How Big Does a French Bulldog Get?

French Bulldogs are one of the most beloved small dog breeds, known for their affectionate nature, distinctive bat-like ears, and charming personality. If you're considering adding a French Bulldog to your family, it's crucial to understand their size and growth patterns to ensure you can provide the best care. This comprehensive guide will cover everything you need to know about how big French Bulldogs get, including their average size, growth stages, factors affecting their size, and tips for maintaining a healthy weight.

Average Size of a French Bulldog

French Bulldogs are a small, sturdy breed with a muscular build. Despite their compact size, they have a significant presence. Here's a closer look at their average height and weight:


  • Adult Height: French Bulldogs typically stand between 11 to 12 inches tall at the shoulder. Some may be slightly shorter or taller, but this range is standard for the breed.


  • Adult Weight: The average weight for a healthy adult French Bulldog ranges from 16 to 28 pounds. Males are generally heavier, weighing between 20 to 28 pounds, while females typically weigh between 16 to 24 pounds.

Growth Stages of a French Bulldog

Understanding the growth stages of a French Bulldog can help you monitor their development and ensure they are growing healthily.

Newborn to 8 Weeks

  • Birth Weight: French Bulldog puppies weigh between 8 to 10 ounces at birth.
  • Rapid Growth: During the first few weeks, puppies experience rapid growth, doubling their birth weight within the first week. By 8 weeks, they typically weigh between 5 to 7 pounds.

2 to 6 Months

  • Puppy Growth Spurts: Between 2 to 6 months, French Bulldog puppies continue to grow rapidly. By 6 months, they generally reach about 75% of their adult weight and height.
  • Socialization and Training: This stage is crucial for socialization and training. Introducing your puppy to various environments, people, and other pets will help them develop into a well-adjusted adult.

6 to 12 Months

  • Slower Growth Rate: Growth slows down during this period, but French Bulldogs will continue to gain muscle and fill out. By the end of this stage, they will have reached most of their adult size.
  • Adolescent Phase: Like teenagers, adolescent French Bulldogs may test boundaries and display more energy. Consistent training and exercise are essential.

12 to 24 Months

  • Reaching Full Size: French Bulldogs usually reach their full height by 12 months, but they may continue to gain muscle and fill out until they are about two years old.
  • Adult Weight: By the time they are two years old, French Bulldogs typically reach their full adult weight.

Factors Affecting Size

Several factors can influence the size of a French Bulldog, including genetics, diet, exercise, and overall health.


  • Inherited Traits: The size of a French Bulldog is primarily determined by genetics. If the puppy's parents are larger or smaller than average, their offspring are likely to follow suit.
  • Breeding Practices: Responsible breeders select parent dogs to promote desirable traits, including size. Ensuring your puppy comes from a reputable breeder can give you a better idea of their expected size.

Diet and Nutrition

  • Balanced Diet: Providing a balanced diet is crucial for healthy growth. High-quality puppy food designed for small breeds will ensure your French Bulldog gets the necessary nutrients.
  • Overfeeding/Underfeeding: Overfeeding can lead to obesity, while underfeeding can stunt growth. It's essential to follow your veterinarian's dietary recommendations.

Health and Exercise

  • Regular Vet Check-ups: Routine veterinary care ensures your French Bulldog is growing correctly and maintaining a healthy weight. Early detection of health issues can prevent growth problems.
  • Appropriate Exercise: While French Bulldogs are not highly active dogs, they still need regular exercise. Short walks and playtime are sufficient to keep them healthy and fit.

Maintaining a Healthy Weight

Maintaining a healthy weight is vital for your French Bulldog’s overall well-being. Obesity can lead to various health issues, including joint problems, heart disease, and respiratory difficulties. Here are some tips to help you manage your French Bulldog's size and weight:

Balanced Diet

  • Portion Control: Measure your dog's food to ensure they are getting the right amount. Avoid free-feeding or giving too many treats.
  • High-Quality Food: Choose a high-quality dog food that meets your French Bulldog's nutritional needs. Consult your veterinarian for recommendations.

Regular Exercise

  • Daily Walks: Regular, short walks are essential for maintaining a healthy weight. Aim for at least 30 minutes of exercise per day.
  • Playtime: Engage in interactive play sessions with dog toys to keep your French Bulldog active and mentally stimulated.

Routine Vet Visits

  • Health Monitoring: Regular vet visits allow for monitoring your dog's weight and overall health. Your vet can provide guidance on diet, exercise, and any health concerns.
  • Vaccinations and Preventative Care: Keeping up with vaccinations and preventative care will help prevent illnesses that could affect your dog's growth and health.

Avoid Overfeeding

  • Treats in Moderation: While it's tempting to spoil your French Bulldog with treats, it's essential to do so in moderation. Treats should make up no more than 10% of their daily caloric intake.
  • Healthy Treat Options: Choose healthy treat options, such as small pieces of fruits and vegetables, to avoid unnecessary weight gain.

Health Considerations for French Bulldogs

French Bulldogs are prone to certain health issues due to their unique physical characteristics. Being aware of these conditions can help you manage your dog's health effectively:

Brachycephalic Syndrome

  • Breathing Difficulties: Due to their short snouts, French Bulldogs can experience breathing difficulties, especially in hot or humid weather. Keep them cool and avoid strenuous exercise during extreme temperatures.

Hip Dysplasia

  • Joint Health: Hip dysplasia is a common issue in French Bulldogs. Maintaining a healthy weight and providing joint supplements can help manage this condition.

Skin Allergies

  • Sensitive Skin: French Bulldogs often have sensitive skin prone to allergies. Regular grooming and a balanced diet can help manage skin issues.

Intervertebral Disc Disease (IVDD)

  • Back Problems: IVDD is a common spinal issue in French Bulldogs. Avoid activities that strain their back, such as jumping from heights, to prevent injury.


French Bulldogs are a delightful breed with a manageable size that makes them ideal for various living situations. Understanding how big a French Bulldog can get and the factors that influence their growth will help you provide the best care for your furry friend. By ensuring a balanced diet, regular exercise, and routine vet visits, your French Bulldog will thrive and bring joy to your life for many years. Whether you're welcoming a new puppy or already have an adult Frenchie, this guide will help you keep them healthy and happy.
