What Age Do French Bulldogs Stop Growing?

French Bulldogs are a breed that tend to stay pretty small throughout their lives. They grow very quickly, and most Frenchies won’t reach full adulthood until they’re between 1 and 3 years old. However, this creates a lot of problems for many French Bulldogs owners who don’t know when their Frenchies will stop growing. This article will go over what age is considered to be the end of growth for this breed, as well as some tips on how to keep them fit and healthy throughout their adult life.

Thanks for jumping onto this article. Continue reading to learn more about Frenchies. 

Note – Throughout the article we are giving the average and scientific growth charts that research found to be average. These dogs can grow to be shorter or taller than what will be mentioned. 

When Does a French Bulldog Grow to Their Full Size?

Let’s jump in right to the main question and answer. Most of French Bulldogs grow to their full size in the first nine – twelve months. They will grow fast, and in a short period of time they will measure up to 1 foot tall. However, 3 feet standing upright. Frenchies, like almost every other dog breed, grow at a certain rate. However, what makes Frenchies one of the most dramatically growing dog breeds is the fact that they grow twice as fast as most other dogs. This is why, by the time they’re 1 years old, they’re already full-grown adults.

Why Do French Bulldogs Stop Growing?

That’s just how they are. It’s their genes and overall breed. After the age of 1, most of them will stop growing. There’s a myth that kids shouldn’t feed their dogs too many treats, or they’ll stop growing, but this is completely untrue. Frenchies are a very active breed, and they are prone to overeating since they have a very sweet tooth. Because of this, they’re more likely to get overweight than other breeds. Frenchies will stop growing in height after a year old but they can gain weight.

How Tall Will A French Bulldog Get?

The average French Bulldog will be at a height of ” 11 – 13″ inches or (27 – 33cm). Which if rounded is near 1 foot tall.

The height depends on the dog. Some Frenchies will grow a little bit taller than this, and some will be a little bit shorter. It’s important to note that there’s no clear line that shows when a French bulldog will stop growing. They might stop growing when they’re 12 inches tall, 13 inches tall, or even taller than that. There are many factors that can affect how tall a French bulldog will be, the main ones being their diet, genetics, and environment.

When Are French Bulldogs Fully Developed?

This is something that most people don’t think about. How old a French bulldog is doesn’t have anything to do with how tall they are or how much they’ve grown. A French bulldog can be 6 months old and still be a puppy, but when they reach the age of 1.5 years, they’re considered fully developed.

Being a puppy and an adult is different than growth height. By fully developed we mean fully mature and at the point when you can consider them as your adult frenchies. 

What Affects A French Bulldog’s Growth?

There are many things that can affect how quickly a dog will grow, and how tall they’ll end up being. However, what makes Frenchies one of the most dramatically growing dog breeds is the fact that they grow twice as fast as most other dogs. This is why, by the time they’re 1 year old, they’re already full-grown dogs.

Outside factors such as diet, health, and exercise play a big role in their growth. In terms of both weight and height. The biggest factor of course is genetics which we can’t alter and have an effect on. 

Let’s go over these one by one.

Diet Factor

Frenchies are a very active breed, and they are prone to overeating since they have a very sweet tooth. Their diet plays a big role in terms of their growth. A healthy diet equals a  healthy and stable growth. By feeding them the necessary nutrients they will get the most out of their height. On top of this, they also have a unique digestive system that is prone to a lot of issues, which is why they have to be on a specialized diet. The diet of Frenchies is very similar to that of other Bulldogs. They like to eat a lot of raw food, so you’ll need to feed them a lot of fruits, vegetables, cheese, bread, etc.

Make sure they don’t lack food!

Health Factor

The health of a French Bulldog is a bit different than it is with other breeds. First of all, they are one of the few dog breeds that are prone to obesity, and they’re also at a much higher risk of developing diabetes. However, they aren’t the most likely to get sick, and they aren’t very likely to have any significant genetic issues, either. Some of the issues that are more likely to affect them are:

• Hip dysplasia
• Elbow dysplasia 
• Patellar luxation
• Luxating patella
• Cruciate ligament rupture 
• Bloat

Genetics Factor

Genetics we all know what they are, don’t we? It’s something we can’t alter or have an effect on but it does affect us. If you’re French Bulldog has large parents you can expect them to end up around the same size as them. That goes for smaller ones to. 

Before we sup up. Here’s a cute video of a Frenchie growing.
