French Bulldog Weight Through Life

Can you imagine anything cuter than a French Bulldog? We can. Imagine a Frenchie puppy! Before our thoughts become a gooey mess of snuggles and furry skin folds, let us look at the average weight of French Bulldogs at birth and at each significant age after that.

French Bulldog Weight Range

At birth, French Bulldogs typically weigh around 8 or 10 ounces. They are pretty tiny, and their weight will drop on their first day. This is similar to most newly born mammals, as our bodies let go of fluids we no longer need.

By the second day on the outside, Frenchie puppies begin to gain weight, which is usually steady going from there. When day three rolls around, the tiny puppies should have reached their birth weight and then some.

To provide you with a short overview of the average weight of French Bulldogs in their early lives, we have collated a Frenchie weight chart:

  • Birth: At birth, males are between 8 and 10 ounces. Females are between 7 and 9 ounces.
  • Week 1: Males are between 14 and 17 ounces at a week old. Females weigh between 13-16 ounces. 
  • Week 2: At week two, males weigh between 1.4-1.75 pounds, while females are between 1 and 1.6 ounces.
  • Week 4: By week four, males are up to around 3 pounds. Females linger at about 2 pounds.
  • Week 6: By this stage, male Frenchies weigh between 15.5 and 23.5 pounds, while females weigh between 3 and 3.9 pounds.
  • Month 3: Three months old and packing a punch. At this age, males weigh between 8.5 and 12.8 pounds. Females come in between 7.5 and 12 pounds.
  • Month 6: By this age, male French Bulldogs are between 15.5 and 23.5 pounds, while their female counterparts are between 13.8 and 22 pounds.
  • Year 1: At a year old, the mature male French Bulldog weighs between 19.5 and 28 pounds. The mature female Frenchie weighs between 17.5 and 28 pounds. (Note how male and female adult French Bulldogs can weigh as much as 28 pounds.)

From the points above, it is clear to see how substantial the growth of the French Bulldog is. From a tiny eight ounces to a whopping twenty-eight pounds, Frenchies pack on the pounds, and even at the heaviest weight mentioned here, they are healthy.

Overweight French Bulldog Signs, Complications, And Interventions

A few factors can contribute to a French Bulldog being overweight. Let us look at a few of these to help you either determine the cause of your Frenchie’s excess weight or avoid unnecessary weight gain for your pup.

How Do I Know If My French Bulldog Is Overweight?

Although French Bulldogs are solid dogs, they do not typically have excess body weight. While their faces may remain adorably wrinkled, their bodies should be toned and muscular. 

Here are a few signs that your French Bulldog could be overweight:

1.     Heavy Breathing

Certain dog breeds are prone to heavy breathing. This is caused by a side-effect of breeding and is often one factor that endears us to these types of dogs. However, if your French Bulldog shows signs of heavy or labored breathing after light exercise, it could be cause for concern.

Watch out for signs that your Frenchie is becoming over-exerted by a bit of exercise. It could mean that he is overweight.

2.     Little Or No Definition

French Bulldogs are known for their sturdy frames and muscle definition. If you notice that your dog lacks muscle definition and looks round rather than buff, it could be a sign that they are overweight.

Another sign of excess weight linked to a lack of definition is the inability to feel your dog’s ribs. As you rub your dog’s belly, test if you can feel their ribs through the skin. If you can’t feel them, your dog may be overweight.

3.     Not Enough Reach

Frenchies groom themselves by reaching various parts of their bodies to lick. If your dog struggles to reach essential body parts, he could be overweight. French Bulldogs need to get to the backs of their paws, legs, groin area, and other parts of their bodies.

If your Frenchie is struggling to reach parts of his body that are typically easy to reach, you may consider that he is overweight.

Health Complications For Overweight French Bulldogs

If your French Bulldog is overweight, he might encounter a few health issues now or in the future. You can receive professional advice from your local vet, but here are a few problems your Frenchie could experience.

Any health issue is reason enough to take action for your beloved Frenchie. If you think your dog is overweight, be sure to do what you can to get his weight back to a healthy one.

Interventions For Overweight French Bulldogs

There are a few ideas you can try to bring your dog’s weight back down to an average one for a French Bulldog. Chatting with your vet before taking action with your dog is advisable, but here are a few ideas to consider. (source)

1.     Diet

If your French Bulldog is overweight, consider what you are feeding him. Frenchies thrive on a diet that includes protein. Your dog’s protein should come from animal sources like fish, chicken, and meat. 

Although French Bulldogs are a small breed, they need a relatively large number of calories to sustain their fast metabolism. To keep them from becoming overweight, however, they should consume between 25 and 35 calories per pound of their body weight each day. (source)

2.     Exercise

Your Frenchie is much like any dog, or human for that matter. A lack of exercise will likely lead to excess weight.

To help your French Bulldog stay at a healthy weight, ensure he gets enough exercise. This type of dog is typically sedentary but should do two sessions of about fifteen minutes of exercise per day.


French Bulldogs’ average weight differs between males and females. Males are generally heavier than females. At birth, Frenchies weigh between 7 and 10 ounces. By a year old, males typically weigh between 19.5 and 28 pounds, and females weigh between 17.5 and 28 pounds.

Watch for signs that your French Bulldog is overweight. Overweight Frenchies are prone to health issues and should be assisted if possible. Consult your vet, and then take action to help bring your French Bulldog’s weight back to an acceptable number. A Frenchie that is a healthy weight is likely to live a longer, happier life.
