How Small Is a Frenchie Puppy?

French Bulldog puppies are an absolute bundle of joy, and they’re incredibly small and adorable when they first enter the world. On average, a newborn Frenchie puppy weighs about 6 to 9 ounces. They’re about the size of your hand and can fit comfortably in your palm. These little ones are delicate and require gentle care during their first weeks of life.

As they grow, French Bulldog puppies experience a remarkable transformation. It’s a period of rapid growth and development that should be closely monitored by French Bulldog breeders to make sure every puppy in the litter is developing well. When they are 6 weeks old, the ratio of their body is the closest to what it’s going to be like when they grow up. We recommend to see them at this age, as later in their ‘teenage years’ their limbs can disproportionately grow before changing back at adult age.

By the time they reach 13 to 15 weeks of age (when our puppies travel), Frenchie puppies generally weigh between 8 to 15 lbs . As you’re preparing for getting your new Frenchie, knowing your baby’s expected size could help you choose the right accessories, such as collars, harnesses and crates.

When Do French Bulldogs Stop Growing?

French Bulldogs go through several growth stages, and their growth plates close at different times. Most Frenchies will reach their near-final size within the first eight months of life, but they might continue to fill out and gain muscle mass until they are about one year old.

However, when it comes to weight, French Bulldogs continue to develop for a bit longer. Most Frenchies reach their full weight potential at around 12 to 14 months of age. As a Frenchie parent, it’s important to monitor their growth, and if necessary adjust their diet and exercise accordingly to ensure they grow healthy and not overweight.

How Big Do Frenchies Get?

Frenchies are known for their compact and adorable stature, weighing between 20 to 30 lbs on average once they are fully grown. While some may become a bit lighter or heavier, staying within this range is generally considered healthy for these lovable pups. As for their height, adult Frenchies stand approximately 11 to 13 inches tall at the shoulder.

When it comes to differences between male and female Frenchies’ appearance, we can line out some typical characteristics for both genders. Boys are usually stronger and stockier than girls, they have bigger heads and wider chests. Girl Frenchies tend to be a bit smaller and less muscular. On average, they weigh about 5 lbs less than boys: their adult size is around 25 lbs, while boys can go up to 30 lbs. Read more about the biological differences between boy and girl Frenchies.

Although these are generally true for most dogs, there are always some exceptions to the rule. Whether your future puppy will be bigger or smaller largely depends on the size of the parents, that’s why we always share photos of our puppies’ parents along with their weight information. This way you can get a good idea of what your fur baby will look like as an adult.

What Is the Ideal Size for a Frenchie Crate?

Understanding the expected size of your Frenchie is crucial for various aspects of their care, like selecting the right crate. It’s essential to choose an appropriate size to ensure your Frenchie’s comfort and safety.

The ideal crate size for a French Bulldog is one that allows them to stand up, turn around, and lie down comfortably. Typically, crates in the range of 24 to 30 inches in length work well for adult French Bulldogs. It’s also important not to buy one that’s too big for them; it will not only take up a lot of space but your Frenchie will not feel safe in it either.

All Goes Back to Keeping Your Frenchie Healthy and Happy

Whether you’re caring for a puppy or an adult Frenchie, as a responsible parent your primary focus should be on keeping your furry friend healthy and happy. Obesity can lead to various health issues like joint problems and breathing difficulties, so you need to pay close attention to your Frenchie’s weight by providing regular exercise, a balanced diet and routine veterinary check-ups to ensure they don’t become overweight.

You should also keep in mind that the best-looking French Bulldogs are a bit stockier, so you should always increase and lower the amount of their food with that in mind. Read this article to learn more about maintaining a healthy body weight for your Frenchie.
