pup grows, be sure to keep an eye on their health and provide plenty of exercise and nutrition.

With the right care, your pup can reach its full potential and be the companion you always dreamed of having! So what are you waiting for? Go out there and get your very own French Bulldog today!
