When Is A French Bulldog Full Grown?. Are you part of the thousands wanting to know exactly the time they can consider their Frenchies fully grown?

If you answered yes to the above, this blog post will give you all the information you need.

After getting a puppy, neutering it, you worry about how they’ll grow and when they will stop growing. Even if you’ve had experience with dogs, you’ll want to know how large and fast your Frenchie will grow.

When Is A French Bulldog Full Grown?

French Bulldogs will continue to slowly fill out anywhere between nine and fifteen months of age. They are considered fully grown around 12 to 14 months old, but may continue to put on muscle until they are two years old.

Your French Bulldog puppy will undergo five phases of development:

  1. A baby’s first two weeks are known as the neonatal stage.
  2. 2 to 4 weeks of age is the transitioning period.
  3. The socializing period occurs between the ages of 3 and 12 weeks.
  4. The ranking stage is between the ages of 3 and 6 months.
  5. The adolescent stage occurs between the ages of six and 18 months.

Stage One: Neonatal (Birth to 2 Weeks)

During the first few months of life:

  1. Puppies are toothless, blind, and deaf.

When a baby is born, the senses of touch and taste are already present.

The puppy is mainly influenced by its mother. She’ll take care of their nutrition and keep them warm.

During this time, puppies will primarily nurse and sleep.

The Interim Period (2 to 4 Weeks)

  1. Their sense of hearing and smell will develop during the changeover time.
  2. Their eyes will begin to open, and they will continue to grow.
  3. The first signs of a puppy’s teeth will appear.
  4. During this time, puppies will begin to walk. When they are a few months old, they can stand up, walk, wag their tails, and even bark!

Mother and littermates have a significant impact on a puppy’s personality.

The Process of Integration (3 to 12 Weeks)

As the name suggests, this is critical for a puppy’s socialization and quick growth.

Highlights of the socializing phase include:

During the first three to five weeks of a puppy’s life, they learn about the world around them.

Puppies get bladder and bowel control in the third to fourth weeks of their lives, and this is the point at which they begin to learn the need to first exit their sleeping quarters before going potty.

At 3 to 6 weeks of age, pups begin learning to be friendly with their littermates and other canines, such as playing and biting. Besides learning how to converse effectively with other dogs, puppies also learn about their social limits and how to enhance their physical coordination.

Puppies build emotional relationships and bonds with the people around them as early as the fourth week. Meet your future dog while it’s still cool.

When a puppy is 5 to 7 weeks old, they require a lot of good human engagement.

Puppies should begin vaccines between 6 and 8 weeks (source: American Kennel Club).

Puppies begin eating solid food around week eight, when they completely stop drinking their mother’s milk. Pups are ready to leave their canine birth family and move to their new human homes once they are fully weaned.

A puppy can begin potty training when it is 7 to 9 weeks old.

When pups are 9 to 12 weeks old, they can learn basic commands as they pay more attention to their owners (their new parents).

Every day, take your French Bulldog out for a walk. Your puppy’s socialization stage might be regarded as the first 14 to 16 weeks of his life. Nevertheless, you should continue to provide new experiences and environments for your dog during this time.

Stages of Evaluation (3 to 6 Months)

  • French Bulldogs begin teething at this point. It’s going to last for a long time.

It’s important to remember that your dog looks up to you as the primary authority figure in his life.

The Period of Adolescence (6 to 18 Months)

Adolescence marks the culmination of a person’s growth:

Puppies achieve sexual maturity between the ages of 6 and 9 months.

Your puppy’s growth slows down between 9 and 12 months. French Bulldogs typically mature between the ages of 9 and 12 months.

When a French Bulldog reaches one year of age, it has reached its adult weight and height.

Height and weight are not uniformly distributed.

Use the lighter weights for smaller Frenchies and females and the higher ones for males and bigger pups.

Due to the variety of French Bulldogs’ sizes and shapes, the estimated height and weight can vary. Based on breed criteria, this chart is shown below.

However, some Frenchies fall outside this criterion. Having a Frenchton or a half-breed French Bulldog means that its parents’ breed characteristics will influence your dog’s size.

On the other hand, mini or teacup French Bulldogs are the outcome of breeding little-sized French Bulldogs.

When Is A French Bulldog Full Grown?

The growth of a French Bulldog slows down around the age of six months, as can be seen in the growth chart. However, they will still put on some weight until they’re full-grown at roughly 9 – 15 months. When they’re approximately 9 to 12 months old, they’re about as tall as they’ll ever be.

Is My French Bulldog Overweight?

You may establish if your French Bulldog is overweight by noting the following:

  • Place your hands on your Frenchie’s ribs and feel them. The ribs should be palpable but not visible.
  • A dog’s shape should be more like an hourglass and less like an oval.
  • Even though Frenchies may struggle to breathe due to their Brachycephalic breed (short muzzles can induce obstructed breathing), healthy weight canines should be able to walk for a few minutes without issue.
  • If your Frenchie has those adorable rolls that most of us adore, it’s probably obese.

Of course, the best approach to find out if your French Bulldog is overweight is to obtain a second opinion from your veterinarian.

How Do I Help My French Bulldog Lose Weight?

The best method to keep your Frenchie at a healthy weight is to give him enough exercise, feed him food rich in protein, fat, fiber, and water, and stick to the serving size recommended on the nutrition facts label.

Your dog’s weight can be maintained by feeding it a diet rich in natural, high-quality components like this.

Keep in mind the 10% rule when rewarding your pet. Only 10% of your Frenchie’s daily calorie intake should be dedicated to treats, and French Bulldogs, for example, should eat roughly 25 calories per pound of body weight each day.

In other words, if your dog is 20 pounds and eats 500 calories daily, its daily snacks should be 50 calories. Apples and carrots are both healthy and delectable snacks.

Is My French Bulldog Underweight?

Hair loss, altered feces, and a lack of energy are signs that a dog isn’t getting enough nutrition. Your Frenchie’s ribs should not be visible, but you should be able to feel them. If your dog’s ribs are apparent, they may be underweight.

Can I Help My French Bulldog In Gaining Weight? 

Overfeeding can harm the health of our furry family members. A dog’s joints, heart, and lungs can suffer if it develops too much fat instead of lean muscle and good fats.

Consult your veterinarian if your French Bulldog appears underweight or is otherwise malnourished, as indicated by the French Bulldog growth chart. Some possible reasons one isn’t interested in eating include nervousness, unappetizing food, or dental concerns.


You can use the French Bulldog growth chart as a helpful reference, but don’t be frightened if your pup doesn’t precisely follow the chart. The size of a dog breed can vary widely and is difficult to estimate because of the influences mentioned above (genetic, dietary, activity, and health).

Whatever the exact size of your lovely French Bulldog, they all have a tremendous personality!
