Factors Influencing French Bulldog Growth

The Ultimate Guide to French Bulldog Growth

There are several factors that can influence the growth of a French Bulldog, including genetics, nutrition, and physical health.


Genetics plays a significant role in the growth development of French Bulldogs. Certain gene variations inherited from parent dogs affect not only their physical appearance but also their overall health and lifespan.

Genetic disorders such as hip dysplasia, luxating patella, and respiratory issues can potentially hinder a Frenchie’s optimal growth. These genetic influences may cause your bulldog to be smaller or larger than average sizes.

Using genetic testing, we can estimate the possible size of a French Bulldog and prepare proper care plans for any health concerns that might arise during their growth period.


Adequate nutrition plays a crucial role in the growth and development of your French Bulldog. This goes beyond ensuring they are receiving enough calories each day. Feeding them a balanced, nutrient-rich diet allows their bodies to develop correctly, maintaining healthy fur, skin, and overall wellness.

It’s important to note that food allergies can lead to dermatitis conditions in French Bulldogs. To combat this issue, we recommend considering specialized diets such as limited ingredient or grain-free meals if allergies persist.

These diets provide all essential nutrients without causing irritation and inflammation related to allergy reactions. Additionally, medication prescribed by a vet might be necessary for managing persistent allergies effectively in French Bulldogs.

Physical Health

French Bulldogs require special attention to their physical health due to their susceptibility to various skin problems. This breed is prone to allergies, itchy ears, sweaty skin folds, and dermatitis.

Atopic dermatitis, caused by allergens like food, fleas, or pollen, is common in French Bulldogs. They are also prone to ear dermatitis (otitis externa), which can occur due to swimming or infections caused by bacteria or yeast.

The excessive skin folds and wrinkles in French Bulldogs make them particularly susceptible to skin fold dermatitis, leading to painful eyes and breathing difficulties. Moist dermatitis, known as hot spots, is another condition that can be triggered by allergies or irritations.

Finally, between 10 months and 12 months, French Bulldogs will typically reach their full-grown height and weight.

Birth to 2 Weeks

During the first two weeks of their lives, French Bulldog puppies are completely dependent on their mother for nourishment and care. They spend most of their time sleeping and eating, as they are still developing and growing rapidly.

Their eyes and ears remain closed during this period, but they have a strong sense of touch and can crawl around in search of warmth and milk from their mother. It is crucial that they receive adequate nutrition during this stage to ensure healthy growth and development.

3 Weeks to 12 Weeks

From 3 weeks to 12 weeks old, French Bulldog puppies experience rapid growth and development. During this time, their bodies become stronger as they gain weight and height. At around 3 weeks old, their eyes and ears start to open, allowing them to explore the world around them.

By the time they reach 4 weeks, they can be introduced to puppy food and start weaning off their mother’s milk. As they approach the 8-week mark, French Bulldog puppies become more active and playful, exhibiting their unique personalities.

Their muscles continue to develop as they learn how to walk steadily on all fours. By 12 weeks old, these adorable bundles of joy are well on their way to becoming mischievous little companions who bring endless joy into our lives.

4 Months to 6 Months

During the period of 4 months to 6 months, French Bulldogs experience steady growth. At this age, a typical Frenchie can weigh between 9 to 12 pounds. Their bodies are rapidly developing and becoming more muscular.

This is also the time when their bones continue to grow and strengthen. While they may not be fully grown at this stage, their growth rate starts to slow down compared to earlier stages of development.

French Bulldogs require proper nutrition during this crucial growth phase to support their development. It’s important to provide them with a balanced diet that meets their specific nutritional needs.

Regular veterinary check-ups are also essential during this period for monitoring your Frenchie’s overall health and growth progress.

7 Months to 9 Months

During the period of 7 months to 9 months, French Bulldogs continue their growth and development. They are now transitioning from puppyhood to adolescence. At this stage, they will experience a significant increase in size and weight as they approach their adult size.

Their bones and muscles continue to strengthen, contributing to their overall body structure. It’s important for owners to provide proper nutrition during this time to support healthy growth.

Regular exercise is also essential in order to keep them physically active and prevent excessive weight gain. Monitoring their health and consulting with a veterinarian is crucial during this stage of growth to ensure optimal development and address any potential issues that may arise.

10 Months to 12 Months

French Bulldogs experience significant growth and development between 10 months to 12 months of age. During this time, they continue to gain weight and height, gradually reaching their full size.

Standard French Bulldogs typically finish growing by the end of this period, with males weighing around 20-28 pounds and females weighing around 16-24 pounds. It’s important to note that smaller variations such as Micro, Teacup, Toy, and Mini French Bulldogs may reach their full size a bit earlier at around 8-11 months of age.
