Therefore, we can conclude that a French Bulldog will be fully developed between 12 and 14 months of age but will continue to gain muscle until two years old.

What Factors Can Influence the Size of a French Bulldog?

French Bulldog Genetics

If you have not yet acquired a French Bulldog, it is important that you ask the breeder many questions to learn a little more about the parents of the dog you want to acquire. For example, it is important that you know the size of their parents, the difference in size with their littermates, etc.

This will give you an idea of ​​the maximum weight and height that your French Bulldog could reach, taking the growth charts we have put above as a reference.

French Bulldog Exercise

Both exercise and weight are related to each other. Generally, French Bulldogs do not require a lot of exercise during the day, but they still need to move a few minutes a day to stay fit and healthy.

These dogs love long walks but are not designed to endure them due to respiratory problems caused by their brachycephalic nature. Therefore, you could provide games as an alternative to exercise. That will not only make your bond with your dog stronger, but that will also help it maintain its proper weight.

French Bulldog Diet

Food is also an important factor in the growth of not only plants and babies but also dogs, in this case, French Bulldogs. An unbalanced diet could affect your pet’s natural growth.

If you feed it too much unhealthy food, it could be overweight (outside the range of the growth charts shared above). The opposite will happen if you give it food in small amounts.

The most advisable thing is to take it to the veterinarian so that he can check your French Bulldog, and based on the results, he will determine the best diet for your pet.
