At 4 months old, French Bulldog puppies enter an exciting developmental phase often called the "Brat Stage." During this period, these charming puppies experience significant physical and behavioral changes as they transition from early puppyhood toward adolescence. They typically weigh between 12-16 pounds and stand 8-11 inches tall, though individual variations are normal. This stage brings increased independence, testing of boundaries, and the onset of teething. While their playful personalities continue to shine, 4-month-old Frenchies require consistent training, proper nutrition, and dedicated care to develop into well-adjusted adult dogs.

Physical Development

At 4 months, French Bulldog puppies typically weigh between 12-16 lbs for males and 10-15 lbs for females. Their height ranges from 20.3-28 cm (8-11 inches) for males and 21.5-26.7 cm (8.5-10.5 inches) for females.

Behavioral Changes

This stage marks significant behavioral development as puppies enter what's known as the "Juvenile Stage". They become more independent and may start ignoring recently learned commands, similar to a toddler testing boundaries. Play biting might increase during this period. The appropriate response is a firm "No!" command followed by briefly ignoring the puppy. Consistency in training remains crucial for establishing good behavior patterns.

Growth Chart Milestones

According to detailed weight charts, 4-month-old French Bulldogs typically gain 2-4 pounds per month during this stage. Males weigh between 12-16 lbs while females range from 10-15 lbs. Their rapid growth requires careful monitoring to ensure they stay within healthy weight ranges.

Nutrition and Activity Needs

At 4 months, French Bulldog puppies should eat 3 meals daily, totaling approximately 25-30 calories per pound of body weight. Exercise should be limited to 15-20 minutes of moderate activity 2-3 times per day to protect developing joints. Training and play sessions should be kept short but consistent during this stage, as puppies have increased independence but limited attention spans. Monitor activity levels carefully to prevent overexertion, especially in warm weather.

Sensory and Motor Development

While previous sections covered physical growth metrics and behavior, this section focuses specifically on sensory and coordination development. At 4 months, French Bulldog puppies experience rapid sensory development, with improved vision, hearing and motor skills. Their movements become more coordinated as they gain better control over their growing bodies. This is an ideal time to introduce basic agility exercises and interactive toys that challenge their developing senses.

Health Monitoring

Distinct from earlier discussions on feeding and exercise, this section examines key health indicators. According to breed experts, 4-month-old Frenchies should be monitored for proper bone development and joint health as they experience rapid growth. Regular vet checkups are essential during this period to ensure normal development of facial features and breathing passages. Watch for signs of overexertion or respiratory issues during play and exercise.

Conclusion

At 4 months of age, French Bulldog puppies are in a critical developmental stage, marked by significant physical and behavioral changes. Males typically weigh between 12-16 lbs while females range from 10-15 lbs, with height ranging from 8-11 inches. This period represents the "Juvenile Stage" where puppies demonstrate increased independence and may test boundaries with behaviors like play biting and ignoring commands.

Proper nutrition and exercise management are essential during this rapid growth phase, with puppies requiring 3 meals daily and 15-20 minutes of moderate activity 2-3 times per day. Close monitoring of bone development, joint health, and respiratory function is crucial through regular veterinary checkups. Owners should focus on consistent training while being mindful not to overexert their puppies, especially in warm weather. This stage sets the foundation for future physical and behavioral development, making it vital to establish good habits while accommodating their growing independence.
