How big do French Bulldogs grow? French bulldog size guide.
Growth Stages of French Bulldogs
There are three main growth stages for French Bulldogs:
Puppy Stage
Frenchie puppies are small. They are born weighing less than 1 lb. They, however, grow fast during their first 6 months.
Adolescent Stage
This stage starts at around 6 months and ends when your Frenchie is approximately 18 months old. Frenchies develop, albeit at a slower pace, as they mature from puppies to adolescents. It’s critical to keep an eye on their weight and modify their food accordingly.
Adult Stage
Most Frenchies mature to their maximum height by the time they are one year old, though they may keep gaining weight and filling out until they are about two years old. Physical activity is crucial during this stage, as it lowers the chances of obesity.
Factors Influencing Size
Here are the main factors that influence Frenchie Bulldog size:
- Exercise and diet: Lack of exercise and unhealthy food may make your Frenchie bigger than its normal size.
- Genetics: If your Frenchie’s parents were big, the chances of your Frenchie being big are high.
- Health status: Underlying health problems negatively affect your Frenchie’s growth rate.
